WebRC4 is a stream symmetric cipher. It operates by creating long keystream sequences and adding them to data bytes. RC4 encrypts data by adding it XOR byte by byte, one after the other, to keystream bytes. The whole RC4 algorithm is based on creating keystream bytes. The keystream is received from a 1-d table called the T table.
