stunnel

NOTE: The title is misleading. Please correct it if you know a better title. What I want to know is how do I create the SSL keys / certificates needed for this.

Hi. I am using stunnel to authenticate RDP (Remote Desktop) and I need to verify that a client possesses the proper credentials. So people cannot brute force into the machine. I am also using a bad (outdated) version of RDP that has security vulnerabilities, so stunnel is a must.

I will preshare the necessary .pem's between machines.

What are the openssl commands I need to create the right .pem files on both the client and on the server? What files need to be shared?
