RC4 Byte Biases

RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR meaning Alleged RC4) is a stream cipher. The cipher at one time was very popular and was found used in many technologies. However, several weaknesses have been discovered over time in RC4, which has meant a lack of use in recent years. One of the weaknesses is that RC4 produces keystreams that can be biased to different extents, which makes them vulnerable to distinguishing attacks
