A Cipher is an instance of Blowfish encryption using a particular key.

A KeySizeError is an Exception which indicates that the length of a given cipher key does not conform to the bounds key -> 1 < key < 56

Decrypt!(c::Cipher, dst::Array{UInt8, 1}, src::Array{UInt8, 1})

Decrypt decrypts the 8-byte buffer src using the key k and stores the result in dst.

Encrypt!(c::Cipher, dst::Array{UInt8, 1}, src::Array{UInt8, 1})

Encrypt encrypts the 8-byte buffer src using the key k and stores the result in dst. Note that for amounts of data larger than a block, it is not safe to just call Encrypt on successive blocks.

NewCipher(key::Array{UInt8, 1})

Generates a new instance of a blowfish cipher from a given cipher key

NewSaltedCipher(key::Array{UInt8, 1})

Generates a Cipher that folds a salt into its key schedule. For most purposes, NewCipher, instead of NewSaltedCipher, is sufficient and desirable. For bcrypt compatibility, the key can be over 56 bytes.
