How to Decrypt a GPG File with a Passphrase in Python
Decrypt a GPG-encrypted file using a passphrase via the gpg CLI wrapped in a reusable Python function.
import subprocess
import tempfile
from pathlib import Path
def decrypt_gpg_file(input_file: str, passphrase: str) -> str:
"""Decrypt a GPG file using a passphrase and return the plaintext."""
result = subprocess.run(
["gpg", "--batch", "--yes", "--passphrase", passphrase, "--decrypt", input_file],

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