From fa46b41af42797dba8dcd04b8cacbc78d602ab80 Mon Sep 17 00:00:00 2001
From: Christian Heimes <cheimes@redhat.com>
Date: Wed, 24 Jan 2024 09:23:22 +0100
Subject: [PATCH 1/2] Compatibility fix for PyCA cryptography 42.0.0
Cryptography 42.0.0 introduced two new abstract properties
`not_valid_before_utc` and `not_valid_after_utc`, which are non-naive UTC
variants of the `not_valid_before` and `not_valid_after` properties.
The old properties are deprecated. The changeset also modifies code and
tests to use the new `_utc` variants.
Fixes: https://pagure.io/freeipa/issue/9518

Use IPA's x509 module instead of `cryptography.x509`. This fixes a
regression which was introduced in commit a45a7a20.
