@mikhailswift looks like we're getting the golangci-lint issue again 🤦 |

* Initial link attestor Signed-off-by: John Kjell <john@testifysec.com> * refactor: move gitoid code to cyrptoutil, use digestvalue everywhere (#139) When the functionality to calculate gitoids was added, there was a bit of tech debt incurred since they didn't implement hash.Hash. This remedies this with an admitedly hacky implementation of hash.Hash that wraps the gitoid code. This also standardizes our cryptoutil fucntions around the DigestValue struct that was added around this time to differentiate between gitoids and regular hash functions.

This PR makes it possible to inspect the certificate attached to the signature (in the case that it was signed with x509 certificate) against user supplied cert constraints.
It should be noted that the constraint checks we perform is against any verifier that passes the initial policy verification logic. I am not sure whether this is an issue, but it is still something to be aware of. see here.
Another thing to note is that currently this logic has been broken out into a
verifyPolicySignaturefunction underneath the mainVerifyfunction. There may be a good place in the library to put this, but I couldn't think of one while working on it. Any suggestions on where we should put this would be most welcome.
