Rc4 stream cipher algorithm
WebRC4 Algorithm. In the RC4 encryption algorithm, the key stream is completely independent of the plaintext used. An 8 * 8 S-Box (S0 S255), where each of the entries is a permutation of the numbers 0 to 255, and the permutation is a function of the variable length key. There are two counters i, and j, both initialized to 0 used in the algorithm.
