RC4 Stream Cipher

RC4 is a stream cipher that was designed by Ron Rivest in 1987. This cipher is well-known for its simplicity and speed in software. RC4 is used in many protocols like WEP, WPA, Microsoft Point-to-Point encryption, etc. It was once used in protocols like TLS also. But, multiple vulnerabilities are discovered in RC4 which makes it insecure.

How does the RC4 algorithm work? In this article, we will discuss that in detail.
