I know nothing about Certificates other than they're used for SSL. I've never had to deal with client certs and I am completely lost.
We have a legacy app that requires a client cert. A new vendor is trying to connect to this application. They issued the cert and sent it to us, but I'b having some trouble getting it to work. I've got IIS set up correctly, based on the many articles I've read.
A basic understanding of certs is making this more difficult than I think it should be, so I'm hoping someone can answer some of my questions:
1. They issued a .cer file. When installd on my client maching I don't seem to have a private key with it. Should there be?
2. What's the difference between a .pfx and .cer? I've tried googling this and the textbok answers don't help. Can a .cer have a private key, or is that only in a .pfx?
EDIT: One more question. The vendor sent us the client cert we should be using, it is issued by themselves. It's my understanding that I also need a Root cert from them to put into our Trusted Root store to go along with this, is that correct?
