It became prominent in the late nineties but has since fallen out of favor due to the rise of more secure algorithms, such as AES-256 and XChaCha20. Although it will be deprecated in 2024, it’s still implemented in some situations. 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 ... bjnh investments inc
