Before adding a new GPG key to your GitHub account, you should have:
GitHub supports several GPG key algorithms. If you try to add a key generated with an unsupported algorithm, you may encounter an error.
When verifying a signature, we extract the signature and attempt to parse its key-id. We match the key-id with keys uploaded to GitHub. Until you upload your GPG key to GitHub, we cannot verify your signatures.
