+
+EVP_DigestSignInit, EVP_DigestSignUpdate, EVP_DigestSignFinal - EVP signing functions
+
+=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
+usig 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.
+
+For some key types and parameters the random number generator must be seeded
+or the operation will fail. 
+
+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 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_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 genration 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.

+
+=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 genration 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

+
+=head1 DESCRIPTION
+
+The EVP_PKEY_keygen_init() function initializes a public key algorithm
+context using key B<pkey> for a key genration 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 genration 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 specifiic 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.

+
+ PKCS7_SIGNER_INFO *PKCS7_sign_add_signer(PKCS7 *p7, X509 *signcert, EVP_PKEY *pkey, const EVP_MD *md, int flags);
+
+
+=head1 DESCRIPTION
+
+PKCS7_sign_add_signer() adds a signer with certificate B<signcert> and private
+key B<pkey> using message digest B<md> to a PKCS7 signed data structure
+B<p7>.
+
+The PKCS7 structure should be obtained from an initial call to PKCS7_sign()
+with the flag B<PKCS7_PARTIAL> set or in the case or re-signing a valid PKCS7
+signed data structure.
+
+If the B<md> parameter is B<NULL> then the default digest for the public
+key algorithm will be used.
+
+Unless the B<PKCS7_REUSE_DIGEST> flag is set the returned PKCS7 structure
+is not complete and must be finalized either by streaming (if applicable) or
+a call to PKCS7_final().
+
+
+=head1 NOTES
+
+The main purpose of this function is to provide finer control over a PKCS#7
+signed data structure where the simpler PKCS7_sign() function defaults are
+not appropriate. For example if multiple signers or non default digest
+algorithms are needed.
+
+Any of the following flags (ored together) can be passed in the B<flags>
+parameter.
+
+If B<PKCS7_REUSE_DIGEST> is set then an attempt is made to copy the content
+digest value from the PKCS7 struture: to add a signer to an existing structure.
+An error occurs if a matching digest value cannot be found to copy. The
+returned PKCS7 structure will be valid and finalized when this flag is set.
+
+If B<PKCS7_PARTIAL> is set in addition to B<PKCS7_REUSE_DIGEST> then the 
+B<PKCS7_SIGNER_INO> structure will not be finalized so additional attributes
+can be added. In this case an explicit call to PKCS7_SIGNER_INFO_sign() is
+needed to finalize it.
+
+If B<PKCS7_NOCERTS> is set the signer's certificate will not be included in the
+PKCS7 structure, the signer's certificate must still be supplied in the
+B<signcert> parameter though. This can reduce the size of the signature if the
+signers certificate can be obtained by other means: for example a previously
+signed message.
+
+The signedData structure includes several PKCS#7 autenticatedAttributes
+including the signing time, the PKCS#7 content type and the supported list of
+ciphers in an SMIMECapabilities attribute. If B<PKCS7_NOATTR> is set then no
+authenticatedAttributes will be used. If B<PKCS7_NOSMIMECAP> is set then just
+the SMIMECapabilities are omitted.
+
+If present the SMIMECapabilities attribute indicates support for the following
+algorithms: triple DES, 128 bit RC2, 64 bit RC2, DES and 40 bit RC2. If any of
+these algorithms is disabled then it will not be included.
+

+
+=head1 SYNOPSIS
+
+ #include <openssl/cms.h>
+
+ CMS_ContentInfo *SMIME_read_CMS(BIO *in, BIO **bcont);
+
+=head1 DESCRIPTION
+
+SMIME_read_CMS() parses a message in S/MIME format.
+
+B<in> is a BIO to read the message from.
+
+If cleartext signing is used then the content is saved in a memory bio which is
+written to B<*bcont>, otherwise B<*bcont> is set to NULL.
+
+The parsed CMS_ContentInfo structure is returned or NULL if an
+error occurred.
+
+=head1 NOTES
+
+If B<*bcont> is not NULL then the message is clear text signed. B<*bcont> can
+then be passed to CMS_verify() with the B<CMS_DETACHED> flag set.
+
+Otherwise the type of the returned structure can be determined
+using CMS_get0_type().
+
+To support future functionality if B<bcont> is not NULL B<*bcont> should be
+initialized to NULL. For example:
+
+ BIO *cont = NULL;
+ CMS_ContentInfo *cms;
+
+ cms = SMIME_read_CMS(in, &cont);
+
+=head1 BUGS
+
+The MIME parser used by SMIME_read_CMS() is somewhat primitive.  While it will
+handle most S/MIME messages more complex compound formats may not work.
+
+The parser assumes that the CMS_ContentInfo structure is always base64 encoded
+and will not handle the case where it is in binary format or uses quoted
+printable format.
+
+The use of a memory BIO to hold the signed content limits the size of message
+which can be processed due to memory restraints: a streaming single pass option
+should be available.
+
+=head1 RETURN VALUES
+
+SMIME_read_CMS() returns a valid B<CMS_ContentInfo> structure or B<NULL>
+if an error occurred. The error can be obtained from ERR_get_error(3).

