Detailed Description

Classes for ChaCha8, ChaCha12 and ChaCha20 stream ciphers.

Crypto++ provides Bernstein and ECRYPT's ChaCha from ChaCha, a variant of Salsa20 (2008.01.28). Bernstein's implementation is slightly different from the TLS working group's implementation for cipher suites TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256, and TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256.

Since: Crypto++ 5.6.4
