+.Sh DESCRIPTION
+This library implements the Blowfish cipher,
+which was invented and described by
+.An Counterpane .
+.Pp
+Blowfish is a block cipher that operates on 64 bit (8 byte) blocks of data.
+It uses a variable size key, but typically, 128 bit (16 byte) keys
+are considered good for strong encryption.
+Blowfish can be used in the same modes as DES (see
+.Xr des_modes 3 ) .
+Blowfish is currently one of the faster block ciphers.
+It is quite a bit faster than DES, and much faster than IDEA or RC2.
+.Pp
+Blowfish consists of a key setup phase
+and the actual encryption or decryption phase.
+.Pp
+.Fn BF_set_key
+sets up the
+.Vt BF_KEY
+.Fa key
+using the
+.Fa len
+bytes long key at
+.Fa data .
+.Pp
+.Fn BF_ecb_encrypt
+is the basic Blowfish encryption and decryption function.
+It encrypts or decrypts the first 64 bits of
+.Fa in
+using the key
+.Fa key ,
+putting the result in
+.Fa out .
+.Fa enc
+decides if encryption
+.Pq Dv BF_ENCRYPT
+or decryption
+.Pq Dv BF_DECRYPT
+shall be performed.
+The vector pointed at by
+.Fa in
+and
+.Fa out
+must be 64 bits in length, no less.
+If they are larger, everything after the first 64 bits is ignored.
+.Pp
+The mode functions
+.Fn BF_cbc_encrypt ,
+.Fn BF_cfb64_encrypt ,
+and
+.Fn BF_ofb64_encrypt
+all operate on variable length data.
+They all take an initialization vector
+.Fa ivec
+which needs to be passed along into the next call of the same function
+for the same message.
+.Fa ivec
+may be initialized with anything, but the recipient needs to know what
+it was initialized with, or it won't be able to decrypt.
+Some programs and protocols simplify this, like SSH, where
+.Fa ivec
+is simply initialized to zero.
+.Fn BF_cbc_encrypt
+operates on data that is a multiple of 8 bytes long, while
+.Fn BF_cfb64_encrypt
+and
+.Fn BF_ofb64_encrypt
+are used to encrypt an variable number of bytes (the amount
+does not have to be an exact multiple of 8).
+The purpose of the latter two is to simulate stream ciphers,
+and therefore, they need the parameter
+.Fa num ,
+which is a pointer to an integer where the current offset in
+.Fa ivec
+is stored between calls.
+This integer must be initialized to zero when
+.Fa ivec
+is initialized.
+.Pp
+.Fn BF_cbc_encrypt
+is the Cipher Block Chaining function for Blowfish.
+It encrypts or decrypts the 64 bits chunks of
+.Fa in
+using the key
+.Fa schedule ,
+putting the result in
+.Fa out .
+.Fa enc
+decides if encryption
+.Pq Dv BF_ENCRYPT
+or decryption
+.Pq Dv BF_DECRYPT
+shall be performed.
+.Fa ivec
+must point at an 8 byte long initialization vector.
+.Pp
+.Fn BF_cfb64_encrypt
+is the CFB mode for Blowfish with 64 bit feedback.
+It encrypts or decrypts the bytes in
+.Fa in
+using the key
+.Fa schedule ,
+putting the result in
+.Fa out .
+.Fa enc
+decides if encryption
+.Pq Dv BF_ENCRYPT
+or decryption
+.Pq Dv BF_DECRYPT
+shall be performed.
+.Fa ivec
+must point at an
+8 byte long initialization vector.
+.Fa num
+must point at an integer which must be initially zero.
+.Pp
+.Fn BF_ofb64_encrypt
+is the OFB mode for Blowfish with 64 bit feedback.
+It uses the same parameters as
+.Fn BF_cfb64_encrypt ,
+which must be initialized the same way.
+.Pp
+.Fn BF_encrypt
+and
+.Fn BF_decrypt
+are the lowest level functions for Blowfish encryption.
+They encrypt/decrypt the first 64 bits of the vector pointed by
+.Fa data ,
+using the key
+.Fa key .
+These functions should not be used unless you implement 'modes' of Blowfish.
+The alternative is to use
+.Fn BF_ecb_encrypt .
+If you still want to use these functions, you should be aware
+that they take each 32-bit chunk in host-byte order,
+which is little-endian on little-endian platforms
+and big-endian on big-endian ones.
+.Sh RETURN VALUES
+None of the functions presented here return any value.
+.Sh NOTE
+Applications should use the higher level functions
+.Xr EVP_EncryptInit 3
+etc. instead of calling the blowfish functions directly.
+.Sh HISTORY
+The Blowfish functions are available in all versions of SSLeay and OpenSSL.

