I wanted to dump the headers for a http request over ssl today. Pulled out socat and this command and it seemed to work quite nicely.
You will need to create server.crt and server.key and if you don't want the other end to complain then they should be a valid keypair.
Socat is a really nice tool that exposes the power of Unix sockets and allows you to connect anything together. In this case a tcp socket with ssl support and the standard out. But it could be a UDP port and a serial cable for all all socat cares. A really nice tool.
