-=head1 NAME
-
-EVP_BytesToKey - password based encryption routine
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_BytesToKey(const EVP_CIPHER *type,const EVP_MD *md,
-                       const unsigned char *salt,
-                       const unsigned char *data, int datal, int count,
-                       unsigned char *key,unsigned char *iv);
-
-=head1 DESCRIPTION
-
-EVP_BytesToKey() derives a key and IV from various parameters. B<type> is
-the cipher to derive the key and IV for. B<md> is the message digest to use.
-The B<salt> parameter is used as a salt in the derivation: it should point to
-an 8 byte buffer or NULL if no salt is used. B<data> is a buffer containing
-B<datal> bytes which is used to derive the keying data. B<count> is the
-iteration count to use. The derived key and IV will be written to B<key>
-and B<iv> respectively.
-
-=head1 NOTES
-
-A typical application of this function is to derive keying material for an
-encryption algorithm from a password in the B<data> parameter.
-
-Increasing the B<count> parameter slows down the algorithm which makes it
-harder for an attacker to perform a brute force attack using a large number
-of candidate passwords.
-
-If the total key and IV length is less than the digest length and
-B<MD5> is used then the derivation algorithm is compatible with PKCS#5 v1.5
-otherwise a non standard extension is used to derive the extra data.
-
-Newer applications should use more standard algorithms such as PBKDF2 as
-defined in PKCS#5v2.1 for key derivation.
-
-=head1 KEY DERIVATION ALGORITHM
-
-The key and IV is derived by concatenating D_1, D_2, etc until
-enough data is available for the key and IV. D_i is defined as:
-
-        D_i = HASH^count(D_(i-1) || data || salt)
-
-where || denotes concatenation, D_0 is empty, HASH is the digest
-algorithm in use, HASH^1(data) is simply HASH(data), HASH^2(data)
-is HASH(HASH(data)) and so on.
-
-The initial bytes are used for the key and the subsequent bytes for
-the IV.
-
-=head1 RETURN VALUES
-
-EVP_BytesToKey() returns the size of the derived key in bytes.

-=head1 DESCRIPTION
-
-The EVP digest routines are a high level interface to message digests.
-
-EVP_MD_CTX_init() initializes digest context B<ctx>.
-
-EVP_MD_CTX_create() allocates, initializes and returns a digest context.
-
-EVP_DigestInit_ex() sets up digest context B<ctx> to use a digest
-B<type> from ENGINE B<impl>. B<ctx> must be initialized before calling this
-function. B<type> will typically be supplied by a function such as EVP_sha1().
-If B<impl> is NULL then the default implementation of digest B<type> is used.
-
-EVP_DigestUpdate() hashes B<cnt> bytes of data at B<d> into the
-digest context B<ctx>. This function can be called several times on the
-same B<ctx> to hash additional data.
-
-EVP_DigestFinal_ex() retrieves the digest value from B<ctx> and places
-it in B<md>. If the B<s> parameter is not NULL then the number of
-bytes of data written (i.e. the length of the digest) will be written
-to the integer at B<s>, at most B<EVP_MAX_MD_SIZE> bytes will be written.
-After calling EVP_DigestFinal_ex() no additional calls to EVP_DigestUpdate()
-can be made, but EVP_DigestInit_ex() can be called to initialize a new
-digest operation.
-
-EVP_MD_CTX_cleanup() cleans up digest context B<ctx>, it should be called
-after a digest context is no longer needed.
-
-EVP_MD_CTX_destroy() cleans up digest context B<ctx> and frees up the
-space allocated to it, it should be called only on a context created
-using EVP_MD_CTX_create().
-
-EVP_MD_CTX_copy_ex() can be used to copy the message digest state from
-B<in> to B<out>. This is useful if large amounts of data are to be
-hashed which only differ in the last few bytes. B<out> must be initialized
-before calling this function.
-
-EVP_DigestInit() behaves in the same way as EVP_DigestInit_ex() except
-the passed context B<ctx> does not have to be initialized, and it always
-uses the default digest implementation.
-
-EVP_DigestFinal() is similar to EVP_DigestFinal_ex() except the digest
-context B<ctx> is automatically cleaned up.
-
-EVP_MD_CTX_copy() is similar to EVP_MD_CTX_copy_ex() except the destination
-B<out> does not have to be initialized.
-
-EVP_MD_size() and EVP_MD_CTX_size() return the size of the message digest
-when passed an B<EVP_MD> or an B<EVP_MD_CTX> structure, i.e. the size of the
-hash.
-
-EVP_MD_block_size() and EVP_MD_CTX_block_size() return the block size of the
-message digest when passed an B<EVP_MD> or an B<EVP_MD_CTX> structure.
-
-EVP_MD_type() and EVP_MD_CTX_type() return the NID of the OBJECT IDENTIFIER
-representing the given message digest when passed an B<EVP_MD> structure.
-For example EVP_MD_type(EVP_sha1()) returns B<NID_sha1>. This function is
-normally used when setting ASN1 OIDs.
-
-EVP_MD_CTX_md() returns the B<EVP_MD> structure corresponding to the passed
-B<EVP_MD_CTX>.
-
-EVP_MD_pkey_type() returns the NID of the public key signing algorithm
-associated with this digest. For example EVP_sha1() is associated with RSA so
-this will return B<NID_sha1WithRSAEncryption>. Since digests and signature
-algorithms are no longer linked this function is only retained for
-compatibility reasons.
-
-EVP_md2(), EVP_md5(), EVP_sha1(), EVP_sha224(), EVP_sha256(), EVP_sha384(),
-EVP_sha512() and EVP_ripemd160() return B<EVP_MD> structures for the MD2, MD5,
-SHA1, SHA224, SHA256, SHA384, SHA512 and RIPEMD160 digest algorithms
-respectively.
-
-EVP_dss() and EVP_dss1() return B<EVP_MD> structures for SHA1 digest
-algorithms but using DSS (DSA) for the signature algorithm. Note: there is
-no need to use these pseudo-digests in OpenSSL 1.0.0 and later, they are
-however retained for compatibility.
-
-EVP_md_null() is a "null" message digest that does nothing: i.e. the hash it
-returns is of zero length.
-
-EVP_get_digestbyname(), EVP_get_digestbynid() and EVP_get_digestbyobj()
-return an B<EVP_MD> structure when passed a digest name, a digest NID or
-an ASN1_OBJECT structure respectively. The digest table must be initialized
-using, for example, OpenSSL_add_all_digests() for these functions to work.
-
-=head1 RETURN VALUES
-
-EVP_DigestInit_ex(), EVP_DigestUpdate() and EVP_DigestFinal_ex() return 1 for
-success and 0 for failure.
-
-EVP_MD_CTX_copy_ex() returns 1 if successful or 0 for failure.
-
-EVP_MD_type(), EVP_MD_pkey_type() and EVP_MD_type() return the NID of the
-corresponding OBJECT IDENTIFIER or NID_undef if none exists.
-
-EVP_MD_size(), EVP_MD_block_size(), EVP_MD_CTX_size() and
-EVP_MD_CTX_block_size() return the digest or block size in bytes.
-
-EVP_md_null(), EVP_md2(), EVP_md5(), EVP_sha1(), EVP_dss(),
-EVP_dss1() and EVP_ripemd160() return pointers to the
-corresponding EVP_MD structures.
-
-EVP_get_digestbyname(), EVP_get_digestbynid() and EVP_get_digestbyobj()
-return either an B<EVP_MD> structure or NULL if an error occurs.
-
-=head1 NOTES
-
-The B<EVP> interface to message digests should almost always be used in
-preference to the low level interfaces. This is because the code then becomes
-transparent to the digest used and much more flexible.
-
-New applications should use the SHA2 digest algorithms such as SHA256.
-The other digest algorithms are still in common use.
-
-For most applications the B<impl> parameter to EVP_DigestInit_ex() will be
-set to NULL to use the default digest implementation.
-
-The functions EVP_DigestInit(), EVP_DigestFinal() and EVP_MD_CTX_copy() are
-obsolete but are retained to maintain compatibility with existing code. New
-applications should use EVP_DigestInit_ex(), EVP_DigestFinal_ex() and
-EVP_MD_CTX_copy_ex() because they can efficiently reuse a digest context
-instead of initializing and cleaning it up on each call and allow non default
-implementations of digests to be specified.
-
-In OpenSSL 0.9.7 and later if digest contexts are not cleaned up after use
-memory leaks will occur.
-
-Stack allocation of EVP_MD_CTX structures is common, for example:
-
- EVP_MD_CTX mctx;
- EVP_MD_CTX_init(&mctx);
-
-This will cause binary compatibility issues if the size of EVP_MD_CTX
-structure changes (this will only happen with a major release of OpenSSL).
-Applications wishing to avoid this should use EVP_MD_CTX_create() instead:
-
- EVP_MD_CTX *mctx;
- mctx = EVP_MD_CTX_create();
-
-
-=head1 EXAMPLE
-
-This example digests the data "Test Message\n" and "Hello World\n", using the
-digest name passed on the command line.
-
- #include <stdio.h>
- #include <openssl/evp.h>
-
- int
- main(int argc, char *argv[])
- {
-        EVP_MD_CTX *mdctx;
-        const EVP_MD *md;
-        const char mess1[] = "Test Message\n";
-        const char mess2[] = "Hello World\n";
-        unsigned char md_value[EVP_MAX_MD_SIZE];
-        int md_len, i;
-
-        OpenSSL_add_all_digests();
-
-        if (argc <= 1) {
-                printf("Usage: mdtest digestname\n");
-                exit(1);
-        }
-
-        md = EVP_get_digestbyname(argv[1]);
-        if (md == NULL) {
-                printf("Unknown message digest %s\n", argv[1]);
-                exit(1);
-        }
-
-        mdctx = EVP_MD_CTX_create();
-        EVP_DigestInit_ex(mdctx, md, NULL);
-        EVP_DigestUpdate(mdctx, mess1, strlen(mess1));
-        EVP_DigestUpdate(mdctx, mess2, strlen(mess2));
-        EVP_DigestFinal_ex(mdctx, md_value, &md_len);
-        EVP_MD_CTX_destroy(mdctx);
-
-        printf("Digest is: ");
-        for(i = 0; i < md_len; i++)
-                printf("%02x", md_value[i]);
-        printf("\n");
- }

-EVP_MD_CTX_cleanup(), EVP_MD_CTX_destroy(), EVP_DigestInit_ex()
-and EVP_DigestFinal_ex() were added in OpenSSL 0.9.7.
-
-EVP_md_null(), EVP_md2(), EVP_md5(), EVP_sha1(),
-EVP_dss(), EVP_dss1() and EVP_ripemd160() were
-changed to return truely const EVP_MD * in OpenSSL 0.9.7.
-
-The link between digests and signing algorithms was fixed in OpenSSL 1.0 and
-later, so now EVP_sha1() can be used with RSA and DSA, there is no need to
-use EVP_dss1() any more.
-
-OpenSSL 1.0 and later does not include the MD2 digest algorithm in the