+.Nm BIO
+.Nd I/O abstraction
+.Sh SYNOPSIS
+.In openssl/bio.h
+.Sh DESCRIPTION
+A BIO is an I/O abstraction,
+it hides many of the underlying I/O details from an application.
+If an application uses a BIO for its I/O, it can transparently handle
+SSL connections, unencrypted network connections and file I/O.
+.Pp
+There are two types of BIO, a source/sink BIO and a filter BIO.
+.Pp
+As its name implies, a source/sink BIO is a source and/or sink of data,
+examples include a socket BIO and a file BIO.
+.Pp
+A filter BIO takes data from one BIO and passes it through
+to another, or to the application.
+The data may be left unmodified (for example a message digest BIO)
+or translated (for example an encryption BIO).
+The effect of a filter BIO may change according to the I/O operation
+it is performing: for example an encryption BIO will encrypt data
+if it is being written to and decrypt data if it is being read from.
+.Pp
+BIOs can be joined together to form a chain
+(a single BIO is a chain with one component).
+A chain normally consist of one source/sink BIO
+and one or more filter BIOs.
+Data read from or written to the first BIO then traverses the chain
+to the end (normally a source/sink BIO).

+.Sh DESCRIPTION
+.Fn BIO_ctrl ,
+.Fn BIO_callback_ctrl ,
+.Fn BIO_ptr_ctrl ,
+and
+.Fn BIO_int_ctrl
+are BIO "control" operations taking arguments of various types.
+These functions are not normally called directly,
+various macros are used instead.
+The standard macros are described below, macros specific to a
+particular type of BIO are described in the specific BIO's manual
+page as well as any special features of the standard calls.
+.Pp
+.Fn BIO_reset
+typically resets a BIO to some initial state, in the case
+of file related BIOs for example it rewinds the file pointer
+to the start of the file.
+.Pp
+.Fn BIO_seek
+resets a file related BIO's (that is file descriptor and
+FILE BIOs) file position pointer to
+.Fa ofs
+bytes from start of file.
+.Pp
+.Fn BIO_tell
+returns the current file position of a file related BIO.
+.Pp
+.Fn BIO_flush
+normally writes out any internally buffered data, in some cases
+it is used to signal EOF and that no more data will be written.
+.Pp
+.Fn BIO_eof
+returns 1 if the BIO has read EOF, the precise meaning of
+"EOF" varies according to the BIO type.
+.Pp
+.Fn BIO_set_close
+sets the BIO
+.Fa b
+close flag to
+.Fa flag .
+.Fa flag
+can take the value
+.Dv BIO_CLOSE
+or
+.Dv BIO_NOCLOSE .
+Typically
+.Dv BIO_CLOSE
+is used in a source/sink BIO to indicate that the underlying I/O stream
+should be closed when the BIO is freed.
+.Pp
+.Fn BIO_get_close
+returns the BIO's close flag.
+.Pp
+.Fn BIO_pending ,
+.Fn BIO_ctrl_pending ,
+.Fn BIO_wpending ,
+and
+.Fn BIO_ctrl_wpending
+return the number of pending characters in the BIO's read and write buffers.
+Not all BIOs support these calls.
+.Fn BIO_ctrl_pending
+and
+.Fn BIO_ctrl_wpending
+return a
+.Vt size_t
+type and are functions,
+.Fn BIO_pending
+and
+.Fn BIO_wpending
