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.

Standard 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the RC4 key. At the time that the original WEP standard was drafted, the U.S. Government's export restrictions on cryptographic technology limited the key size.
