Module stream

Stream cipher implementations

This module provides implementations of stream ciphers, which are symmetric key ciphers that encrypt plaintext digits one at a time with a pseudorandom keystream.

Available Stream Ciphers

• ChaCha20: A high-speed stream cipher designed by Daniel J. Bernstein

Security Considerations

Stream ciphers require unique nonces for each encryption operation with the same key. Reusing a nonce with the same key completely breaks the security of the cipher.
