Python _decrypt_aesgcm Examples

Example #1

def test_decrypt_aesgcm_truncated(ciphertext_len):
    # Check that grossly truncated ciphertexts still give the same error, and not something else.
    key = bytes.fromhex(

    nonce = bytes.fromhex("f5a57de46ff8daee400942c5")
    with pytest.raises(NoiseError):
