The upcomming OpenSSL 1.1.1 release will have TLS 1.3 support. TLS 1.3 brings a lot of changes that might cause incompatibility. For an overview see https://wiki.openssl.org/index.php/TLS1.3 We are considering if we should enable TLS 1.3 by default or not, or when it should be enabled. For that, we would like to know how applications behave with the latest beta release. When testing this, it's important that both sides of the connection support the same TLS 1.3 draft version. OpenSSL currently implements draft 26. We would like to see tests for OpenSSL acting as client and server. https://github.com/tlswg/tls13-spec/wiki/Implementations lists other TLS 1.3 implementations and the draft they currently support. Note that the versions listed there might not be for the latest release. It also lists some https test servers. We would really like to see a diverse set of applictions being tested. Please report any results you have to us. Kurt -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
