I'm currently trying to create a chat based on the SslStream class. I was going through that msdn link: click here
I realized that I need to get an X509Certificate to establish that task. But I really don't know how can I get one? I know that there are ones who cost money, but there aren't free ones available?
P.S: I'm coming here after doing some search in google about that subject but haven't found any helpfull infomation.
So my question is: Where can I get an x509 certificate?
Thank you.
