I'm implementing the RC4 algorithm, which requires a state array with 
256 elements containing the bytes from 0 to 255. As the algorithm 
progresses, the elements of the array get shuffled around. This is what 
drives the pseudo-random number generator. But the size of the state 
array is always 256.

Cheers,
Daniel.
