Shared-Key Signature
Question
I know that most uses of cryptographic signatures are with public/private keys, but I need to sign information using a pre-shared key. I know I can just encrypt the data, but I prefer signing it..
Is it possible in C#?

HMAC is the usual shared key signing algorithm, and it is doable in c#

there are plenty of schemes (involving HMAC) to perform message signature with symmetric (pre-shared) key material.