-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_DigestSignInit(EVP_MD_CTX *ctx, EVP_PKEY_CTX **pctx,
-                        const EVP_MD *type, ENGINE *e, EVP_PKEY *pkey);
- int EVP_DigestSignUpdate(EVP_MD_CTX *ctx, const void *d, unsigned int cnt);
- int EVP_DigestSignFinal(EVP_MD_CTX *ctx, unsigned char *sig, size_t *siglen);
-
-=head1 DESCRIPTION
-
-The EVP signature routines are a high level interface to digital signatures.
-
-EVP_DigestSignInit() sets up signing context B<ctx> to use digest B<type> from
-ENGINE B<impl> and private key B<pkey>. B<ctx> must be initialized with
-EVP_MD_CTX_init() before calling this function. If B<pctx> is not NULL the
-EVP_PKEY_CTX of the signing operation will be written to B<*pctx>: this can
-be used to set alternative signing options.
-
-EVP_DigestSignUpdate() hashes B<cnt> bytes of data at B<d> into the
-signature context B<ctx>. This function can be called several times on the
-same B<ctx> to include additional data. This function is currently implemented
-using a macro.
-
-EVP_DigestSignFinal() signs the data in B<ctx> places the signature in B<sig>.
-If B<sig> is B<NULL> then the maximum size of the output buffer is written to
-the B<siglen> parameter. If B<sig> is not B<NULL> then before the call the
-B<siglen> parameter should contain the length of the B<sig> buffer, if the
-call is successful the signature is written to B<sig> and the amount of data
-written to B<siglen>.
-
-=head1 RETURN VALUES
-
-EVP_DigestSignInit() EVP_DigestSignUpdate() and EVP_DigestSignaFinal() return
-1 for success and 0 or a negative value for failure. In particular a return
-value of -2 indicates the operation is not supported by the public key
-algorithm.
-
-The error codes can be obtained from L<ERR_get_error(3)|ERR_get_error(3)>.
-
-=head1 NOTES
-
-The B<EVP> interface to digital signatures should almost always be used in
-preference to the low level interfaces. This is because the code then becomes
-transparent to the algorithm used and much more flexible.
-
-In previous versions of OpenSSL there was a link between message digest types
-and public key algorithms. This meant that "clone" digests such as EVP_dss1()
-needed to be used to sign using SHA1 and DSA. This is no longer necessary and
-the use of clone digest is now discouraged.
-
-The call to EVP_DigestSignFinal() internally finalizes a copy of the digest
-context. This means that calls to EVP_DigestSignUpdate() and
-EVP_DigestSignFinal() can be called later to digest and sign additional data.
-
-Since only a copy of the digest context is ever finalized the context must
-be cleaned up after use by calling EVP_MD_CTX_cleanup() or a memory leak
-will occur.
-
-The use of EVP_PKEY_size() with these functions is discouraged because some
-signature operations may have a signature length which depends on the
-parameters set. As a result EVP_PKEY_size() would have to return a value
-which indicates the maximum possible signature for any set of parameters.

-=head1 DESCRIPTION
-
-The EVP cipher routines are a high level interface to certain
-symmetric ciphers.
-
-EVP_CIPHER_CTX_init() initializes cipher context B<ctx>.
-
-EVP_EncryptInit_ex() sets up cipher context B<ctx> for encryption
-with cipher B<type> from ENGINE B<impl>. B<ctx> must be initialized
-before calling this function. B<type> is normally supplied
-by a function such as EVP_aes_256_cbc(). If B<impl> is NULL then the
-default implementation is used. B<key> is the symmetric key to use
-and B<iv> is the IV to use (if necessary), the actual number of bytes
-used for the key and IV depends on the cipher. It is possible to set
-all parameters to NULL except B<type> in an initial call and supply
-the remaining parameters in subsequent calls, all of which have B<type>
-set to NULL. This is done when the default cipher parameters are not
-appropriate.
-
-EVP_EncryptUpdate() encrypts B<inl> bytes from the buffer B<in> and
-writes the encrypted version to B<out>. This function can be called
-multiple times to encrypt successive blocks of data. The amount
-of data written depends on the block alignment of the encrypted data:
-as a result the amount of data written may be anything from zero bytes
-to (inl + cipher_block_size - 1) so B<outl> should contain sufficient
-room. The actual number of bytes written is placed in B<outl>.
-
-If padding is enabled (the default) then EVP_EncryptFinal_ex() encrypts
-the "final" data, that is any data that remains in a partial block.
-It uses L<standard block padding|/NOTES> (aka PKCS padding). The encrypted
-final data is written to B<out> which should have sufficient space for
-one cipher block. The number of bytes written is placed in B<outl>. After
-this function is called the encryption operation is finished and no further
-calls to EVP_EncryptUpdate() should be made.
-
-If padding is disabled then EVP_EncryptFinal_ex() will not encrypt any more
-data and it will return an error if any data remains in a partial block:
-that is if the total data length is not a multiple of the block size.
-
-EVP_DecryptInit_ex(), EVP_DecryptUpdate() and EVP_DecryptFinal_ex() are the
-corresponding decryption operations. EVP_DecryptFinal() will return an
-error code if padding is enabled and the final block is not correctly
-formatted. The parameters and restrictions are identical to the encryption
-operations except that if padding is enabled the decrypted data buffer B<out>
-passed to EVP_DecryptUpdate() should have sufficient room for
-(B<inl> + cipher_block_size) bytes unless the cipher block size is 1 in
-which case B<inl> bytes is sufficient.
-
-EVP_CipherInit_ex(), EVP_CipherUpdate() and EVP_CipherFinal_ex() are
-functions that can be used for decryption or encryption. The operation
-performed depends on the value of the B<enc> parameter. It should be set
-to 1 for encryption, 0 for decryption and -1 to leave the value unchanged
-(the actual value of 'enc' being supplied in a previous call).
-
-EVP_CIPHER_CTX_cleanup() clears all information from a cipher context
-and free up any allocated memory associate with it. It should be called
-after all operations using a cipher are complete so sensitive information
-does not remain in memory.
-
-EVP_EncryptInit(), EVP_DecryptInit() and EVP_CipherInit() behave in a
-similar way to EVP_EncryptInit_ex(), EVP_DecryptInit_ex and
-EVP_CipherInit_ex() except the B<ctx> parameter does not need to be
-initialized and they always use the default cipher implementation.
-
-EVP_EncryptFinal(), EVP_DecryptFinal() and EVP_CipherFinal() are
-identical to EVP_EncryptFinal_ex(), EVP_DecryptFinal_ex() and
-EVP_CipherFinal_ex(). In previous releases of OpenSSL they also used to clean
-up the B<ctx>, but this is no longer done and EVP_CIPHER_CTX_clean()
-must be called to free any context resources.
-
-EVP_get_cipherbyname(), EVP_get_cipherbynid() and EVP_get_cipherbyobj()
-return an EVP_CIPHER structure when passed a cipher name, a NID or an
-ASN1_OBJECT structure.
-
-EVP_CIPHER_nid() and EVP_CIPHER_CTX_nid() return the NID of a cipher when
-passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX> structure.  The actual NID
-value is an internal value which may not have a corresponding OBJECT
-IDENTIFIER.
-
-EVP_CIPHER_CTX_set_padding() enables or disables padding. By default
-encryption operations are padded using standard block padding and the
-padding is checked and removed when decrypting. If the B<pad> parameter
-is zero then no padding is performed, the total amount of data encrypted
-or decrypted must then be a multiple of the block size or an error will
-occur.
-
-EVP_CIPHER_key_length() and EVP_CIPHER_CTX_key_length() return the key
-length of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>
-structure. The constant B<EVP_MAX_KEY_LENGTH> is the maximum key length
-for all ciphers. Note: although EVP_CIPHER_key_length() is fixed for a
-given cipher, the value of EVP_CIPHER_CTX_key_length() may be different
-for variable key length ciphers.
-
-EVP_CIPHER_CTX_set_key_length() sets the key length of the cipher ctx.
-If the cipher is a fixed length cipher then attempting to set the key
-length to any value other than the fixed value is an error.
-
-EVP_CIPHER_iv_length() and EVP_CIPHER_CTX_iv_length() return the IV
-length of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>.
-It will return zero if the cipher does not use an IV.  The constant
-B<EVP_MAX_IV_LENGTH> is the maximum IV length for all ciphers.
-
-EVP_CIPHER_block_size() and EVP_CIPHER_CTX_block_size() return the block
-size of a cipher when passed an B<EVP_CIPHER> or B<EVP_CIPHER_CTX>
-structure. The constant B<EVP_MAX_IV_LENGTH> is also the maximum block
-length for all ciphers.
-
-EVP_CIPHER_type() and EVP_CIPHER_CTX_type() return the type of the passed
-cipher or context. This "type" is the actual NID of the cipher OBJECT
-IDENTIFIER as such it ignores the cipher parameters and 40 bit RC2 and
-128 bit RC2 have the same NID. If the cipher does not have an object
-identifier or does not have ASN1 support this function will return
-B<NID_undef>.
-
-EVP_CIPHER_CTX_cipher() returns the B<EVP_CIPHER> structure when passed
-an B<EVP_CIPHER_CTX> structure.
-
-EVP_CIPHER_mode() and EVP_CIPHER_CTX_mode() return the block cipher mode:
-EVP_CIPH_ECB_MODE, EVP_CIPH_CBC_MODE, EVP_CIPH_CFB_MODE or
-EVP_CIPH_OFB_MODE. If the cipher is a stream cipher then
-EVP_CIPH_STREAM_CIPHER is returned.
-
-EVP_CIPHER_param_to_asn1() sets the AlgorithmIdentifier "parameter" based
-on the passed cipher. This will typically include any parameters and an
-IV. The cipher IV (if any) must be set when this call is made. This call
-should be made before the cipher is actually "used" (before any
-EVP_EncryptUpdate(), EVP_DecryptUpdate() calls for example). This function
-may fail if the cipher does not have any ASN1 support.
-
-EVP_CIPHER_asn1_to_param() sets the cipher parameters based on an ASN1
-AlgorithmIdentifier "parameter". The precise effect depends on the cipher
-In the case of RC2, for example, it will set the IV and effective key length.
-This function should be called after the base cipher type is set but before
-the key is set. For example EVP_CipherInit() will be called with the IV and
-key set to NULL, EVP_CIPHER_asn1_to_param() will be called and finally
-EVP_CipherInit() again with all parameters except the key set to NULL. It is
-possible for this function to fail if the cipher does not have any ASN1 support
-or the parameters cannot be set (for example the RC2 effective key length
-is not supported.
-
-EVP_CIPHER_CTX_ctrl() allows various cipher specific parameters to be determined
-and set. Currently only the RC2 effective key length and the number of rounds of
-RC5 can be set.

-
-=back
-
-=head1 NOTES
-
-Where possible the B<EVP> interface to symmetric ciphers should be used in
-preference to the low level interfaces. This is because the code then becomes
-transparent to the cipher used and much more flexible.
-
-PKCS padding works by adding B<n> padding bytes of value B<n> to make the total
-length of the encrypted data a multiple of the block size. Padding is always
-added so if the data is already a multiple of the block size B<n> will equal
-the block size. For example if the block size is 8 and 11 bytes are to be
-encrypted then 5 padding bytes of value 5 will be added.
-
-When decrypting the final block is checked to see if it has the correct form.
-
-Although the decryption operation can produce an error if padding is enabled,
-it is not a strong test that the input data or key is correct. A random block
-has better than 1 in 256 chance of being of the correct format and problems with
-the input data earlier on will not produce a final decrypt error.
-
-If padding is disabled then the decryption operation will always succeed if
-the total amount of data decrypted is a multiple of the block size.
-
-The functions EVP_EncryptInit(), EVP_EncryptFinal(), EVP_DecryptInit(),
-EVP_CipherInit() and EVP_CipherFinal() are obsolete but are retained for
-compatibility with existing code. New code should use EVP_EncryptInit_ex(),
-EVP_EncryptFinal_ex(), EVP_DecryptInit_ex(), EVP_DecryptFinal_ex(),
-EVP_CipherInit_ex() and EVP_CipherFinal_ex() because they can reuse an
-existing context without allocating and freeing it up on each call.
-
-=head1 BUGS
-
-For RC5 the number of rounds can currently only be set to 8, 12 or 16. This is
-a limitation of the current RC5 code rather than the EVP interface.
-
-EVP_MAX_KEY_LENGTH and EVP_MAX_IV_LENGTH only refer to the internal ciphers with
-default key lengths. If custom ciphers exceed these values the results are
-unpredictable. This is because it has become standard practice to define a
-generic key as a fixed unsigned char array containing EVP_MAX_KEY_LENGTH bytes.
-
-The ASN1 code is incomplete (and sometimes inaccurate) it has only been tested
-for certain common S/MIME ciphers (RC2, DES, triple DES) in CBC mode.