+are macros which call
+.Fn BIO_ctrl .
+.Sh RETURN VALUES
+.Fn BIO_reset
+normally returns 1 for success and 0 or -1 for failure.
+File BIOs are an exception, they return 0 for success and -1 for failure.
+.Pp
+.Fn BIO_seek
+and
+.Fn BIO_tell
+both return the current file position on success
+and -1 for failure, except file BIOs which for
+.Fn BIO_seek
+always return 0 for success and -1 for failure.
+.Pp
+.Fn BIO_flush
+returns 1 for success and 0 or -1 for failure.
+.Pp
+.Fn BIO_eof
+returns 1 if EOF has been reached 0 otherwise.
+.Pp
+.Fn BIO_set_close
+always returns 1.
+.Pp
+.Fn BIO_get_close
+returns the close flag value
+.Dv BIO_CLOSE
+or
+.Dv BIO_NOCLOSE .
+.Pp
+.Fn BIO_pending ,
+.Fn BIO_ctrl_pending ,
+.Fn BIO_wpending ,
+and
+.Fn BIO_ctrl_wpending
+return the amount of pending data.
+.Sh NOTES
+Because it can write data,
+.Fn BIO_flush
+may return 0 or -1 indicating that the call should be retried later
+in a similar manner to
+.Fn BIO_write .
+The
+.Fn BIO_should_retry
+call should be used and appropriate action taken is the call fails.
+.Pp
+The return values of
+.Fn BIO_pending
+and
+.Fn BIO_wpending
+may not reliably determine the amount of pending data in all cases.
+For example in the case of a file BIO some data may be available in the
+.Vt FILE
+structure's internal buffers but it is not possible
+to determine this in a portably way.
+For other types of BIO they may not be supported.
+.Pp
+If they do not internally handle a particular
+.Fn BIO_ctrl
+operation, filter BIOs usually pass the operation
+to the next BIO in the chain.
+This often means there is no need to locate the required BIO for
+a particular operation, it can be called on a chain and it will
+be automatically passed to the relevant BIO.
+However this can cause unexpected results:
+for example no current filter BIOs implement
+.Fn BIO_seek ,
+but this may still succeed if the chain ends
+in a FILE or file descriptor BIO.
+.Pp
+Source/sink BIOs return an 0 if they do not recognize the
+.Fn BIO_ctrl
+operation.
+.Sh BUGS
+Some of the return values are ambiguous and care should be taken.
+In particular a return value of 0 can be returned if an operation
+is not supported, if an error occurred, if EOF has not been reached
+and in the case of
+.Fn BIO_seek
+on a file BIO for a successful operation.

+The flag
+.Dv BIO_FLAGS_BASE64_NO_NL
+can be set with
+.Xr BIO_set_flags 3
+to encode the data all on one line
+or expect the data to be all on one line.
+.Sh NOTES
+Because of the format of base64 encoding the end of the encoded

+.Sh RETURN VALUES
+.Fn BIO_f_base64
+returns the base64 BIO method.
+.Sh EXAMPLES

+        BIO_write(bio_out, inbuf, inlen);
+
+BIO_flush(bio_out);
+BIO_free_all(b64);
+.Ed
+.Sh BUGS
+The ambiguity of EOF in base64 encoded data can cause additional
+data following the base64 encoded block to be misinterpreted.
+.Pp
+There should be some way of specifying a test that the BIO can perform
+to reliably determine EOF (for example a MIME boundary).