+
+SMIME_write_CMS() adds the appropriate MIME headers to a CMS

+
+B<out> is the BIO to write the data to. B<cms> is the appropriate

+
+If the B<CMS_TEXT> flag is set MIME headers for type B<text/plain> are added to

+
+If the B<CMS_STREAM> flag is set streaming is performed. This flag should only
+be set if B<CMS_STREAM> was also set in the previous call to a CMS_ContentInfo
+creation function.
+
+If cleartext signing is being used and B<CMS_STREAM> not set then the data must
+be read twice: once to compute the signature in CMS_sign() and once to output

+
+If streaming is performed the content is output in BER format using indefinite
+length constructed encoding except in the case of signed data with detached

+=head1 DESCRIPTION
+
+These functions are typically called after X509_verify_cert() has indicated
+an error or in a verification callback to determine the nature of an error.
+
+X509_STORE_CTX_get_error() returns the error code of B<ctx>, see
+the B<ERROR CODES> section for a full description of all error codes.
+
+X509_STORE_CTX_set_error() sets the error code of B<ctx> to B<s>. For example
+it might be used in a verification callback to set an error based on additional
+checks.
+
+X509_STORE_CTX_get_error_depth() returns the B<depth> of the error. This is a
+non-negative integer representing where in the certificate chain the error
+occurred. If it is zero it occured in the end entity certificate, one if
+it is the certificate which signed the end entity certificate and so on.
+
+X509_STORE_CTX_get_current_cert() returns the certificate in B<ctx> which
+caused the error or B<NULL> if no certificate is relevant.
+
+X509_STORE_CTX_get1_chain() returns a complete validate chain if a previous
+call to X509_verify_cert() is successful. If the call to X509_verify_cert()
+is B<not> successful the returned chain may be incomplete or invalid. The
+returned chain persists after the B<ctx> structure is freed, when it is
+no longer needed it should be free up using:
+
+  sk_X509_pop_free(chain, X509_free);
+
+X509_verify_cert_error_string() returns a human readable error string for
+verification error B<n>.
+
+=head1 RETURN VALUES
+
+X509_STORE_CTX_get_error() returns B<X509_V_OK> or an error code.
+
+X509_STORE_CTX_get_error_depth() returns a non-negative error depth.
+
+X509_STORE_CTX_get_current_cert() returns the cerificate which caused the
+error or B<NULL> if no certificate is relevant to the error.
+
+X509_verify_cert_error_string() returns a human readable error string for