-=head1 NAME
-
-EVP_OpenInit, EVP_OpenUpdate, EVP_OpenFinal - EVP envelope decryption
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_OpenInit(EVP_CIPHER_CTX *ctx,EVP_CIPHER *type,unsigned char *ek,
-                int ekl,unsigned char *iv,EVP_PKEY *priv);
- int EVP_OpenUpdate(EVP_CIPHER_CTX *ctx, unsigned char *out,
-         int *outl, unsigned char *in, int inl);
- int EVP_OpenFinal(EVP_CIPHER_CTX *ctx, unsigned char *out,
-         int *outl);
-
-=head1 DESCRIPTION
-
-The EVP envelope routines are a high level interface to envelope
-decryption. They decrypt a public key encrypted symmetric key and
-then decrypt data using it.
-
-EVP_OpenInit() initializes a cipher context B<ctx> for decryption
-with cipher B<type>. It decrypts the encrypted symmetric key of length
-B<ekl> bytes passed in the B<ek> parameter using the private key B<priv>.
-The IV is supplied in the B<iv> parameter.
-
-EVP_OpenUpdate() and EVP_OpenFinal() have exactly the same properties
-as the EVP_DecryptUpdate() and EVP_DecryptFinal() routines, as
-documented on the L<EVP_EncryptInit(3)|EVP_EncryptInit(3)> manual
-page.
-
-=head1 NOTES
-
-It is possible to call EVP_OpenInit() twice in the same way as
-EVP_DecryptInit(). The first call should have B<priv> set to NULL
-and (after setting any cipher parameters) it should be called again
-with B<type> set to NULL.
-
-If the cipher passed in the B<type> parameter is a variable length
-cipher then the key length will be set to the value of the recovered
-key length. If the cipher is a fixed length cipher then the recovered
-key length must match the fixed cipher length.
-
-=head1 RETURN VALUES
-
-EVP_OpenInit() returns 0 on error or a non zero integer (actually the
-recovered secret key size) if successful.
-
-EVP_OpenUpdate() returns 1 for success or 0 for failure.
-
-EVP_OpenFinal() returns 0 if the decrypt failed or 1 for success.

-=head1 DESCRIPTION
-
-The function EVP_PKEY_CTX_ctrl() sends a control operation to the context
-B<ctx>. The key type used must match B<keytype> if it is not -1. The parameter
-B<optype> is a mask indicating which operations the control can be applied to.
-The control command is indicated in B<cmd> and any additional arguments in
-B<p1> and B<p2>.
-
-Applications will not normally call EVP_PKEY_CTX_ctrl() directly but will
-instead call one of the algorithm specific macros below.
-
-The function EVP_PKEY_CTX_ctrl_str() allows an application to send an algorithm
-specific control operation to a context B<ctx> in string form. This is
-intended to be used for options specified on the command line or in text
-files. The commands supported are documented in the openssl utility
-command line pages for the option B<-pkeyopt> which is supported by the
-B<pkeyutl>, B<genpkey> and B<req> commands.
-
-All the remaining "functions" are implemented as macros.
-
-The EVP_PKEY_CTX_set_signature_md() macro sets the message digest type used
-in a signature. It can be used with any public key algorithm supporting
-signature operations.
-
-The macro EVP_PKEY_CTX_set_rsa_padding() sets the RSA padding mode for B<ctx>.
-The B<pad> parameter can take the value RSA_PKCS1_PADDING for PKCS#1 padding,
-RSA_SSLV23_PADDING for SSLv23 padding, RSA_NO_PADDING for no padding,
-RSA_PKCS1_OAEP_PADDING for OAEP padding (encrypt and decrypt only),
-RSA_X931_PADDING for X9.31 padding (signature operations only) and
-RSA_PKCS1_PSS_PADDING (sign and verify only).
-
-Two RSA padding modes behave differently if EVP_PKEY_CTX_set_signature_md() is
-used. If this macro is called for PKCS#1 padding the plaintext buffer is an
-actual digest value and is encapsulated in a DigestInfo structure according to
-PKCS#1 when signing and this structure is expected (and stripped off) when
-verifying. If this control is not used with RSA and PKCS#1 padding then the
-supplied data is used directly and not encapsulated. In the case of X9.31
-padding for RSA the algorithm identifier byte is added or checked and removed
-if this control is called. If it is not called then the first byte of the
-plaintext buffer is expected to be the algorithm identifier byte.
-
-The EVP_PKEY_CTX_set_rsa_pss_saltlen() macro sets the RSA PSS salt length to
-B<len> as its name implies it is only supported for PSS padding.  Two special
-values are supported: -1 sets the salt length to the digest length. When
-signing -2 sets the salt length to the maximum permissible value. When
-verifying -2 causes the salt length to be automatically determined based on the
-B<PSS> block structure. If this macro is not called a salt length value of -2
-is used by default.
-
-The EVP_PKEY_CTX_set_rsa_rsa_keygen_bits() macro sets the RSA key length for
-RSA key generation to B<bits>. If not specified 1024 bits is used.
-
-The EVP_PKEY_CTX_set_rsa_keygen_pubexp() macro sets the public exponent value
-for RSA key generation to B<pubexp> currently it should be an odd integer. The
-B<pubexp> pointer is used internally by this function so it should not be
-modified or free after the call. If this macro is not called then 65537 is used.
-
-The macro EVP_PKEY_CTX_set_dsa_paramgen_bits() sets the number of bits used
-for DSA parameter generation to B<bits>. If not specified 1024 is used.
-
-The macro EVP_PKEY_CTX_set_dh_paramgen_prime_len() sets the length of the DH
-prime parameter B<p> for DH parameter generation. If this macro is not called
-then 1024 is used.
-
-The EVP_PKEY_CTX_set_dh_paramgen_generator() macro sets DH generator to B<gen>
-for DH parameter generation. If not specified 2 is used.
-
-The EVP_PKEY_CTX_set_ec_paramgen_curve_nid() sets the EC curve for EC parameter
-generation to B<nid>. For EC parameter generation this macro must be called
-or an error occurs because there is no default curve.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_CTX_ctrl() and its macros return a positive value for success and 0
-or a negative value for failure. In particular a return value of -2
-indicates the operation is not supported by the public key algorithm.

- EVP_PKEY_CTX *EVP_PKEY_CTX_dup(EVP_PKEY_CTX *ctx);
- void EVP_PKEY_CTX_free(EVP_PKEY_CTX *ctx);
-
-=head1 DESCRIPTION
-
-The EVP_PKEY_CTX_new() function allocates public key algorithm context using
-the algorithm specified in B<pkey> and ENGINE B<e>.
-
-The EVP_PKEY_CTX_new_id() function allocates public key algorithm context
-using the algorithm specified by B<id> and ENGINE B<e>. It is normally used
-when no B<EVP_PKEY> structure is associated with the operations, for example
-during parameter generation of key generation for some algorithms.
-
-EVP_PKEY_CTX_dup() duplicates the context B<ctx>.
-
-EVP_PKEY_CTX_free() frees up the context B<ctx>.
-
-=head1 NOTES
-
-The B<EVP_PKEY_CTX> structure is an opaque public key algorithm context used
-by the OpenSSL high level public key API. Contexts B<MUST NOT> be shared between
-threads: that is it is not permissible to use the same context simultaneously
-in two threads.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_CTX_new(), EVP_PKEY_CTX_new_id(), EVP_PKEY_CTX_dup() returns either

-
-EVP_PKEY_encrypt_init, EVP_PKEY_encrypt - encrypt using a public key algorithm
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_PKEY_encrypt_init(EVP_PKEY_CTX *ctx);
- int EVP_PKEY_encrypt(EVP_PKEY_CTX *ctx,
-                        unsigned char *out, size_t *outlen,
-                        const unsigned char *in, size_t inlen);
-
-=head1 DESCRIPTION
-
-The EVP_PKEY_encrypt_init() function initializes a public key algorithm
-context using key B<pkey> for an encryption operation.
-
-The EVP_PKEY_encrypt() function performs a public key encryption operation
-using B<ctx>. The data to be encrypted is specified using the B<in> and
-B<inlen> parameters. If B<out> is B<NULL> then the maximum size of the output
-buffer is written to the B<outlen> parameter. If B<out> is not B<NULL> then
-before the call the B<outlen> parameter should contain the length of the
-B<out> buffer, if the call is successful the encrypted data is written to
-B<out> and the amount of data written to B<outlen>.
-
-=head1 NOTES
-
-After the call to EVP_PKEY_encrypt_init() algorithm specific control
-operations can be performed to set any appropriate parameters for the
-operation.
-
-The function EVP_PKEY_encrypt() can be called more than once on the same
-context if several operations are performed using the same parameters.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_encrypt_init() and EVP_PKEY_encrypt() return 1 for success and 0
-or a negative value for failure. In particular a return value of -2
-indicates the operation is not supported by the public key algorithm.
-

-Encrypt data using OAEP (for RSA keys):
-
- #include <openssl/evp.h>
- #include <openssl/rsa.h>
-
- EVP_PKEY_CTX *ctx;

- size_t outlen, inlen;
- EVP_PKEY *key;
- /* NB: assumes key in, inlen are already set up

-
-=head1 DESCRIPTION
-
-The EVP_PKEY_keygen_init() function initializes a public key algorithm
-context using key B<pkey> for a key generation operation.
-
-The EVP_PKEY_keygen() function performs a key generation operation, the
-generated key is written to B<ppkey>.
-
-The functions EVP_PKEY_paramgen_init() and EVP_PKEY_paramgen() are similar
-except parameters are generated.
-
-The function EVP_PKEY_set_cb() sets the key or parameter generation callback
-to B<cb>. The function EVP_PKEY_CTX_get_cb() returns the key or parameter
-generation callback.
-
-The function EVP_PKEY_CTX_get_keygen_info() returns parameters associated
-with the generation operation. If B<idx> is -1 the total number of
-parameters available is returned. Any non negative value returns the value of
-that parameter. EVP_PKEY_CTX_gen_keygen_info() with a non-negative value for
-B<idx> should only be called within the generation callback.
-
-If the callback returns 0 then the key generation operation is aborted and an
-error occurs. This might occur during a time consuming operation where
-a user clicks on a "cancel" button.
-
-The functions EVP_PKEY_CTX_set_app_data() and EVP_PKEY_CTX_get_app_data() set
-and retrieve an opaque pointer. This can be used to set some application
-defined value which can be retrieved in the callback: for example a handle
-which is used to update a "progress dialog".
-
-=head1 NOTES
-
-After the call to EVP_PKEY_keygen_init() or EVP_PKEY_paramgen_init() algorithm
-specific control operations can be performed to set any appropriate parameters
-for the operation.
-
-The functions EVP_PKEY_keygen() and EVP_PKEY_paramgen() can be called more than
-once on the same context if several operations are performed using the same
-parameters.
-
-The meaning of the parameters passed to the callback will depend on the
-algorithm and the specific implementation of the algorithm. Some might not
-give any useful information at all during key or parameter generation. Others
-might not even call the callback.
-
-The operation performed by key or parameter generation depends on the algorithm
-used. In some cases (e.g. EC with a supplied named curve) the "generation"
-option merely sets the appropriate fields in an EVP_PKEY structure.
-
-In OpenSSL an EVP_PKEY structure containing a private key also contains the
-public key components and parameters (if any). An OpenSSL private key is
-equivalent to what some libraries call a "key pair". A private key can be used
-in functions which require the use of a public key or parameters.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_keygen_init(), EVP_PKEY_paramgen_init(), EVP_PKEY_keygen() and
-EVP_PKEY_paramgen() return 1 for success and 0 or a negative value for failure.
-In particular a return value of -2 indicates the operation is not supported by
-the public key algorithm.

