`Verify return code: 0 (ok)` means yes... you could also check ssllabs — Jacob Evans, Nov 25 '16 at 17:28
you forced the connection over tls 1.2, so it's works, but there's no cert — Jacob Evans, Nov 25 '16 at 17:30
Thanks a lot Jacob! The other ssllabs is a pretty amazing tool! — marafado88, Nov 25 '16 at 17:42

Partially, the server support TLS 1.2 but you didn't send a cert to actually do the encryption.

Also TLS1.2 was standards in 2008.
