Main Question: When I hash a message to authenticate it, and then encrypt the hash result with a private key to make a digital signature, is the private key I'm using at that point (normally) a shared symmetric private key or my private key from my private/public key pair?
I'd say it's your private key from from your key pair.Yeah, sometimes words aren't the best medium for explaining things. If I could locate the nice diagrams in my cisco course materials, I'd scan it in and post it... but maybe these'll help out:
