Does openssl 1.0.2 support TLS1.0 TLS/.1and TLS 1.2?
If your server platform (or intermediate device) does not support TLS v 1.2, please make an upgrade plan. If your service provider does not support TLS v 1.2, ask them to upgrade. For those old clients, it is necessary to continue to support TLS v 1.0 and TLS v 1. 1. Use a temporary solution (as described below)
