What is RC4 ? (by Mukul Sabharwal)
RC4 is fairly fast, secure and symmetric encryption algorithm. Devloped by Ron Rivest in 1987 was kept trade secret until 9th September 1994 when it was posted on a Cypherpunks mailing list. Generally the key it uses is limited to 40 bits for various legal reasons but 128bits is the more common forms these days.
