Symmetric encryption is considered … WebRC4 generates a pseudo-random stream of bits (a key-stream). As with any stream cipher, these can be used for encryption by combining it with the plaintext using bit-wise exclusive-or. Decryption is performed the same way (since exclusive-or is a symmetric operation). To generate the key stream, the cipher makes use of a secret internal state ... bison infused
