About TLS 1.2 support in openssl
openssl
Solution
Yes.
"Support TLS v1.2 and TLS v1.1." -- https://www.openssl.org/news/openssl-notes.html
Problem
Does openssl 1.0.1c (the latest stable version that I can find on the www.openssl.org) fully support TLS 1.2? I have searched all the changelogs about openssl. Unfortunately, I can not find the information such as "fully support TLS 1.2". It just mentioned "Initial TLS v1.2 support" in the "changes between 1.0.0h and 1.0.1".
