Are you talking about SSL/TLS certificates?

This sounds like telnet-over-TLS, which you’d have to authenticate via a TLS client certificate. I’m not sure if a standard (e.g., standard port) exists for that.

If you don’t need authentication, OpenSSL’s s_client can do what you want. Some netcat implementations (e.g., Eric Jackson’s rewrite) can do that, too.