-
-=head1 DESCRIPTION
-
-The functions EVP_PKEY_print_public(), EVP_PKEY_print_private() and
-EVP_PKEY_print_params() print out the public, private or parameter components
-of key B<pkey> respectively. The key is sent to BIO B<out> in human readable
-form. The parameter B<indent> indicated how far the printout should be indented.
-
-The B<pctx> parameter allows the print output to be finely tuned by using
-ASN1 printing options. If B<pctx> is set to NULL then default values will
-be used.
-
-=head1 NOTES
-
-Currently no public key algorithms include any options in the B<pctx> parameter
-parameter.
-
-If the key does not include all the components indicated by the function then
-only those contained in the key will be printed. For example passing a public
-key to EVP_PKEY_print_private() will only print the public components.

-
-=head1 DESCRIPTION
-
-The EVP_PKEY_sign_init() function initializes a public key algorithm
-context using key B<pkey> for a signing operation.
-
-The EVP_PKEY_sign() function performs a public key signing operation
-using B<ctx>. The data to be signed is specified using the B<tbs> and
-B<tbslen> parameters. If B<sig> is B<NULL> then the maximum size of the output

-before the call the B<siglen> parameter should contain the length of the
-B<sig> buffer, if the call is successful the signature is written to
-B<sig> and the amount of data written to B<siglen>.
-
-=head1 NOTES
-
-After the call to EVP_PKEY_sign_init() algorithm specific control
-operations can be performed to set any appropriate parameters for the
-operation.
-
-The function EVP_PKEY_sign() can be called more than once on the same
-context if several operations are performed using the same parameters.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_sign_init() and EVP_PKEY_sign() return 1 for success and 0
-or a negative value for failure. In particular a return value of -2
-indicates the operation is not supported by the public key algorithm.

-=head1 NAME
-
-EVP_PKEY_verify_init, EVP_PKEY_verify - signature verification using a public
-key algorithm
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_PKEY_verify_init(EVP_PKEY_CTX *ctx);
- int EVP_PKEY_verify(EVP_PKEY_CTX *ctx,
-                        const unsigned char *sig, size_t siglen,
-                        const unsigned char *tbs, size_t tbslen);
-
-=head1 DESCRIPTION
-
-The EVP_PKEY_verify_init() function initializes a public key algorithm
-context using key B<pkey> for a signature verification operation.
-
-The EVP_PKEY_verify() function performs a public key verification operation
-using B<ctx>. The signature is specified using the B<sig> and
-B<siglen> parameters. The verified data (i.e. the data believed originally
-signed) is specified using the B<tbs> and B<tbslen> parameters.
-
-=head1 NOTES
-
-After the call to EVP_PKEY_verify_init() algorithm specific control
-operations can be performed to set any appropriate parameters for the
-operation.
-
-The function EVP_PKEY_verify() can be called more than once on the same
-context if several operations are performed using the same parameters.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_verify_init() and EVP_PKEY_verify() return 1 if the verification was
-successful and 0 if it failed. Unlike other functions the return value 0 from
-EVP_PKEY_verify() only indicates that the signature did not verify
-successfully (that is tbs did not match the original data or the signature was
-of invalid form) it is not an indication of a more serious error.
-
-A negative value indicates an error other that signature verification failure.
-In particular a return value of -2 indicates the operation is not supported by
-the public key algorithm.
-
-=head1 EXAMPLE
-
-Verify signature using PKCS#1 and SHA256 digest:
-
- #include <openssl/evp.h>
- #include <openssl/rsa.h>
-
- EVP_PKEY_CTX *ctx;
- unsigned char *md, *sig;
- size_t mdlen, siglen;
- EVP_PKEY *verify_key;
- /* NB: assumes verify_key, sig, siglen md and mdlen are already set up
-  * and that verify_key is an RSA public key
-  */
- ctx = EVP_PKEY_CTX_new(verify_key);
- if (!ctx)
-        /* Error occurred */
- if (EVP_PKEY_verify_init(ctx) <= 0)
-        /* Error */
- if (EVP_PKEY_CTX_set_rsa_padding(ctx, RSA_PKCS1_PADDING) <= 0)
-        /* Error */
- if (EVP_PKEY_CTX_set_signature_md(ctx, EVP_sha256()) <= 0)
-        /* Error */
-
- /* Perform operation */
- ret = EVP_PKEY_verify(ctx, sig, siglen, md, mdlen);
-
- /* ret == 1 indicates success, 0 verify failure and < 0 for some
-  * other error.

-
-=head1 DESCRIPTION
-
-The EVP_PKEY_verify_recover_init() function initializes a public key algorithm
-context using key B<pkey> for a verify recover operation.
-
-The EVP_PKEY_verify_recover() function recovers signed data
-using B<ctx>. The signature is specified using the B<sig> and
-B<siglen> parameters. If B<rout> is B<NULL> then the maximum size of the output
-buffer is written to the B<routlen> parameter. If B<rout> is not B<NULL> then
-before the call the B<routlen> parameter should contain the length of the
-B<rout> buffer, if the call is successful recovered data is written to
-B<rout> and the amount of data written to B<routlen>.
-
-=head1 NOTES
-
-Normally an application is only interested in whether a signature verification
-operation is successful in those cases the EVP_verify() function should be
-used.
-
-Sometimes however it is useful to obtain the data originally signed using a
-signing operation. Only certain public key algorithms can recover a signature
-in this way (for example RSA in PKCS padding mode).
-
-After the call to EVP_PKEY_verify_recover_init() algorithm specific control

-operation.
-
-The function EVP_PKEY_verify_recover() can be called more than once on the same
-context if several operations are performed using the same parameters.

-EVP_PKEY_verify_recover_init() and EVP_PKEY_verify_recover() return 1 for

-
-EVP_SealInit, EVP_SealUpdate, EVP_SealFinal - EVP envelope encryption
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
- int EVP_SealInit(EVP_CIPHER_CTX *ctx, const EVP_CIPHER *type,
-                  unsigned char **ek, int *ekl, unsigned char *iv,
-                  EVP_PKEY **pubk, int npubk);
- int EVP_SealUpdate(EVP_CIPHER_CTX *ctx, unsigned char *out,
-         int *outl, unsigned char *in, int inl);
- int EVP_SealFinal(EVP_CIPHER_CTX *ctx, unsigned char *out,
-         int *outl);
-
-=head1 DESCRIPTION
-
-The EVP envelope routines are a high level interface to envelope
-encryption. They generate a random key and IV (if required) then
-"envelope" it by using public key encryption. Data can then be
-encrypted using this key.
-
-EVP_SealInit() initializes a cipher context B<ctx> for encryption
-with cipher B<type> using a random secret key and IV. B<type> is normally
-supplied by a function such as EVP_aes_256_cbc(). The secret key is encrypted
-using one or more public keys, this allows the same encrypted data to be
-decrypted using any of the corresponding private keys. B<ek> is an array of
-buffers where the public key encrypted secret key will be written, each buffer
-must contain enough room for the corresponding encrypted key: that is
-B<ek[i]> must have room for B<EVP_PKEY_size(pubk[i])> bytes. The actual
-size of each encrypted secret key is written to the array B<ekl>. B<pubk> is
-an array of B<npubk> public keys.
-
-The B<iv> parameter is a buffer where the generated IV is written to. It must
-contain enough room for the corresponding cipher's IV, as determined by (for
-example) EVP_CIPHER_iv_length(type).
-
-If the cipher does not require an IV then the B<iv> parameter is ignored
-and can be B<NULL>.
-
-EVP_SealUpdate() and EVP_SealFinal() have exactly the same properties
-as the EVP_EncryptUpdate() and EVP_EncryptFinal() routines, as
-documented on the L<EVP_EncryptInit(3)|EVP_EncryptInit(3)> manual
-page.
-
-=head1 RETURN VALUES
-
-EVP_SealInit() returns 0 on error or B<npubk> if successful.
-
-EVP_SealUpdate() and EVP_SealFinal() return 1 for success and 0 for
-failure.
-
-=head1 NOTES
-
-The public key must be RSA because it is the only OpenSSL public key
-algorithm that supports key transport.
-
-Envelope encryption is the usual method of using public key encryption
-on large amounts of data, this is because public key encryption is slow
-but symmetric encryption is fast. So symmetric encryption is used for
-bulk encryption and the small random symmetric key used is transferred
-using public key encryption.
-
-It is possible to call EVP_SealInit() twice in the same way as
-EVP_EncryptInit(). The first call should have B<npubk> set to 0
-and (after setting any cipher parameters) it should be called again
-with B<type> set to NULL.

-
- #include <openssl/evp.h>
-
- int EVP_SignInit_ex(EVP_MD_CTX *ctx, const EVP_MD *type, ENGINE *impl);
- int EVP_SignUpdate(EVP_MD_CTX *ctx, const void *d, unsigned int cnt);

-
- int EVP_PKEY_size(EVP_PKEY *pkey);
-
-=head1 DESCRIPTION
-
-The EVP signature routines are a high level interface to digital
-signatures.
-
-EVP_SignInit_ex() sets up signing context B<ctx> to use digest
-B<type> from ENGINE B<impl>. B<ctx> must be initialized with
-EVP_MD_CTX_init() before calling this function.
-
-EVP_SignUpdate() hashes B<cnt> bytes of data at B<d> into the
-signature context B<ctx>. This function can be called several times on the
-same B<ctx> to include additional data.
-
-EVP_SignFinal() signs the data in B<ctx> using the private key B<pkey> and
-places the signature in B<sig>. B<sig> must be at least EVP_PKEY_size(pkey)
-bytes in size. B<s> is an OUT parameter, and not used as an IN parameter.
-The number of bytes of data written (i.e. the length of the signature)
-will be written to the integer at B<s>, at most EVP_PKEY_size(pkey) bytes
-will be written.
-
-EVP_SignInit() initializes a signing context B<ctx> to use the default
-implementation of digest B<type>.
-
-EVP_PKEY_size() returns the maximum size of a signature in bytes. The actual
-signature returned by EVP_SignFinal() may be smaller.
-
-=head1 RETURN VALUES
-
-EVP_SignInit_ex(), EVP_SignUpdate() and EVP_SignFinal() return 1
-for success and 0 for failure.
-
-EVP_PKEY_size() returns the maximum size of a signature in bytes.
-
-The error codes can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
-
-=head1 NOTES
-
-The B<EVP> interface to digital signatures should almost always be used in
-preference to the low level interfaces. This is because the code then becomes
-transparent to the algorithm used and much more flexible.
-
-Due to the link between message digests and public key algorithms the correct
-digest algorithm must be used with the correct public key type. A list of
-algorithms and associated public key algorithms appears in
-L<EVP_DigestInit(3)|EVP_DigestInit(3)>.
-
-The call to EVP_SignFinal() internally finalizes a copy of the digest context.
-This means that calls to EVP_SignUpdate() and EVP_SignFinal() can be called
-later to digest and sign additional data.
-
-Since only a copy of the digest context is ever finalized the context must
-be cleaned up after use by calling EVP_MD_CTX_cleanup() or a memory leak
-will occur.
-
-=head1 BUGS
-
-Older versions of this documentation wrongly stated that calls to
-EVP_SignUpdate() could not be made after calling EVP_SignFinal().
-
-Since the private key is passed in the call to EVP_SignFinal() any error
-relating to the private key (for example an unsuitable key and digest
-combination) will not be indicated until after potentially large amounts of
-data have been passed through EVP_SignUpdate().
-
-It is not possible to change the signing parameters using these function.

