Where do I get an x509 certificate from?

Question

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.

Answer 1

You can create certificates with the makecert tool.

Or, if your're only interested in encrypting the traffic, without signing it, and you control the client and the server, just use a CryptoStream.
