def test_prodkeys(keys_path, prodkey_path): keys = load_keys(keys_path) prod = load_prodkeys(prodkey_path) # Common test: decrypt a known sample ciphertext sample_encrypted = b"\x4d\x5a\x90..." # from documentation or working system try: decrypted = decrypt_asset(sample_encrypted, keys, prod) if decrypted.startswith(b"PK") or decrypted.startswith(b"\x7FELF"): print("SUCCESS: Keys appear correct") return True else: print("FAIL: Decryption produced garbage") return False except Exception as e: print(f"CRITICAL: e, keys are invalid or incompatible") return False