+
+=head1 DESCRIPTION
+
+These functions initialise an B<X509_STORE_CTX> structure for subsequent use
+by X509_verify_cert().
+
+X509_STORE_CTX_new() returns a newly initialised B<X509_STORE_CTX> structure.
+
+X509_STORE_CTX_cleanup() internally cleans up an B<X509_STORE_CTX> structure.
+The context can then be reused with an new call to X509_STORE_CTX_init().
+
+X509_STORE_CTX_free() completely frees up B<ctx>. After this call B<ctx>
+is no longer valid.
+
+X509_STORE_CTX_init() sets up B<ctx> for a subsequent verification operation.
+The trusted certificate store is set to B<store>, the end entity certificate
+to be verified is set to B<x509> and a set of additional certificates (which
+will be untrusted but may be used to build the chain) in B<chain>. Any or
+all of the B<store>, B<x509> and B<chain> parameters can be B<NULL>.
+
+X509_STORE_CTX_trusted_stack() sets the set of trusted certificates of B<ctx>
+to B<sk>. This is an alternative way of specifying trusted certificates 
+instead of using an B<X509_STORE>.
+
+X509_STORE_CTX_set_cert() sets the certificate to be vertified in B<ctx> to
+B<x>.
+
+X509_STORE_CTX_set_chain() sets the additional certificate chain used by B<ctx>
+to B<sk>.
+
+X509_STORE_CTX_set0_crls() sets a set of CRLs to use to aid certificate
+verification to B<sk>. These CRLs will only be used if CRL verification is
+enabled in the associated B<X509_VERIFY_PARAM> structure. This might be
+used where additional "useful" CRLs are supplied as part of a protocol,
+for example in a PKCS#7 structure.
+
+X509_VERIFY_PARAM *X509_STORE_CTX_get0_param() retrieves an intenal pointer
+to the verification parameters associated with B<ctx>.
+
+X509_STORE_CTX_set0_param() sets the intenal verification parameter pointer
+to B<param>. After this call B<param> should not be used.
+
+X509_STORE_CTX_set_default() looks up and sets the default verification
+method to B<name>. This uses the function X509_VERIFY_PARAM_lookup() to
+find an appropriate set of parameters from B<name>.
+
+=head1 NOTES
+
+The certificates and CRLs in a store are used internally and should B<not>
+be freed up until after the associated B<X509_STORE_CTX> is freed. Legacy
+applications might implicitly use an B<X509_STORE_CTX> like this:
+
+  X509_STORE_CTX ctx;
+  X509_STORE_CTX_init(&ctx, store, cert, chain);
+
+this is B<not> recommended in new applications they should instead do:
+
+  X509_STORE_CTX *ctx;
+  ctx = X509_STORE_CTX_new();
+  if (ctx == NULL)
+        /* Bad error */
+  X509_STORE_CTX_init(ctx, store, cert, chain);
+
+=head1 BUGS
+
+The certificates and CRLs in a context are used internally and should B<not>
+be freed up until after the associated B<X509_STORE_CTX> is freed. Copies
+should be made or reference counts increased instead.
+

+
+X509_STORE_CTX_new() returns an newly allocates context or B<NULL> is an
+error occurred.
+
+X509_STORE_CTX_init() returns 1 for success or 0 if an error occurred.

+=head1 NAME
+
+X509_STORE_CTX_set_verify_cb - set verification callback
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509_vfy.h>
+
+ void X509_STORE_CTX_set_verify_cb(X509_STORE_CTX *ctx,
+                                int (*verify_cb)(int ok, X509_STORE_CTX *ctx));
+
+=head1 DESCRIPTION
+
+X509_STORE_CTX_set_verify_cb() sets the verification callback of B<ctx> to
+B<verify_cb> overwriting any existing callback.
+
+The verification callback can be used to customise the operation of certificate
+verification, either by overriding error conditions or logging errors for
+debugging purposes.
+
+However a verification callback is B<not> essential and the default operation
+is often sufficient.
+
+The B<ok> parameter to the callback indicates the value the callback should
+return to retain the default behaviour. If it is zero then and error condition
+is indicated. If it is 1 then no error occurred. If the flag
+B<X509_V_FLAG_NOTIFY_POLICY> is set then B<ok> is set to 2 to indicate the
+policy checking is complete.
+
+The B<ctx> parameter to the callback is the B<X509_STORE_CTX> structure that
+is performing the verification operation. A callback can examine this
+structure and receive additional information about the error, for example
+by calling X509_STORE_CTX_get_current_cert(). Additional application data can
+be passed to the callback via the B<ex_data> mechanism.
+
+=head1 WARNING
+
+In general a verification callback should B<NOT> unconditionally return 1 in
+all circumstances because this will allow verification to succeed no matter
+what the error. This effectively removes all security from the application
+because B<any> certificate (including untrusted generated ones) will be
+accepted.
+
+=head1 NOTES
+
+The verification callback can be set and inherited from the parent structure
+performing the operation. In some cases (such as S/MIME verification) the
+B<X509_STORE_CTX> structure is created and destroyed internally and the
+only way to set a custom verification callback is by inheriting it from the
+associated B<X509_STORE>.
+
+=head1 RETURN VALUES
+
+X509_STORE_CTX_set_verify_cb() does not return a value.
+
+=head1 EXAMPLES
+
+Default callback operation:
+
+ int verify_callback(int ok, X509_STORE_CTX *ctx)
+        {
+        return ok;
+        }
+
+Simple example, suppose a certificate in the chain is expired and we wish
+to continue after this error:
+
+ int verify_callback(int ok, X509_STORE_CTX *ctx)
+        {
+        /* Tolerate certificate expiration */
+        if (X509_STORE_CTX_get_error(ctx) == X509_V_ERR_CERT_HAS_EXPIRED)
+                        return 1;
+        /* Otherwise don't override */
+        return ok;
+        }
+
+More complex example, we don't wish to continue after B<any> certificate has
+expired just one specific case:
+
+ int verify_callback(int ok, X509_STORE_CTX *ctx)
+        {
+        int err = X509_STORE_CTX_get_error(ctx);
+        X509 *err_cert = X509_STORE_CTX_get_current_cert(ctx);
+        if (err == X509_V_ERR_CERT_HAS_EXPIRED)
+                {
+                if (check_is_acceptable_expired_cert(err_cert)
+                        return 1;
+                }
+        return ok;
+        }
+
+Full featured logging callback. In this case the B<bio_err> is assumed to be
+a global logging B<BIO>, an alternative would to store a BIO in B<ctx> using
+B<ex_data>.
+        
+ int verify_callback(int ok, X509_STORE_CTX *ctx)
+        {
+        X509 *err_cert;
+        int err,depth;
+
+        err_cert = X509_STORE_CTX_get_current_cert(ctx);
+        err =   X509_STORE_CTX_get_error(ctx);
+        depth = X509_STORE_CTX_get_error_depth(ctx);

