RC4 encryption

The RC4 (Rivest Cipher 4) is a stream cipher invented by Ron Rivest in 1987. It is known for high speed and simplicity in software implementations. However, multiple vulnerabilities have been discovered in RC4, rendering it insecure. Therefore, Microsoft and Mozilla have issued recommendations to prohibit the use of RC4 in TLS (used for SSL and WEP).
