Inverse RC4
Apr. 3rd, 2009 02:44 pmGiven the keystream output from RC4 (ARC4), is there an inverse RC4 function which would give me either the key schedule or even the original key.
I have the plaintext, the cyphertext, the key stream, and the nonce which is mixed with an unknown key. I'm trying to recover that unknown key part.
Assume that the first N-bytes of the keystream were not discarded.