+=head1 DESCRIPTION
+
+These functions manipulate the B<X509_VERIFY_PARAM> structure associated with
+a certificate verification operation. 
+
+The X509_VERIFY_PARAM_set_flags() function sets the flags in B<param> by oring
+it with B<flags>. See the B<VERIFICATION FLAGS> section for a complete
+description of values the B<flags> parameter can take.
+
+X509_VERIFY_PARAM_get_flags() returns the flags in B<param>.
+
+X509_VERIFY_PARAM_clear_flags() clears the flags B<flags> in B<param>.
+
+X509_VERIFY_PARAM_set_purpose() sets the verification purpose in B<param>
+to B<purpose>. This determines the acceptable purpose of the certificate
+chain, for example SSL client or SSL server.
+
+X509_VERIFY_PARAM_set_trust() sets the trust setting in B<param> to 
+B<trust>.
+
+X509_VERIFY_PARAM_set_time() sets the verification time in B<param> to
+B<t>. Normally the current time is used.
+
+X509_VERIFY_PARAM_add0_policy() enables policy checking (it is disabled
+by default) and adds B<policy> to the acceptable policy set.
+
+X509_VERIFY_PARAM_set1_policies() enables policy checking (it is disabled
+by default) and sets the acceptable policy set to B<policies>. Any existing
+policy set is cleared. The B<policies> parameter can be B<NULL> to clear
+an existing policy set.
+
+X509_VERIFY_PARAM_set_depth() sets the maximum verification depth to B<depth>.
+That is the maximum number of untrusted CA certificates that can appear in a
+chain.
+
+=head1 RETURN VALUES
+
+X509_VERIFY_PARAM_set_flags(), X509_VERIFY_PARAM_clear_flags(), 
+X509_VERIFY_PARAM_set_purpose(), X509_VERIFY_PARAM_set_trust(),
+X509_VERIFY_PARAM_add0_policy() and X509_VERIFY_PARAM_set1_policies() return 1
+for success and 0 for failure. 
+
+X509_VERIFY_PARAM_get_flags() returns the current verification flags.
+
+X509_VERIFY_PARAM_set_time() and X509_VERIFY_PARAM_set_depth() do not return
+values.
+
+X509_VERIFY_PARAM_get_depth() returns the current verification depth.
+
+=head1 VERIFICATION FLAGS
+
+The verification flags consists of zero or more of the following flags
+ored together.
+
+B<X509_V_FLAG_CRL_CHECK> enables CRL checking for the certificate chain leaf
+certificate. An error occurs if a suitable CRL cannot be found. 
+
+B<X509_V_FLAG_CRL_CHECK_ALL> enables CRL checking for the entire certificate
+chain.
+
+B<X509_V_FLAG_IGNORE_CRITICAL> disabled critical extension checking. By default
+any unhandled critical extensions in certificates or (if checked) CRLs results
+in a fatal error. If this flag is set unhandled critical extensions are
+ignored. B<WARNING> setting this option for anything other than debugging
+purposes can be a security risk. Finer control over which extensions are
+supported can be performed in the verification callback.
+
+THe B<X509_V_FLAG_X509_STRICT> flag disables workarounds for some broken
+certificates and makes the verification strictly apply B<X509> rules.
+
+B<X509_V_FLAG_ALLOW_PROXY_CERTS> enables proxy certificate verification.
+
+B<X509_V_FLAG_POLICY_CHECK> enables certificate policy checking, by default
+no policy checking is peformed. Additional information is sent to the 
+verification callback relating to policy checking.
+
+B<X509_V_FLAG_EXPLICIT_POLICY>, B<X509_V_FLAG_INHIBIT_ANY> and
+B<X509_V_FLAG_INHIBIT_MAP> set the B<require explicit policy>, B<inhibit any
+policy> and B<inhibit policy mapping> flags respectively as defined in
+B<RFC3280>. Policy checking is automatically enabled if any of these flags
+are set.
+
+If B<X509_V_FLAG_NOTIFY_POLICY> is set and the policy checking is successful
+a special status code is set to the verification callback. This permits it
+to examine the valid policy tree and perform additional checks or simply
+log it for debugging purposes.
+
+By default some addtional features such as indirect CRLs and CRLs signed by
+different keys are disabled. If B<X509_V_FLAG_EXTENDED_CRL_SUPPORT> is set
+they are enabled.
+
+If B<X509_V_FLAG_USE_DELTAS> ise set delta CRLs (if present) are used to
+determine certificate status. If not set deltas are ignored.
+
+B<X509_V_FLAG_CHECK_SS_SIGNATURE> enables checking of the root CA self signed
+cerificate signature. By default this check is disabled because it doesn't
+add any additional security but in some cases applications might want to
+check the signature anyway. A side effect of not checking the root CA
+signature is that disabled or unsupported message digests on the root CA
+are not treated as fatal errors.
+
+The B<X509_V_FLAG_CB_ISSUER_CHECK> flag enables debugging of certificate
+issuer checks. It is B<not> needed unless you are logging certificate
+verification. If this flag is set then additional status codes will be sent
+to the verification callback and it B<must> be prepared to handle such cases
+without assuming they are hard errors.
+
+=head1 NOTES
+
+The above functions should be used to manipulate verification parameters
+instead of legacy functions which work in specific structures such as
+X509_STORE_CTX_set_flags().
+
+=head1 BUGS
+
+Delta CRL checking is currently primitive. Only a single delta can be used and
+(partly due to limitations of B<X509_STORE>) constructed CRLs are not 
+maintained.
+
+If CRLs checking is enable CRLs are expected to be available in the
+corresponding B<X509_STORE> structure. No attempt is made to download
+CRLs from the CRL distribution points extension.
+
+=head1 EXAMPLE
+
+Enable CRL checking when performing certificate verification during SSL 
+connections associated with an B<SSL_CTX> structure B<ctx>:
+
+  X509_VERIFY_PARAM *param;
+  param = X509_VERIFY_PARAM_new();
+  X509_VERIFY_PARAM_set_flags(param, X509_V_FLAG_CRL_CHECK);
+  SSL_CTX_set1_param(ctx, param);
+  X509_VERIFY_PARAM_free(param);

