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). Crypto++ also provides the IETF implementation of ChaCha using the ChaChaTLS name. 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. Finally, the library provides XChaCha: eXtended-nonce ChaCha and AEAD_XChaCha20_Poly1305 (rev. 03).

Since
ChaCha since Crypto++ 5.6.4, ChaChaTLS and XChaCha20 since Crypto++ 8.1
