RC4 Encryption AlgorithmRC4 encryption algorithm is the number one in the famous RSA trio Ron Rivest designed a variable-length stream encryption algorithm cluster in 1987. It is called a cluster, because its core part of the S-box length can be arbitrary, but generally 256 bytes. The speed of the algorithm can reach about 10 times times of DES encryption, and it has a high level of nonlinearity. RC4 was or
