From 2f5590bf38e5995a36f770c04cfbf31eb9070eca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Damir=20Jeli=C4=87?= Date: Tue, 18 Jun 2019 13:46:57 +0200 Subject: olm: Allow decryption functions to define how to handle unicode decode errors. This patch changes the decryption functions not to fail if there was an unicode decode error while converting the decrypted bytes plaintext into a native python string. Characters that cannot be decoded as unicode are now replaced with the unicode replacement character (U+FFFD). The old behaviour of raising an UnicodeDecodeError can be achieved by passing the "strict" error handling scheme to the decrypt function. --- python/tests/pk_test.py | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'python/tests/pk_test.py') diff --git a/python/tests/pk_test.py b/python/tests/pk_test.py index fe3b4b6..749d2eb 100644 --- a/python/tests/pk_test.py +++ b/python/tests/pk_test.py @@ -1,3 +1,6 @@ +# -*- coding: utf-8 -*- +from builtins import bytes + import pytest from olm import (PkDecryption, PkDecryptionError, PkEncryption, PkSigning, @@ -55,3 +58,10 @@ class TestClass(object): message = "This statement is true" signature = signing.sign(message) ed25519_verify(signing.public_key, message, signature) + + def test_invalid_unicode_decrypt(self): + decryption = PkDecryption() + encryption = PkEncryption(decryption.public_key) + message = encryption.encrypt(bytes([0xed])) + plaintext = decryption.decrypt(message) + assert plaintext == "�" -- cgit v1.2.3 From 28350d612e4f2cbb7cdf3187a871a0e9f3c04724 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Damir=20Jeli=C4=87?= Date: Thu, 20 Jun 2019 13:38:35 +0200 Subject: tests: Use Unicode literals in the Unicode decoding tests.