-
-evp - high-level cryptographic functions
-
-=head1 SYNOPSIS
-
- #include <openssl/evp.h>
-
-=head1 DESCRIPTION
-
-The EVP library provides a high-level interface to cryptographic
-functions.
-
-L<B<EVP_Seal>I<...>|EVP_SealInit(3)> and L<B<EVP_Open>I<...>|EVP_OpenInit(3)>
-provide public key encryption and decryption to implement digital "envelopes".
-
-The L<B<EVP_DigestSign>I<...>|EVP_DigestSignInit(3)> and
-L<B<EVP_DigestVerify>I<...>|EVP_DigestVerifyInit(3)> functions implement
-digital signatures and Message Authentication Codes (MACs). Also see the older
-L<B<EVP_Sign>I<...>|EVP_SignInit(3)> and L<B<EVP_Verify>I<...>|EVP_VerifyInit(3)>
-functions.
-
-Symmetric encryption is available with the L<B<EVP_Encrypt>I<...>|EVP_EncryptInit(3)>
-functions.  The L<B<EVP_Digest>I<...>|EVP_DigestInit(3)> functions provide message digests.
-
-Authenticated encryption with additional data (AEAD) is available with
-the L<B<EVP_AEAD>I<...>|EVP_AEAD_CTX_init(3)> functions.
-
-The B<EVP_PKEY>I<...> functions provide a high level interface to
-asymmetric algorithms. To create a new EVP_PKEY see
-L<EVP_PKEY_new(3)|EVP_PKEY_new(3)>. EVP_PKEYs can be associated
-with a private key of a particular algorithm by using the functions
-described on the L<EVP_PKEY_set1_RSA(3)|EVP_PKEY_set1_RSA(3)> page, or
-new keys can be generated using L<EVP_PKEY_keygen(3)|EVP_PKEY_keygen(3)>.
-EVP_PKEYs can be compared using L<EVP_PKEY_cmp(3)|EVP_PKEY_cmp(3)>, or printed using
-L<EVP_PKEY_print_private(3)|EVP_PKEY_print_private(3)>.
-
-The EVP_PKEY functions support the full range of asymmetric algorithm operations:
-
-=over
-
-=item For key agreement see L<EVP_PKEY_derive(3)|EVP_PKEY_derive(3)>
-
-=item For signing and verifying see L<EVP_PKEY_sign(3)|EVP_PKEY_sign(3)>,
-L<EVP_PKEY_verify(3)|EVP_PKEY_verify(3)> and L<EVP_PKEY_verify_recover(3)|EVP_PKEY_verify_recover(3)>.
-However, note that
-these functions do not perform a digest of the data to be signed. Therefore
-normally you would use the L<B<EVP_DigestSign>I<...>|EVP_DigestSignInit(3)>
-functions for this purpose.
-
-=item For encryption and decryption see L<EVP_PKEY_encrypt(3)|EVP_PKEY_encrypt(3)>
-and L<EVP_PKEY_decrypt(3)|EVP_PKEY_decrypt(3)> respectively. However, note that
-these functions perform encryption and decryption only. As public key
-encryption is an expensive operation, normally you would wrap
-an encrypted message in a "digital envelope" using the L<B<EVP_Seal>I<...>|EVP_SealInit(3)> and
-L<B<EVP_Open>I<...>|EVP_OpenInit(3)> functions.
-
-=back
-
-The L<EVP_BytesToKey(3)|EVP_BytesToKey(3)> function provides some limited support for password
-based encryption. Careful selection of the parameters will provide a PKCS#5 PBKDF1 compatible
-implementation. However, new applications should not typically use this (preferring, for example,
-PBKDF2 from PCKS#5).
-
-Algorithms are loaded with L<OpenSSL_add_all_algorithms(3)|OpenSSL_add_all_algorithms(3)>.
-
-All the symmetric algorithms (ciphers), digests and asymmetric algorithms
-(public key algorithms) can be replaced by L<ENGINE|engine(3)> modules providing alternative
-implementations. If ENGINE implementations of ciphers or digests are registered
-as defaults, then the various EVP functions will automatically use those
-implementations automatically in preference to built in software
-implementations. For more information, consult the engine(3) man page.
-
-Although low level algorithm specific functions exist for many algorithms
-their use is discouraged. They cannot be used with an ENGINE and ENGINE
-versions of new algorithms cannot be accessed using the low level functions.
-Also makes code harder to adapt to new algorithms and some options are not
-cleanly supported at the low level and some operations are more efficient
-using the high level interface.

+.Fc
+.Sh DESCRIPTION
+.Fn EVP_BytesToKey
+derives a key and IV from various parameters.
+.Fa type
+is the cipher to derive the key and IV for.
+.Fa md
+is the message digest to use.
+The
+.Fa salt
+parameter is used as a salt in the derivation: it should point to an 8
+byte buffer or
+.Dv NULL
+if no salt is used.
+.Fa data
+is a buffer containing
+.Fa datal
+bytes which is used to derive the keying data.
+.Fa count
+is the iteration count to use.
+The derived key and IV will be written to
+.Fa key
+and
+.Fa iv ,
+respectively.
+.Pp
+A typical application of this function is to derive keying material for
+an encryption algorithm from a password in the
+.Fa data
+parameter.
+.Pp
+Increasing the
+.Fa count
+parameter slows down the algorithm which makes it harder for an attacker
+to perform a brute force attack using a large number of candidate
+passwords.
+.Pp
+If the total key and IV length is less than the digest length and MD5
+is used, then the derivation algorithm is compatible with PKCS#5 v1.5.
+Otherwise, a non standard extension is used to derive the extra data.
+.Pp
+Newer applications should use more standard algorithms such as PBKDF2 as
+defined in PKCS#5v2.1 for key derivation.
+.Sh KEY DERIVATION ALGORITHM
+The key and IV is derived by concatenating D_1, D_2, etc until enough
+data is available for the key and IV.
+D_i is defined recursively as:
+.Pp
+.Dl D_i = HASH^count(D_(i-1) || data || salt)
+.Pp
+where || denotes concatenation, D_0 is empty, HASH is the digest
+algorithm in use, HASH^1(data) is simply HASH(data), HASH^2(data) is
+HASH(HASH(data)) and so on.
+.Pp
+The initial bytes are used for the key and the subsequent bytes for the
+IV.
+.Sh RETURN VALUES
+.Fn EVP_BytesToKey
+returns the size of the derived key in bytes.

+.Sh DESCRIPTION
+The EVP digest routines are a high level interface to message digests.
+.Pp
+.Fn EVP_MD_CTX_init
+initializes the digest context
+.Fa ctx .
+.Pp
+.Fn EVP_MD_CTX_create
+allocates, initializes, and returns a digest context.
+.Pp
+.Fn EVP_DigestInit_ex
+sets up digest context
+.Fa ctx
+to use a digest
+.Fa type
+from
+.Vt ENGINE
+.Fa impl .
+.Fa ctx
+must be initialized before calling this function.
+.Fa type
+will typically be supplied by a function such as
+.Fn EVP_sha1 .
+If
+.Fa impl
+is
+.Dv NULL ,
+then the default implementation of digest
+.Fa type
+is used.
+.Pp
+.Fn EVP_DigestUpdate
+hashes
+.Fa cnt
+bytes of data at
+.Fa d
+into the digest context
+.Fa ctx .
+This function can be called several times on the same
+.Fa ctx
+to hash additional data.
+.Pp
+.Fn EVP_DigestFinal_ex
+retrieves the digest value from
+.Fa ctx
+and places it in
+.Fa md .
+If the
+.Fa s
+parameter is not
+.Dv NULL ,
+then the number of bytes of data written (i.e. the length of the
+digest) will be written to the integer at
+.Fa s ,
+at most
+.Dv EVP_MAX_MD_SIZE
+bytes will be written.
+After calling
+.Fn EVP_DigestFinal_ex ,
+no additional calls to
+.Fn EVP_DigestUpdate
+can be made, but
+.Fn EVP_DigestInit_ex
+can be called to initialize a new digest operation.
+.Pp
+.Fn EVP_MD_CTX_cleanup
+cleans up the digest context
+.Fa ctx .
+It should be called after a digest context is no longer needed.
+.Pp
+.Fn EVP_MD_CTX_destroy
+cleans up the digest context
+.Fa ctx
+and frees up the space allocated to it.
+It should be called only on a context created using
+.Fn EVP_MD_CTX_create .
+.Pp
+.Fn EVP_MD_CTX_copy_ex
+can be used to copy the message digest state from
+.Fa in
+to
+.Fa out .
+This is useful if large amounts of data are to be hashed which only
+differ in the last few bytes.
+.Fa out
+must be initialized before calling this function.
+.Pp
+.Fn EVP_DigestInit
+behaves in the same way as
+.Fn EVP_DigestInit_ex
+except the passed context
+.Fa ctx
+does not have to be initialized, and it always uses the default digest
+implementation.
+.Pp
+.Fn EVP_DigestFinal
+is similar to
+.Fn EVP_DigestFinal_ex
+except the digest context
+.Fa ctx
+is automatically cleaned up.
+.Pp
+.Fn EVP_MD_CTX_copy
+is similar to
+.Fn EVP_MD_CTX_copy_ex
+except the destination
+.Fa out
+does not have to be initialized.
+.Pp
+.Fn EVP_MD_size
+and
+.Fn EVP_MD_CTX_size
+return the size of the message digest when passed an
+.Vt EVP_MD
+or an
+.Vt EVP_MD_CTX
+structure, i.e. the size of the hash.
+.Pp
+.Fn EVP_MD_block_size
+and
+.Fn EVP_MD_CTX_block_size
+return the block size of the message digest when passed an
+.Vt EVP_MD
+or an
+.Vt EVP_MD_CTX
+structure.
+.Pp
+.Fn EVP_MD_type
+and
+.Fn EVP_MD_CTX_type
+return the NID of the OBJECT IDENTIFIER representing the given message
+digest when passed an
+.Vt EVP_MD
+structure.
+For example
+.Fn EVP_MD_type EVP_sha1()
+returns
+.Dv NID_sha1 .
+This function is normally used when setting ASN1 OIDs.
+.Pp
+.Fn EVP_MD_CTX_md
+returns the
+.Vt EVP_MD
+structure corresponding to the passed
+.Vt EVP_MD_CTX .
+.Pp
+.Fn EVP_MD_pkey_type
+returns the NID of the public key signing algorithm associated with this
+digest.
+For example
+.Fn EVP_sha1
+is associated with RSA so this will return
+.Dv NID_sha1WithRSAEncryption .
+Since digests and signature algorithms are no longer linked this
+function is only retained for compatibility reasons.
+.Pp
+.Fn EVP_md2 ,
+.Fn EVP_md5 ,
+.Fn EVP_sha1 ,
+.Fn EVP_sha224 ,
+.Fn EVP_sha256 ,
+.Fn EVP_sha384 ,
+.Fn EVP_sha512 ,
+and
+.Fn EVP_ripemd160
+return
+.Vt EVP_MD
+structures for the MD2, MD5, SHA1, SHA224, SHA256, SHA384, SHA512 and
+RIPEMD160 digest algorithms respectively.
+.Pp
+.Fn EVP_dss
+and
+.Fn EVP_dss1
+return
+.Vt EVP_MD
+structures for SHA1 digest algorithms but using DSS (DSA) for the
+signature algorithm.
+Note: there is no need to use these pseudo-digests in OpenSSL 1.0.0 and
+later, they are however retained for compatibility.
+.Pp
+.Fn EVP_md_null
+is a "null" message digest that does nothing:
+i.e. the hash it returns is of zero length.
+.Pp
+.Fn EVP_get_digestbyname ,
+.Fn EVP_get_digestbynid ,
+and
+.Fn EVP_get_digestbyobj
+return an
+.Vt EVP_MD
+structure when passed a digest name, a digest NID, or an ASN1_OBJECT
+structure respectively.
+The digest table must be initialized using, for example,
+.Xr OpenSSL_add_all_digests 3
+for these functions to work.
+.Pp
+The EVP interface to message digests should almost always be used
+in preference to the low level interfaces.
+This is because the code then becomes transparent to the digest used and
+much more flexible.
+.Pp
+New applications should use the SHA2 digest algorithms such as SHA256.
+The other digest algorithms are still in common use.
+.Pp
+For most applications the
+.Fa impl
+parameter to
+.Fn EVP_DigestInit_ex
+will be set to NULL to use the default digest implementation.
+.Pp
+The functions
+.Fn EVP_DigestInit ,
+.Fn EVP_DigestFinal ,
+and
+.Fn EVP_MD_CTX_copy
+are obsolete but are retained to maintain compatibility with existing
+code.
+New applications should use
+.Fn EVP_DigestInit_ex ,
+.Fn EVP_DigestFinal_ex ,
+and
+.Fn EVP_MD_CTX_copy_ex
+because they can efficiently reuse a digest context instead of
+initializing and cleaning it up on each call and allow non default
+implementations of digests to be specified.
+.Pp
+In OpenSSL 0.9.7 and later if digest contexts are not cleaned up after
+use memory leaks will occur.
+.Pp
+Stack allocation of
+.Vt EVP_MD_CTX
+structures is common, for example:
+.Bd -literal -offset indent
+EVP_MD_CTX mctx;
+EVP_MD_CTX_init(&mctx);
+.Ed
+.Pp
+This will cause binary compatibility issues if the size of
+.Vt EVP_MD_CTX
+structure changes (this will only happen with a major release of OpenSSL).
+Applications wishing to avoid this should use
+.Fn EVP_MD_CTX_create
+instead:
+.Bd -literal -offset indent
+EVP_MD_CTX *mctx;
+mctx = EVP_MD_CTX_create();
+.Ed
+.Sh RETURN VALUES
+.Fn EVP_DigestInit_ex ,
+.Fn EVP_DigestUpdate ,
+.Fn EVP_DigestFinal_ex ,
+and
+.Fn EVP_MD_CTX_copy_ex
+return 1 for success or 0 for failure.
+.Pp
+.Fn EVP_MD_type ,
+.Fn EVP_MD_pkey_type ,
+and
+.Fn EVP_MD_type
+return the NID of the corresponding OBJECT IDENTIFIER or
+.Dv NID_undef
+if none exists.
+.Pp
+.Fn EVP_MD_size ,
+.Fn EVP_MD_block_size ,
+.Fn EVP_MD_CTX_size ,
+and
+.Fn EVP_MD_CTX_block_size
+return the digest or block size in bytes.
+.Pp
+.Fn EVP_md_null ,
+.Fn EVP_md2 ,
+.Fn EVP_md5 ,
+.Fn EVP_sha1 ,
+.Fn EVP_dss ,
+.Fn EVP_dss1 ,
+and
+.Fn EVP_ripemd160
+return pointers to the corresponding
+.Vt EVP_MD
+structures.
+.Pp
+.Fn EVP_get_digestbyname ,
+.Fn EVP_get_digestbynid ,
+and
+.Fn EVP_get_digestbyobj
+return either an
+.Vt EVP_MD
+structure or
+.Dv NULL
+if an error occurs.

