Excuse me for being blunt... But two things are annoying the kajeebees
out of me.
1. Call it RC4 already. I think it's safe to say the secret is out.
ARCFOUR is RC4.
2. Why not use a cipher like AES in CTR mode if you need a stream
cipher? It's simpler, off-the-shelf and doesn't require "hardening"
[well maybe timing resistence depending on your threat model].
Yet another program that uses RC4 isn't what the world needs. As an
educational tool it's marginal as you're basically learning how to do
cryptography ineffectively.
