Thanks Matt. Appreciate your answers. Just curious, is there a possibility to patch CHACHA cipher specific changes to OpenSSL 1.0.2 version still and get SSL handshake succeed? I am not looking for an upgrade to OpenSSL 1.1.0 at this point. So, I am interested to know if I can get CHACHA to working with OpenSSL 1.0.2. Thanks for your time. -Srivalli On 6/11/18, 11:59 AM, "openssl-users on behalf of Matt Caswell" <openssl-users-bounces@xxxxxxxxxxx on behalf of matt@xxxxxxxxxxx> wrote: On 11/06/18 16:44, Srivalli Kuppa (srikuppa) via openssl-users wrote: > 1.

No. Chacha/Poly1305 support is only available from version 1.1.0 upwards. > 2. Can CHACHA+Poly1305 ciphers be used with TLSv1.2 today with > different browsers (Chrome/Firefox etc.,)? Yes.