+The EVP signature routines are a high level interface to digital
+signatures.
+.Pp
+.Fn EVP_DigestSignInit
+sets up the signing context
+.Fa ctx
+to use the digest
+.Fa type
+from
+.Vt ENGINE
+.Fa e
+and private key
+.Fa pkey .
+.Fa ctx
+must be initialized with
+.Xr EVP_MD_CTX_init 3
+before calling this function.
+If
+.Fa pctx
+is not
+.Dv NULL ,
+the
+.Vt EVP_PKEY_CTX
+of the signing operation will be written to

+this can be used to set alternative signing options.
+.Pp
+.Fn EVP_DigestSignUpdate
+hashes
+.Fa cnt
+bytes of data at
+.Fa d
+into the signature context
+.Fa ctx .
+This function can be called several times on the same
+.Fa ctx
+to include additional data.
+This function is currently implemented using a macro.
+.Pp
+.Fn EVP_DigestSignFinal
+signs the data in
+.Fa ctx
+and places the signature in
+.Fa sig .
+If
+.Fa sig
+is
+.Dv NULL ,
+then the maximum size of the output buffer is written to
+.Pf * Fa siglen .
+If
+.Fa sig
+is not
+.Dv NULL ,
+then before the call
+.Fa siglen
+should contain the length of the
+.Fa sig
+buffer.
+If the call is successful, the signature is written to
+.Fa sig
+and the amount of data written to
+.Fa siglen .
+.Pp
+The EVP interface to digital signatures should almost always be
+used in preference to the low level interfaces.
+This is because the code then becomes transparent to the algorithm used
+and much more flexible.
+.Pp
+In previous versions of OpenSSL, there was a link between message digest
+types and public key algorithms.
+This meant that "clone" digests such as
+.Xr EVP_dss1 3
+needed to be used to sign using SHA1 and DSA.
+This is no longer necessary and the use of clone digest is now
+discouraged.
+.Pp
+The call to
+.Fn EVP_DigestSignFinal
+internally finalizes a copy of the digest context.
+This means that
+.Fn EVP_DigestSignUpdate
+and
+.Fn EVP_DigestSignFinal
+can be called later to digest and sign additional data.
+.Pp
+Since only a copy of the digest context is ever finalized, the context
+must be cleaned up after use by calling
+.Xr EVP_MD_CTX_cleanup 3 ,
+or a memory leak will occur.
+.Pp
+The use of
+.Xr EVP_PKEY_size 3
+with these functions is discouraged because some signature operations
+may have a signature length which depends on the parameters set.
+As a result,
+.Xr EVP_PKEY_size 3
+would have to return a value which indicates the maximum possible
+signature for any set of parameters.
+.Sh RETURN VALUES
+.Fn EVP_DigestSignInit ,
+.Fn EVP_DigestSignUpdate ,
+and

+.Sh DESCRIPTION
+The EVP signature routines are a high level interface to digital
+signatures.
+.Pp
+.Fn EVP_DigestVerifyInit
+sets up verification context
+.Fa ctx
+to use digest
+.Fa type
+from
+.Vt ENGINE
+.Fa e
+and public key
+.Fa pkey .
+.Fa ctx
+must be initialized with
+.Xr EVP_MD_CTX_init 3
+before calling this function.
+If
+.Fa pctx
+is not
+.Dv NULL ,
+the
+.Vt EVP_PKEY_CTX
+of the verification operation will be written to
+.Pf * Fa pctx :
+this can be used to set alternative verification options.
+.Pp
+.Fn EVP_DigestVerifyUpdate
+hashes
+.Fa cnt
+bytes of data at
+.Fa d
+into the verification context
+.Fa ctx .
+This function can be called several times on the same
+.Fa ctx
+to include additional data.
+This function is currently implemented using a macro.
+.Pp
+.Fn EVP_DigestVerifyFinal
+verifies the data in
+.Fa ctx
+against the signature in
+.Fa sig
+of length
+.Fa siglen .
+.Pp
+The EVP interface to digital signatures should almost always be
+used in preference to the low level interfaces.
+This is because the code then becomes transparent to the algorithm used
+and much more flexible.
+.Pp
+In previous versions of OpenSSL, there was a link between message digest
+types and public key algorithms.
+This meant that "clone" digests such as
+.Xr EVP_dss1 3
+needed to be used to sign using SHA1 and DSA.
+This is no longer necessary and the use of clone digest is now
+discouraged.
+.Pp
+The call to
+.Fn EVP_DigestVerifyFinal
+internally finalizes a copy of the digest context.
+This means that calls to
+.Xr EVP_VerifyUpdate 3
+and
+.Xr EVP_VerifyFinal 3
+can be called later to digest and verify additional data.
+.Pp
+Since only a copy of the digest context is ever finalized, the context
+must be cleaned up after use by calling
+.Xr EVP_MD_CTX_cleanup 3
+or a memory leak will occur.
+.Sh RETURN VALUES
+.Fn EVP_DigestVerifyInit
+and
+.Fn EVP_DigestVerifyUpdate
+return 1 for success and 0 or a negative value for failure.
+In particular a return value of -2 indicates the operation is not
+supported by the public key algorithm.
+.Pp
+Unlike other functions, the return value 0 from
+.Fn EVP_DigestVerifyFinal
+only indicates that the signature did not verify successfully.
+That is it did not match the original data or the signature was of
+invalid form.
+It is not an indication of a more serious error.
+.Pp
+The error codes can be obtained from
+.Xr ERR_get_error 3 .

