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.

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). -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
