According to http://googleonlinesecurity.blogspot.com/2014/04/speeding-up-and-strengthening-https.html:
To make this happen, [we] began implementing new algorithms -- ChaCha 20 for symmetric encryption and Poly1305 for authentication -- in OpenSSL and NSS in March 2013. But I have not been able to find its trail: $ cd openssl-git $ git pull Already up-to-date. $ grep -R -i chacha * $ grep -R -i poly1305 * $ Where are the new cipher suites located in OpenSSL? Thanks in advance. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