+.Sh DESCRIPTION
+The EVP cipher routines are a high level interface to certain symmetric
+ciphers.
+.Pp
+.Fn EVP_CIPHER_CTX_init
+initializes the cipher context
+.Fa ctx .
+.Pp
+.Fn EVP_EncryptInit_ex
+sets up the cipher context
+.Fa ctx
+for encryption with cipher
+.Fa type
+from
+.Vt ENGINE
+.Fa impl .
+.Fa ctx
+must be initialized before calling this function.
+.Fa type
+is normally supplied by a function such as
+.Fn EVP_aes_256_cbc .
+If
+.Fa impl
+is
+.Dv NULL ,
+then the default implementation is used.
+.Fa key
+is the symmetric key to use and
+.Fa iv
+is the IV to use (if necessary), the actual number of bytes used for the
+key and IV depends on the cipher.
+It is possible to set all parameters to
+.Dv NULL
+except
+.Fa type
+in an initial call and supply the remaining parameters in subsequent
+calls, all of which have
+.Fa type
+set to
+.Dv NULL .
+This is done when the default cipher parameters are not appropriate.
+.Pp
+.Fn EVP_EncryptUpdate
+encrypts
+.Fa inl
+bytes from the buffer
+.Fa in
+and writes the encrypted version to
+.Fa out .
+This function can be called multiple times to encrypt successive blocks
+of data.
+The amount of data written depends on the block alignment of the
+encrypted data: as a result the amount of data written may be anything
+from zero bytes to (inl + cipher_block_size - 1) so
+.Fa outl
+should contain sufficient room.
+The actual number of bytes written is placed in
+.Fa outl .
+.Pp
+If padding is enabled (the default) then
+.Fn EVP_EncryptFinal_ex
+encrypts the "final" data, that is any data that remains in a partial
+block.
+It uses NOTES (aka PKCS padding).
+The encrypted final data is written to
+.Fa out
+which should have sufficient space for one cipher block.
+The number of bytes written is placed in
+.Fa outl .
+After this function is called the encryption operation is finished and
+no further calls to
+.Fn EVP_EncryptUpdate
+should be made.
+.Pp
+If padding is disabled then
+.Fn EVP_EncryptFinal_ex
+will not encrypt any more data and it will return an error if any data
+remains in a partial block: that is if the total data length is not a
+multiple of the block size.
+.Pp
+.Fn EVP_DecryptInit_ex ,
+.Fn EVP_DecryptUpdate ,
+and
+.Fn EVP_DecryptFinal_ex
+are the corresponding decryption operations.
+.Fn EVP_DecryptFinal
+will return an error code if padding is enabled and the final block is
+not correctly formatted.
+The parameters and restrictions are identical to the encryption
+operations except that if padding is enabled the decrypted data buffer
+.Fa out
+passed to
+.Fn EVP_DecryptUpdate
+should have sufficient room for (inl + cipher_block_size) bytes
+unless the cipher block size is 1 in which case
+.Fa inl
+bytes is sufficient.
+.Pp
+.Fn EVP_CipherInit_ex ,
+.Fn EVP_CipherUpdate ,
+and
+.Fn EVP_CipherFinal_ex
+are functions that can be used for decryption or encryption.
+The operation performed depends on the value of the
+.Fa enc
+parameter.
+It should be set to 1 for encryption, 0 for decryption and -1 to leave
+the value unchanged (the actual value of
+.Fa enc
+being supplied in a previous call).
+.Pp
+.Fn EVP_CIPHER_CTX_cleanup
+clears all information from a cipher context and free up any allocated
+memory associate with it.
+It should be called after all operations using a cipher are complete so
+sensitive information does not remain in memory.
+.Pp
+.Fn EVP_EncryptInit ,
+.Fn EVP_DecryptInit ,
+and
+.Fn EVP_CipherInit
+behave in a similar way to
+.Fn EVP_EncryptInit_ex ,
+.Fn EVP_DecryptInit_ex ,
+and
+.Fn EVP_CipherInit_ex
+except the
+.Fa ctx
+parameter does not need to be initialized and they always use the
+default cipher implementation.
+.Pp
+.Fn EVP_EncryptFinal ,
+.Fn EVP_DecryptFinal ,
+and
+.Fn EVP_CipherFinal
+are identical to
+.Fn EVP_EncryptFinal_ex ,
+.Fn EVP_DecryptFinal_ex ,
+and
+.Fn EVP_CipherFinal_ex .
+In previous releases of OpenSSL, they also used to clean up the
+.Fa ctx ,
+but this is no longer done and
+.Fn EVP_CIPHER_CTX_cleanup
+must be called to free any context resources.
+.Pp
+.Fn EVP_get_cipherbyname ,
+.Fn EVP_get_cipherbynid ,
+and
+.Fn EVP_get_cipherbyobj
+return an
+.Vt EVP_CIPHER
+structure when passed a cipher name, a NID or an
+.Vt ASN1_OBJECT
+structure.
+.Pp
+.Fn EVP_CIPHER_nid
+and
+.Fn EVP_CIPHER_CTX_nid
+return the NID of a cipher when passed an
+.Vt EVP_CIPHER
+or
+.Vt EVP_CIPHER_CTX
+structure.
+The actual NID value is an internal value which may not have a
+corresponding OBJECT IDENTIFIER.
+.Pp
+.Fn EVP_CIPHER_CTX_set_padding
+enables or disables padding.
+By default encryption operations are padded using standard block padding
+and the padding is checked and removed when decrypting.
+If the
+.Sy padding
+parameter is zero, then no padding is performed, the total amount of data
+encrypted or decrypted must then be a multiple of the block size or an
+error will occur.
+.Pp
+.Fn EVP_CIPHER_key_length
+and
+.Fn EVP_CIPHER_CTX_key_length
+return the key length of a cipher when passed an
+.Vt EVP_CIPHER
+or
+.Vt EVP_CIPHER_CTX
+structure.
+The constant
+.Dv EVP_MAX_KEY_LENGTH
+is the maximum key length for all ciphers.
+Note: although
+.Fn EVP_CIPHER_key_length
+is fixed for a given cipher, the value of
+.Fn EVP_CIPHER_CTX_key_length
+may be different for variable key length ciphers.
+.Pp
+.Fn EVP_CIPHER_CTX_set_key_length
+sets the key length of the cipher ctx.
+If the cipher is a fixed length cipher, then attempting to set the key
+length to any value other than the fixed value is an error.
+.Pp
+.Fn EVP_CIPHER_iv_length
+and
+.Fn EVP_CIPHER_CTX_iv_length
+return the IV length of a cipher when passed an
+.Vt EVP_CIPHER
+or
+.Vt EVP_CIPHER_CTX .
+It will return zero if the cipher does not use an IV.
+The constant
+.Dv EVP_MAX_IV_LENGTH
+is the maximum IV length for all ciphers.
+.Pp
+.Fn EVP_CIPHER_block_size
+and
+.Fn EVP_CIPHER_CTX_block_size
+return the block size of a cipher when passed an
+.Vt EVP_CIPHER
+or
+.Vt EVP_CIPHER_CTX
+structure.
+The constant
+.Dv EVP_MAX_IV_LENGTH
+is also the maximum block length for all ciphers.
+.Pp
+.Fn EVP_CIPHER_type
+and
+.Fn EVP_CIPHER_CTX_type
+return the type of the passed cipher or context.
+This "type" is the actual NID of the cipher OBJECT IDENTIFIER as such it
+ignores the cipher parameters and 40 bit RC2 and 128 bit RC2 have the
+same NID. If the cipher does not have an object identifier or does not
+have ASN1 support this function will return
+.Dv NID_undef .
+.Pp
+.Fn EVP_CIPHER_CTX_cipher
+returns the
+.Vt EVP_CIPHER
+structure when passed an
+.Vt EVP_CIPHER_CTX
+structure.
+.Pp
+.Fn EVP_CIPHER_mode
+and
+.Fn EVP_CIPHER_CTX_mode
+return the block cipher mode:
+.Dv EVP_CIPH_ECB_MODE ,
+.Dv EVP_CIPH_CBC_MODE ,
+.Dv EVP_CIPH_CFB_MODE ,
+or
+.Dv EVP_CIPH_OFB_MODE .
+If the cipher is a stream cipher then
+.Dv EVP_CIPH_STREAM_CIPHER
+is returned.
+.Pp
+.Fn EVP_CIPHER_param_to_asn1
+sets the AlgorithmIdentifier "parameter" based on the passed cipher.
+This will typically include any parameters and an IV.
+The cipher IV (if any) must be set when this call is made.
+This call should be made before the cipher is actually "used" (before any
+.Fn EVP_EncryptUpdate ,
+.Fn EVP_DecryptUpdate
+calls for example).
+This function may fail if the cipher does not have any ASN1 support.
+.Pp
+.Fn EVP_CIPHER_asn1_to_param
+sets the cipher parameters based on an ASN1 AlgorithmIdentifier
+"parameter".
+The precise effect depends on the cipher.
+In the case of RC2, for example, it will set the IV and effective
+key length.
+This function should be called after the base cipher type is set but
+before the key is set.
+For example
+.Fn EVP_CipherInit
+will be called with the IV and key set to
+.Dv NULL ,
+.Fn EVP_CIPHER_asn1_to_param
+will be called and finally
+.Fn EVP_CipherInit
+again with all parameters except the key set to
+.Dv NULL .
+It is possible for this function to fail if the cipher does not
+have any ASN1 support or the parameters cannot be set (for example
+the RC2 effective key length is not supported).
+.Pp
+.Fn EVP_CIPHER_CTX_ctrl
+allows various cipher specific parameters to be determined and set.
+Currently only the RC2 effective key length and the number of rounds of
+RC5 can be set.
+.Sh RETURN VALUES
+.Fn EVP_EncryptInit_ex ,
+.Fn EVP_EncryptUpdate ,
+and
+.Fn EVP_EncryptFinal_ex
+return 1 for success and 0 for failure.
+.Pp
+.Fn EVP_DecryptInit_ex
+and
+.Fn EVP_DecryptUpdate
+return 1 for success and 0 for failure.
+.Fn EVP_DecryptFinal_ex
+returns 0 if the decrypt failed or 1 for success.
+.Pp
+.Fn EVP_CipherInit_ex
+and
+.Fn EVP_CipherUpdate
+return 1 for success and 0 for failure.
+.Fn EVP_CipherFinal_ex
+returns 0 for a decryption failure or 1 for success.
+.Pp
+.Fn EVP_CIPHER_CTX_cleanup
+returns 1 for success and 0 for failure.
+.Pp
+.Fn EVP_get_cipherbyname ,
+.Fn EVP_get_cipherbynid ,
+and
+.Fn EVP_get_cipherbyobj
+return an
+.Vt EVP_CIPHER
+structure or
+.Dv NULL
+on error.
+.Pp
+.Fn EVP_CIPHER_nid
+and
+.Fn EVP_CIPHER_CTX_nid
+return a NID.
+.Pp
+.Fn EVP_CIPHER_block_size
+and
+.Fn EVP_CIPHER_CTX_block_size
+return the block size.
+.Pp
+.Fn EVP_CIPHER_key_length
+and
+.Fn EVP_CIPHER_CTX_key_length
+return the key length.
+.Pp
+.Fn EVP_CIPHER_CTX_set_padding
+always returns 1.
+.Pp
+.Fn EVP_CIPHER_iv_length
+and
+.Fn EVP_CIPHER_CTX_iv_length
+return the IV length or zero if the cipher does not use an IV.
+.Pp
+.Fn EVP_CIPHER_type
+and
+.Fn EVP_CIPHER_CTX_type
+return the NID of the cipher's OBJECT IDENTIFIER or
+.Dv NID_undef
+if it has no defined OBJECT IDENTIFIER.
+.Pp
+.Fn EVP_CIPHER_CTX_cipher
+returns an
+.Vt EVP_CIPHER
+structure.
+.Pp
+.Fn EVP_CIPHER_param_to_asn1
+and
+.Fn EVP_CIPHER_asn1_to_param
+return 1 for success or 0 for failure.
+.Pp
+Where possible the EVP interface to symmetric ciphers should be
+used in preference to the low level interfaces.
+This is because the code then becomes transparent to the cipher used and
+much more flexible.
+.Pp
+PKCS padding works by adding n padding bytes of value n to make the
+total length of the encrypted data a multiple of the block size.
+Padding is always added so if the data is already a multiple of the
+block size n will equal the block size.
+For example if the block size is 8 and 11 bytes are to be encrypted then
+5 padding bytes of value 5 will be added.
+.Pp
+When decrypting the final block is checked to see if it has the correct
+form.
+.Pp
+Although the decryption operation can produce an error if padding is
+enabled, it is not a strong test that the input data or key is correct.
+A random block has better than 1 in 256 chance of being of the correct
+format and problems with the input data earlier on will not produce a
+final decrypt error.
+.Pp
+If padding is disabled then the decryption operation will always succeed
+if the total amount of data decrypted is a multiple of the block size.

+The functions
+.Fn EVP_EncryptInit ,
+.Fn EVP_EncryptFinal ,

+.Fn EVP_CipherInit ,

+and

+only refer to the internal ciphers with default key lengths.
+If custom ciphers exceed these values the results are unpredictable.
+This is because it has become standard practice to define a generic key
+as a fixed unsigned char array containing
+.Dv EVP_MAX_KEY_LENGTH
+bytes.
+.Pp
+The ASN1 code is incomplete (and sometimes inaccurate) it has only been
+tested for certain common S/MIME ciphers (RC2, DES, triple DES) in CBC