+.Sh DESCRIPTION
+.Fn BIO_f_buffer
+returns the buffering BIO method.
+.Pp
+Data written to a buffering BIO is buffered and periodically written
+to the next BIO in the chain.
+Data read from a buffering BIO comes from an internal buffer
+which is filled from the next BIO in the chain.
+Both
+.Xr BIO_gets 3
+and
+.Xr BIO_puts 3
+are supported.
+.Pp
+Calling
+.Xr BIO_reset 3
+on a buffering BIO clears any buffered data.
+.Pp
+.Fn BIO_get_buffer_num_lines
+returns the number of lines currently buffered.
+.Pp
+.Fn BIO_set_read_buffer_size ,
+.Fn BIO_set_write_buffer_size ,
+and
+.Fn BIO_set_buffer_size
+set the read, write or both read and write buffer sizes to
+.Fa size .
+The initial buffer size is
+.Dv DEFAULT_BUFFER_SIZE ,
+currently 4096.
+Any attempt to reduce the buffer size below
+.Dv DEFAULT_BUFFER_SIZE
+is ignored.
+Any buffered data is cleared when the buffer is resized.
+.Pp
+.Fn BIO_set_buffer_read_data
+clears the read buffer and fills it with
+.Fa num
+bytes of
+.Fa buf .
+If
+.Fa num
+is larger than the current buffer size the buffer is expanded.
+.Sh NOTES
+Buffering BIOs implement
+.Xr BIO_gets 3
+by using
+.Xr BIO_read 3
+operations on the next BIO in the chain.
+By prepending a buffering BIO to a chain
+it is therefore possible to provide
+.Xr BIO_gets 3
+functionality if the following BIOs do not support it (for example SSL BIOs).
+.Pp
+Data is only written to the next BIO in the chain
+when the write buffer fills or when
+.Xr BIO_flush 3
+is called.
+It is therefore important to call
+.Xr BIO_flush 3
+whenever any pending data should be written
+such as when removing a buffering BIO using
+.Xr BIO_pop 3 .
+.Xr BIO_flush 3
+may need to be retried if the ultimate source/sink BIO is non blocking.
+.Sh RETURN VALUES
+.Fn BIO_f_buffer

