RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. It was soon …

The name is based on the fact that in a room with 23 people or more, the odds are greater than 50% that two will share the same birthday. Many find this counterintuitive, and the birthday paradox illustrates why many people's instinct in probability (and risk) is wrong.
