-=head1 DESCRIPTION
-
-This library implements the Blowfish cipher, which was invented and described
-by Counterpane (see http://www.counterpane.com/blowfish.html ).
-
-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 L<des_modes(7)|des_modes(7)>).  Blowfish is currently one
-of the faster block ciphers.  It is quite a bit faster than DES, and much
-faster than IDEA or RC2.
-
-Blowfish consists of a key setup phase and the actual encryption or decryption
-phase.
-
-BF_set_key() sets up the B<BF_KEY> B<key> using the B<len> bytes long key
-at B<data>.
-
-BF_ecb_encrypt() is the basic Blowfish encryption and decryption function.
-It encrypts or decrypts the first 64 bits of B<in> using the key B<key>,
-putting the result in B<out>.  B<enc> decides if encryption (B<BF_ENCRYPT>)
-or decryption (B<BF_DECRYPT>) shall be performed.  The vector pointed at by
-B<in> and B<out> must be 64 bits in length, no less.  If they are larger,
-everything after the first 64 bits is ignored.
-
-The mode functions BF_cbc_encrypt(), BF_cfb64_encrypt() and BF_ofb64_encrypt()
-all operate on variable length data.  They all take an initialization vector
-B<ivec> which needs to be passed along into the next call of the same function 
-for the same message.  B<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
-B<ivec> is simply initialized to zero.
-BF_cbc_encrypt() operates on data that is a multiple of 8 bytes long, while
-BF_cfb64_encrypt() and 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 B<num>, which is a pointer to an integer where the current
-offset in B<ivec> is stored between calls.  This integer must be initialized
-to zero when B<ivec> is initialized.
-
-BF_cbc_encrypt() is the Cipher Block Chaining function for Blowfish.  It
-encrypts or decrypts the 64 bits chunks of B<in> using the key B<schedule>,
-putting the result in B<out>.  B<enc> decides if encryption (BF_ENCRYPT) or
-decryption (BF_DECRYPT) shall be performed.  B<ivec> must point at an 8 byte
-long initialization vector.
-
-BF_cfb64_encrypt() is the CFB mode for Blowfish with 64 bit feedback.
-It encrypts or decrypts the bytes in B<in> using the key B<schedule>,
-putting the result in B<out>.  B<enc> decides if encryption (B<BF_ENCRYPT>)
-or decryption (B<BF_DECRYPT>) shall be performed.  B<ivec> must point at an
-8 byte long initialization vector. B<num> must point at an integer which must
-be initially zero.
-
-BF_ofb64_encrypt() is the OFB mode for Blowfish with 64 bit feedback.
-It uses the same parameters as BF_cfb64_encrypt(), which must be initialized
-the same way.
-
-BF_encrypt() and BF_decrypt() are the lowest level functions for Blowfish
-encryption.  They encrypt/decrypt the first 64 bits of the vector pointed by
-B<data>, using the key B<key>.  These functions should not be used unless you
-implement 'modes' of Blowfish.  The alternative is to use 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.

-=head1 RETURN VALUES
-
-None of the functions presented here return any value.
-
-=head1 NOTE
-
-Applications should use the higher level functions
-L<EVP_EncryptInit(3)|EVP_EncryptInit(3)> etc. instead of calling the
-blowfish functions directly.

-=head1 HISTORY
-
-The Blowfish functions are available in all versions of SSLeay and OpenSSL.
