Stream.arcfour
The ARCfour (``alleged RC4'') stream cipher. The argument is the key, and must be of length 1 to 256. This stream cipher works by xor-ing the input with the output of a key-dependent pseudo random number generator. Thus, decryption is the same function as encryption.

encrypts or decrypts len
characters, read from byte array src
starting at position spos
