ChaCha20-Poly1305 is an authenticated encryption with additional data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. Its usage in IETF protocols is standardized in RFC 8439. It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM. WebThe API of the cipher and its finite state machine are the same as for the modern modes of operation of block ciphers. You create a new cipher by calling Crypto.Cipher.ChaCha20_Poly1305.new ().

WebSSL 3.0 and TLS 1.0 are susceptible to known attacks on the protocol; they are disabled entirely. Disabling TLS 1.1 is (as of August 2016) mostly optional; TLS 1.2 provides stronger encryption options, but 1.1 is not yet known to be broken. Disabling 1.1 may mitigate attacks against some broken TLS implementations.
