There are two parts here: A part that handles the expansion of the key. A part that handles the encryption of the data. The Data Encryption Standard encryption algorithm on which Triple DES is based was first published in 1975. Over the years, as computers grew faster, the block cipher with a simple 56-bit key ... This plugin is a dynamically loadable wrapper of the Blowfish block cipher C API as im- plemented by libssl (OpenSSL). The cipher operates on 64 bit (8 byte) blocks of data and uses a variable size key. Keys with 128 bits (16 bytes) are considered good for modest encryption. Blowfish can be used in the same modes as DES, is quite a bit faster than DES, and much faster than IDEA or RC2.
