I'm looking for Openssl's Chacha20/Poly1305 cipher support, supported client-side in Chrome/Chromium-dev, and server-side in Nginx. Last I was able to find on list [openssl-users] ChaCha20/Poly1305 in OpenSSL? Fri Mar 27 05:05:59 UTC 2015 https://mta.openssl.org/pipermail/openssl-users/2015-March/000934.html "... It appears we are also waiting on the cipher suite values. ..." but nothing more, afaict. Currently in 1.0.2f openssl version OpenSSL 1.0.2f 28 Jan 2016 openssl ciphers | grep -i chacha (empty) and there's no mention of it here, https://www.openssl.org/docs/man1.0.2/apps/ciphers.html but, in master https://www.openssl.org/docs/manmaster/apps/ciphers.html They're there ... ChaCha20-Poly1305 cipher suites from draft-ietf-tls-chacha20-poly1305-04, extending TLS v1.2 ... According to https://ianix.com/pub/chacha-deployment.html Chacha support is available now in LibreSSL, wolfSSL, BoringSSL, Botan, GnuTLS & for Openssl, "ChaCha support coming soon!" What's current plan status for these ciphers? Not until 1.1.0 release? Or earlier?
