Detailed Description

ChaCha12 stream cipher.

Bernstein and ECRYPT's ChaCha 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.
