Class Block.blowfish_encrypt

The Blowfish block cipher, in encryption mode. The string argument is the key; its length must be between 4 and 56.

method blocksize : int

The size in bytes of the blocks manipulated by the cipher.

method transform : bytes -> int -> bytes -> int -> unit

transform src spos dst dpos encrypts or decrypts one block of data. The input data is read from byte array src at positions spos, ..., spos + blocksize - 1, and the output data is stored in byte array dst at positions dpos, ..., dpos + blocksize - 1.

method wipe : unit

Erase the internal state of the block cipher, such as all key-dependent material.
