The vernam cipher, sometimes known as the 'one time pad', is a stream cipher, which providing certain requirements are met, can be theoretically unbreakable.
RC4 (Rivest Cipher 4). RC4 is one of the most used software-based stream ciphers in the world. The cipher is included in popular Internet protocols such as SSL (Secure Sockets Layer) and WEP (for wireless network security).C4 (Rivest Cipher 4).
