RC4’s internal state is an array of 256 bytes, denoted as S[], ranging from 0-255. RC4 will use its Key Scheduling Algorithm (KSA) to randomly swap the bytes in S[] using the user inputted key as the seed. S[] is then used to generate a keystream via the Pseudo-Random Generation Algorithm (PRGA). slr7 compatibility cartridge
