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 was created by Ron Rivest of RSA Security in 1987. While its official name is Rivest Cipher 4, the RC acronym is also known to stand for Ron's Code (see also RC2, RC5 and RC6). RC4 was first created as a trade secret, but in September 1994 a description of it was posted to the Cypherpunks mailing list.n cryptography, RC4 (also known as ARC4 or ARCFOUR meaning Alleged RC4, see below) is one of the most common software stream ciphers.
