Rivest Cipher 4 (RC4): A stream cipher that was widely used in various protocols, most notably in WEP for wireless network security and in early versions of SSL/TLS for securing web traffic. However, due to vulnerabilities that have been discovered over time, RC4 is no longer considered secure and has been largely replaced by more robust encryption methods.