+=head1 NAME
+
+X509_verify_cert - discover and verify X509 certificte chain
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509.h>
+
+ int X509_verify_cert(X509_STORE_CTX *ctx);
+
+=head1 DESCRIPTION
+
+The X509_verify_cert() function attempts to discover and validate a
+certificate chain based on parameters in B<ctx>. A complete description of
+the process is contained in the L<verify(1)|verify(1)> manual page.
+
+=head1 RETURN VALUES
+
+If a complete chain can be built and validated this function returns 1,
+otherwise it return zero, in exceptional circumstances it can also
+return a negative code.
+
+If the function fails additional error information can be obtained by
+examining B<ctx> using, for example X509_STORE_CTX_get_error().
+
+=head1 NOTES
+
+Applications rarely call this function directly but it is used by
+OpenSSL internally for certificate validation, in both the S/MIME and
+SSL/TLS code.
+
+The negative return value from X509_verify_cert() can only occur if no
+certificate is set in B<ctx> (due to a programming error) or if a retry
+operation is requested during internal lookups (which never happens with
+standard lookup methods). It is however recommended that application check
+for <= 0 return value on error.
+
+=head1 BUGS
+
+This function uses the header B<x509.h> as opposed to most chain verification
+functiosn which use B<x509_vfy.h>.
