Git Signing in Python

Sign and verify Git commits with a mock GPG implementation using HMAC and SHA-256.

git signing hmac
Python
import hashlib
import hmac

class GPGMock:
    def __init__(self, secret_key):
        self.secret_key = secret_key.encode()

    def sign_commit(self, commit_message):
        """Mock GPG signing by computing an HMAC of the commit message."""
        signature = hmac.new(self.secret_key, commit_message.encode(), hash…