+.Pp
+.Fn BIO_set_read_buffer_size ,

+.Sh DESCRIPTION
+.Fn BIO_f_md
+returns the message digest BIO method.
+This is a filter BIO that digests any data passed through it.
+It is a BIO wrapper for the digest routines
+.Fn EVP_DigestInit ,
+.Fn EVP_DigestUpdate ,
+and
+.Fn EVP_DigestFinal .
+.Pp
+Any data written or read through a digest BIO using
+.Xr BIO_read 3
+and
+.Xr BIO_write 3
+is digested.
+.Pp
+.Xr BIO_gets 3 ,
+if its
+.Sy size
+parameter is large enough,
+finishes the digest calculation and returns the digest value.
+.Xr BIO_puts 3
+is
+not supported.
+.Pp
+.Xr BIO_reset 3
+reinitialises a digest BIO.
+.Pp
+.Fn BIO_set_md
+sets the message digest of BIO
+.Fa b
+to
+.Fa md :
+this must be called to initialize a digest BIO
+before any data is passed through it.
+It is a
+.Xr BIO_ctrl 3
+macro.
+.Pp
+.Fn BIO_get_md
+places the a pointer to the digest BIOs digest method in
+.Fa mdp .
+It is a
+.Xr BIO_ctrl 3
+macro.
+.Pp
+.Fn BIO_get_md_ctx
+returns the digest BIOs context in
+.Fa mdcp .
+.Sh NOTES
+The context returned by
+.Fn BIO_get_md_ctx
+can be used in calls to
+.Xr EVP_DigestFinal 3
+and also in the signature routines
+.Xr EVP_SignFinal 3
+and
+.Xr EVP_VerifyFinal 3 .
+.Pp
+The context returned by
+.Fn BIO_get_md_ctx
+is an internal context structure.
+Changes made to this context will affect the digest BIO itself, and
+the context pointer will become invalid when the digest BIO is freed.
+.Pp
+After the digest has been retrieved from a digest BIO,
+it must be reinitialized by calling
+.Xr BIO_reset 3
+or
+.Fn BIO_set_md
+before any more data is passed through it.
+.Pp
+If an application needs to call
+.Xr BIO_gets 3
+or
+.Xr BIO_puts 3
+through a chain containing digest BIOs,
+then this can be done by prepending a buffering BIO.
+.Pp
+Before OpenSSL 1.0.0 the call to
+.Fn BIO_get_md_ctx
+would only work if the BIO had been initialized for example by calling
+.Fn BIO_set_md .
+In OpenSSL 1.0.0 and later the context is always returned
+and the BIO is state is set to initialized.
+This allows applications to initialize the context externally
+if the standard calls such as
+.Fn BIO_set_md
+are not sufficiently flexible.
+.Sh RETURN VALUES
+.Fn BIO_f_md
+returns the digest BIO method.
+.Pp
+.Fn BIO_set_md ,
+.Fn BIO_get_md ,
+and
+.Fn BIO_get_md_ctx
+return 1 for success and 0 for failure.
+.Sh EXAMPLES
+The following example creates a BIO chain containing an SHA1 and MD5
+digest BIO and passes the string "Hello World" through it.
+Error checking has been omitted for clarity.
+.Bd -literal -offset 2n
+BIO *bio, *mdtmp;
+const char message[] = "Hello World";
+bio = BIO_new(BIO_s_null());
+mdtmp = BIO_new(BIO_f_md());
+BIO_set_md(mdtmp, EVP_sha1());
+/*
+ * For BIO_push() we want to append the sink BIO
+ * and keep a note of the start of the chain.
+ */
+bio = BIO_push(mdtmp, bio);
+mdtmp = BIO_new(BIO_f_md());
+BIO_set_md(mdtmp, EVP_md5());
+bio = BIO_push(mdtmp, bio);
+/* Note: mdtmp can now be discarded */
+BIO_write(bio, message, strlen(message));
+.Ed
+.Pp
+The next example digests data by reading through a chain instead:
+.Bd -literal -offset 2n
+BIO *bio, *mdtmp;
+char buf[1024];
+int rdlen;
+
+bio = BIO_new_file(file, "rb");
+mdtmp = BIO_new(BIO_f_md());
+BIO_set_md(mdtmp, EVP_sha1());
+bio = BIO_push(mdtmp, bio);
+mdtmp = BIO_new(BIO_f_md());
+BIO_set_md(mdtmp, EVP_md5());
+bio = BIO_push(mdtmp, bio);
+do {
+        rdlen = BIO_read(bio, buf, sizeof(buf));
+        /* Might want to do something with the data here */
+} while (rdlen > 0);
+.Ed
+.Pp
+This next example retrieves the message digests from a BIO chain
+and outputs them.
+This could be used with the examples above.
+.Bd -literal -offset 2n
+BIO *mdtmp;
+unsigned char mdbuf[EVP_MAX_MD_SIZE];
+int mdlen;
+int i;
+
+mdtmp = bio;    /* Assume bio has previously been set up */
+do {
+        EVP_MD *md;
+        mdtmp = BIO_find_type(mdtmp, BIO_TYPE_MD);
+        if (!mdtmp)
+                break;
+        BIO_get_md(mdtmp, &md);
+        printf("%s digest", OBJ_nid2sn(EVP_MD_type(md)));
+        mdlen = BIO_gets(mdtmp, mdbuf, EVP_MAX_MD_SIZE);
+        for(i = 0; i < mdlen; i++)
+                printf(":%02X", mdbuf[i]);
+        printf("\en");
+        mdtmp = BIO_next(mdtmp);
+} while(mdtmp);
+BIO_free_all(bio);
+.Ed
+.Sh BUGS
+The lack of support for
+.Xr BIO_puts 3
+and the non standard behaviour of
+.Xr BIO_gets 3
+could be regarded as anomalous.
+It could be argued that
+.Xr BIO_gets 3
+and
+.Xr BIO_puts 3
+should be passed to the next BIO in the chain and digest the data
+passed through and that digests should be retrieved using a separate
+.Xr BIO_ctrl 3
+call.

