WebDec 20, 2024 · The cryptographic algorithm, known as ARC4 ( A lleged RC4 ), is a stream cipher that is widely used in various information security systems on computer networks (for example, SSL and TLS protocols, WEP and WPA wireless security algorithms). The original RC4 stream cipher was created by Ronald Rivest of RSA Security. WebDec 15, 2011 · RC4 was invented in 1987 by Ron Rivest. It spent its first seven years as an RSA trade secret before it was eventually leaked to a public mailing list in 1994. The rest, as they say, is history. You could argue that RC4’s rise was inevitable. By the time of its leak, it was already in widespread commercial use.
