Add Output Feedback Block (OFB) to the given block cipher. The integer argument n is the number of bytes processed at a time; it must lie between 1 and the block size of the underlying cipher, included. The returned block cipher has block size n. It is usable both for encryption and decryption.

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.
