The age one becomes a legal adult in the US is largely the age at which most children are considered adults in the world. A few countries set this age lower, but in most of the Western world, one is considered an adult at 18.
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).

Keystream Dictionaries. The security of RC4, which is the underlying encryption method in WEP, depends in part on not repeating the same keystream. WEP does this by using the initialization vector (IV) to permit 224 (about 16 million) possible keystreams for each key.
