The C-code for the RC4 is given below: (Note that we are using modulo function as "mod" in the code below for clarity. Embed Embed this gist in your website. The state table is used for subsequent generation of pseudo-random bytes and then to generate a pseudo-random stream which is XOR-ed with the plaintext to give the cipher text. Since RC4 generates a pseudorandom stream of bits, it can be used for encryption by combining it with the plaintext using bit-wise exclusive-or; decryption is perform the same way.