+.Sh DESCRIPTION
+The function
+.Fn EVP_PKEY_CTX_ctrl
+sends a control operation to the context
+.Fa ctx .
+The key type used must match
+.Fa keytype
+if it is not -1.
+The parameter
+.Fa optype
+is a mask indicating which operations the control can be applied to.
+The control command is indicated in
+.Fa cmd
+and any additional arguments in
+.Fa p1
+and
+.Fa p2 .
+.Pp
+Applications will not normally call
+.Fn EVP_PKEY_CTX_ctrl
+directly but will instead call one of the algorithm specific macros
+below.
+.Pp
+The function
+.Fn EVP_PKEY_CTX_ctrl_str
+allows an application to send an algorithm specific control operation to
+a context
+.Fa ctx
+in string form.
+This is intended to be used for options specified on the command line or
+in text files.
+The commands supported are documented in the
+.Xr openssl 1
+utility command line pages for the option
+.Fl pkeyopt
+which is supported by the
+.Cm pkeyutl ,
+.Cm genpkey ,
+and
+.Cm req
+commands.
+.Pp
+All the remaining "functions" are implemented as macros.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_signature_md
+macro sets the message digest type used in a signature.
+It can be used with any public key algorithm supporting signature
+operations.
+.Pp
+The macro
+.Fn EVP_PKEY_CTX_set_rsa_padding
+sets the RSA padding mode for
+.Fa ctx .
+The
+.Fa pad
+parameter can take the value
+.Dv RSA_PKCS1_PADDING
+for PKCS#1 padding,
+.Dv RSA_SSLV23_PADDING
+for SSLv23 padding,
+.Dv RSA_NO_PADDING
+for no padding,
+.Dv RSA_PKCS1_OAEP_PADDING
+for OAEP padding (encrypt and decrypt only),
+.Dv RSA_X931_PADDING
+for X9.31 padding (signature operations only) and
+.Dv RSA_PKCS1_PSS_PADDING
+(sign and verify only).
+.Pp
+Two RSA padding modes behave differently if
+.Fn EVP_PKEY_CTX_set_signature_md
+is used.
+If this macro is called for PKCS#1 padding, the plaintext buffer is an
+actual digest value and is encapsulated in a DigestInfo structure
+according to PKCS#1 when signing and this structure is expected (and
+stripped off) when verifying.
+If this control is not used with RSA and PKCS#1 padding then the
+supplied data is used directly and not encapsulated.
+In the case of X9.31 padding for RSA the algorithm identifier byte is
+added or checked and removed if this control is called.
+If it is not called then the first byte of the plaintext buffer is
+expected to be the algorithm identifier byte.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_rsa_pss_saltlen
+macro sets the RSA PSS salt length to
+.Fa len
+as its name implies it is only supported for PSS padding.
+Two special values are supported: -1 sets the salt length to the digest
+length.
+When signing -2 sets the salt length to the maximum permissible value.
+When verifying -2 causes the salt length to be automatically determined
+based on the PSS block structure.
+If this macro is not called a salt length value of -2 is used by
+default.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_rsa_rsa_keygen_bits
+macro sets the RSA key length for RSA key generation to
+.Fa mbits .
+If not specified, 1024 bits is used.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_rsa_keygen_pubexp
+macro sets the public exponent value for RSA key generation to
+.Fa pubexp .
+Currently, it should be an odd integer.
+The
+.Fa pubexp
+pointer is used internally by this function, so it should not be modified
+or freed after the call.
+If this macro is not called, then 65537 is used.
+.Pp
+The macro
+.Fn EVP_PKEY_CTX_set_dsa_paramgen_bits
+sets the number of bits used for DSA parameter generation to
+.Fa nbits .
+If not specified, 1024 is used.
+.Pp
+The macro
+.Fn EVP_PKEY_CTX_set_dh_paramgen_prime_len
+sets the length of the DH prime parameter
+.Fa len
+for DH parameter generation.
+If this macro is not called, then 1024 is used.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_dh_paramgen_generator
+macro sets DH generator to
+.Fa gen
+for DH parameter generation.
+If not specified, 2 is used.
+.Pp
+The
+.Fn EVP_PKEY_CTX_set_ec_paramgen_curve_nid
+sets the EC curve for EC parameter generation to
+.Fa nid .
+For EC parameter generation, this macro must be called or an error occurs
+because there is no default curve.
+.Sh RETURN VALUES
+.Fn EVP_PKEY_CTX_ctrl
+and its macros return a positive value for success and 0 or a negative
+value for failure.
+In particular, a return value of -2 indicates the operation is not
+supported by the public key algorithm.

+.Sh DESCRIPTION
+The
+.Fn EVP_PKEY_keygen_init
+function initializes a public key algorithm context using key
+.Fa ctx->pkey
+for a key generation operation.
+.Pp
+The
+.Fn EVP_PKEY_keygen
+function performs a key generation operation, the generated key is
+written to
+.Fa ppkey .
+.Pp
+The functions
+.Fn EVP_PKEY_paramgen_init
+and
+.Fn EVP_PKEY_paramgen
+are similar except parameters are generated.
+.Pp
+The function
+.Fn EVP_PKEY_CTX_set_cb
+sets the key or parameter generation callback to
+.Fa cb .
+The function
+.Fn EVP_PKEY_CTX_get_cb
+returns the key or parameter generation callback.
+.Pp
+The function
+.Fn EVP_PKEY_CTX_get_keygen_info
+returns parameters associated with the generation operation.
+If
+.Fa idx
+is -1, the total number of parameters available is returned.
+Any non negative value returns the value of that parameter.
+.Fn EVP_PKEY_CTX_get_keygen_info
+with a non-negative value for
+.Fa idx
+should only be called within the generation callback.
+.Pp
+If the callback returns 0, then the key generation operation is aborted
+and an error occurs.
+This might occur during a time consuming operation where a user clicks
+on a "cancel" button.
+.Pp
+The functions
+.Fn EVP_PKEY_CTX_set_app_data
+and
+.Fn EVP_PKEY_CTX_get_app_data
+set and retrieve an opaque pointer.
+This can be used to set some application defined value which can be
+retrieved in the callback: for example a handle which is used to update
+a "progress dialog".
+.Pp
+After the call to
+.Fn EVP_PKEY_keygen_init
+or
+.Fn EVP_PKEY_paramgen_init ,
+algorithm specific control operations can be performed to set any
+appropriate parameters for the operation.
+.Pp
+The functions
+.Fn EVP_PKEY_keygen
+and
+.Fn EVP_PKEY_paramgen
+can be called more than once on the same context if several operations
+are performed using the same parameters.
+.Pp
+The meaning of the parameters passed to the callback will depend on the
+algorithm and the specific implementation of the algorithm.
+Some might not give any useful information at all during key or
+parameter generation.
+Others might not even call the callback.
+.Pp
+The operation performed by key or parameter generation depends on the
+algorithm used.
+In some cases (e.g. EC with a supplied named curve) the "generation"
+option merely sets the appropriate fields in an
+.Vt EVP_PKEY
+structure.
+.Pp
+In OpenSSL, an
+.Vt EVP_PKEY
+structure containing a private key also contains the public key
+components and parameters (if any).
+An OpenSSL private key is equivalent to what some libraries call a "key
+pair".
+A private key can be used in functions which require the use of a public
+key or parameters.
+.Sh RETURN VALUES
+.Fn EVP_PKEY_keygen_init ,
+.Fn EVP_PKEY_paramgen_init ,
+.Fn EVP_PKEY_keygen ,
+and
+.Fn EVP_PKEY_paramgen
+return 1 for success and 0 or a negative value for failure.
+In particular, a return value of -2 indicates the operation is not
+supported by the public key algorithm.

+The EVP envelope routines are a high level interface to envelope
+encryption.
+They generate a random key and IV (if required) then "envelope" it by
+using public key encryption.
+Data can then be encrypted using this key.
+.Pp
+.Fn EVP_SealInit
+initializes a cipher context
+.Fa ctx
+for encryption with cipher
+.Fa type
+using a random secret key and IV.
+.Fa type
+is normally supplied by a function such as
+.Fn EVP_aes_256_cbc 3 ;
+see
+.Xr EVP_EncryptInit 3
+for details.
+The secret key is encrypted using one or more public keys.
+This allows the same encrypted data to be decrypted using any of
+the corresponding private keys.
+.Fa ek
+is an array of buffers where the public key encrypted secret key will be
+written.
+Each buffer must contain enough room for the corresponding encrypted
+key: that is
+.Fa ek[i]
+must have room for
+.Fn EVP_PKEY_size pubk[i]
+bytes.
+The actual size of each encrypted secret key is written to the array
+.Fa ekl .
+.Fa pubk
+is an array of
+.Fa npubk
+public keys.
+.Pp
+The
+.Fa iv
+parameter is a buffer where the generated IV is written to.
+It must contain enough room for the corresponding cipher's IV, as
+determined by (for example)
+.Fn EVP_CIPHER_iv_length type .
+.Pp

+The public key must be RSA because it is the only OpenSSL public key

+Envelope encryption is the usual method of using public key encryption
+on large amounts of data.
+This is because public key encryption is slow but symmetric encryption
+is fast.
+So symmetric encryption is used for bulk encryption and the small random

+.Pp
+It is possible to call

+.Dt EVP 3
+.Os
+.Sh NAME
+.Nm evp
+.Nd high-level cryptographic functions
+.Sh SYNOPSIS
+.In openssl/evp.h
+.Sh DESCRIPTION
+The EVP library provides a high-level interface to cryptographic
+functions.
+.Pp
+.Xr EVP_SealInit 3
+and
+.Xr EVP_OpenInit 3
+provide public key encryption and decryption to implement digital
+"envelopes".
+.Pp
+The
+.Xr EVP_DigestSignInit 3
+and
+.Xr EVP_DigestVerifyInit 3
+functions implement digital signatures and Message Authentication Codes
+(MACs).
+Also see the older
+.Xr EVP_SignInit 3
+and
+.Xr EVP_VerifyInit 3
+functions.
+.Pp
+Symmetric encryption is available with the
+.Xr EVP_EncryptInit 3
+functions.
+The
+.Xr EVP_DigestInit 3
+functions provide message digests.
+.Pp
+Authenticated encryption with additional data (AEAD) is available with
+the
+.Xr EVP_AEAD_CTX_init 3
+functions.
+.Pp
+The
+.Fn EVP_PKEY_*
+functions provide a high level interface to asymmetric algorithms.
+To create a new
+.Vt EVP_PKEY ,
+see
+.Xr EVP_PKEY_new 3 .
+.Vt EVP_PKEY Ns s
+can be associated with a private key of a particular algorithm
+by using the functions described in the
+.Xr EVP_PKEY_set1_RSA 3
+page, or new keys can be generated using
+.Xr EVP_PKEY_keygen 3 .
+.Vt EVP_PKEY Ns s
+can be compared using
+.Xr EVP_PKEY_cmp 3
+or printed using
+.Xr EVP_PKEY_print_private 3 .
+.Pp
+The
+.Fn EVP_PKEY_*
+functions support the full range of asymmetric algorithm operations:
+.Bl -bullet
+.It
+For key agreement, see
+.Xr EVP_PKEY_derive 3 .
+.It
+For signing and verifying, see
+.Xr EVP_PKEY_sign 3 ,
+.Xr EVP_PKEY_verify 3 ,
+and
+.Xr EVP_PKEY_verify_recover 3 .
+However, note that these functions do not perform a digest of the
+data to be signed.
+Therefore normally you would use the
+.Xr EVP_DigestSignInit 3
+functions for this purpose.
+.It
+For encryption and decryption see
+.Xr EVP_PKEY_encrypt 3
+and
+.Xr EVP_PKEY_decrypt 3 ,
+respectively.
+However, note that these functions perform encryption and decryption only.
+As public key encryption is an expensive operation, normally you
+would wrap an encrypted message in a digital envelope using the
+.Xr EVP_SealInit 3
+and
+.Xr EVP_OpenInit 3
+functions.
+.El
+.Pp
+The
+.Xr EVP_BytesToKey 3
+function provides some limited support for password based encryption.
+Careful selection of the parameters will provide a PKCS#5 PBKDF1
+compatible implementation.
+However, new applications should typically not use this (preferring, for
+example, PBKDF2 from PCKS#5).
+.Pp
+Algorithms are loaded with
+.Xr OpenSSL_add_all_algorithms 3 .
+.Pp
+All the symmetric algorithms (ciphers), digests and asymmetric
+algorithms (public key algorithms) can be replaced by
+.Xr engine 3
+modules providing alternative implementations.
+If
+.Vt ENGINE
+implementations of ciphers or digests are registered as defaults,
+then the various EVP functions will automatically use those
+implementations in preference to built in software implementations.
+For more information, consult the
+.Xr engine 3
+manual page.
+.Pp
+Although low level algorithm specific functions exist for many
+algorithms, their use is discouraged.
+They cannot be used with an
+.Vt ENGINE ,
+and
+.Vt ENGINE
+versions of new algorithms cannot be accessed using the low level
+functions.
+Using them also makes code harder to adapt to new algorithms, some
+options are not cleanly supported at the low level, and some
+operations are more efficient using the high level interfaces.