+The function
+.Fn BIO_find_type
+searches for a BIO of a given type in a chain, starting at BIO
+.Fa b .
+If
+.Fa bio_type
+is a specific type (such as
+.Dv BIO_TYPE_MEM ) ,
+then a search is made for a BIO of that type.
+If
+.Fa bio_type
+is a general type (such as
+.Dv BIO_TYPE_SOURCE_SINK ) ,
+then the next matching BIO of the given general type is searched for.
+.Fn BIO_find_type
+returns the next matching BIO or
+.Dv NULL
+if none is found.
+.Pp
+Note: not all the
+.Dv BIO_TYPE_*
+types above have corresponding BIO implementations.
+.Pp
+.Fn BIO_next
+returns the next BIO in a chain.
+It can be used to traverse all BIOs in a chain or used in conjunction with
+.Fn BIO_find_type
+to find all BIOs of a certain type.
+.Pp
+.Fn BIO_method_type
+returns the type of a BIO.
+.Sh RETURN VALUES
+.Fn BIO_find_type
+returns a matching BIO or
+.Dv NULL
+for no match.
+.Pp
+.Fn BIO_next
+returns the next BIO in a chain.
+.Pp
+.Fn BIO_method_type
+returns the type of the BIO
+.Fa b .
+.Sh NOTES
+.Fn BIO_next
+was added to OpenSSL 0.9.6 to provide a 'clean' way to traverse a BIO
+chain or find multiple matches using
+.Fn BIO_find_type .
+Previous versions had to use:
+.Pp
+.Dl next = bio->next_bio;
+.Sh BUGS
+.Fn BIO_find_type
+in OpenSSL 0.9.5a and earlier could not be safely passed a
+.Dv NULL
+pointer for the
+.Fa b
+argument.
+.Sh EXAMPLE
+Traverse a chain looking for digest BIOs:

+BIO *btmp;
+btmp = in_bio;  /* in_bio is chain to search through */
+
+do {
+        btmp = BIO_find_type(btmp, BIO_TYPE_MD);

+.Fn BIO_new_CMS

+.Sh RETURN VALUES

+.Sh NOTES
+The chain returned by this function behaves like a standard filter BIO.
+It supports non blocking I/O.
+Content is processed and streamed on the fly and not all held in memory
+at once: so it is possible to encode very large structures.
+After all content has been written through the chain
+.Xr BIO_flush 3
+must be called to finalise the structure.
+.Pp
+The
+.Dv CMS_STREAM
+flag must be included in the corresponding
+.Fa flags
+parameter of the
+.Fa cms
+creation function.
+.Pp
+If an application wishes to write additional data to
+.Fa out ,
+BIOs should be removed from the chain using
+.Xr BIO_pop 3
+and freed with
+.Xr BIO_free 3
+until
+.Fa out
+is reached.
+If no additional data needs to be written,
+.Xr BIO_free_all 3
+can be called to free up the whole chain.
+.Pp
+Any content written through the filter is used verbatim:
+no canonical translation is performed.
+.Pp
+It is possible to chain multiple BIOs to, for example,
+create a triple wrapped signed, enveloped, signed structure.
+In this case it is the application's responsibility
+to set the inner content type of any outer
+.Vt CMS_ContentInfo
+structures.
+.Pp
+Large numbers of small writes through the chain should be avoided as this
+will produce an output consisting of lots of OCTET STRING structures.
+Prepending a

+buffering BIO will prevent this.
+.Sh SEE ALSO
