[openssl-users] OpenSSL patch for CHACHA cipher support in OpenSSL 1.0.2

[Srivalli Kuppa (srikuppa)]

Interesting. Yes, I did take a look at Cloudflare patch but wasn't sure if I could use that.
Alright. This helps. 

My only option is to upgrade to OpenSSL 1.1.0 in order to support CHACHA+Poly1305 cipher support.

Thanks Rich.

    It can be done; CloudFlare posted some patches at https://github.com/cloudflare/sslconfig/tree/master/patches but I think they used the pre-IETF version and so might need some tweaks.  The OpenSSL project won't do it (we don't add features to existing releases).
