WebThe combination of the ChaCha20 stream cipher with the Poly1305 authenticator was proposed in January 2014 as an alternative to the Salsa20-Poly1305 construction. ChaCha20-Poly1305 was implemented in major operating systems, web browsers and crypto libraries shortly after. It eventually became an official IETF standard in May 2015. WebMar 8, 2024 · Mode of Operation. We don't use AES as it is since it is primitive, however, ChaCha20 is designed in CTR mode. We need a mode of operation for AES, too. The most common ones AES-GCM and ChaCha20-Poly1305. Poly1305 uses Z / ( 2 130 − 5) Z and is easy to implement in software without timing side channels.
