+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.
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
