From c72ebf3da98d0e0a15bf01c95fea3b6d782ef3f7 Mon Sep 17 00:00:00 2001 From: Dan Guido Date: Tue, 5 Aug 2025 04:58:36 -0700 Subject: [PATCH] Fix certificate generation and improve version parsing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses multiple issues found during macOS certificate validation: Certificate Generation Fixes: - Add Basic Constraints (CA:FALSE) to server and client certificates - Generate Subject Key Identifier for proper AKI creation - Improve Name Constraints implementation for security - Update community.crypto to version 3.0.3 for latest fixes Code Quality Improvements: - Clean up certificate comments and remove obsolete references - Fix server certificate identification in tests - Update datetime comparisons for cryptography library compatibility - Fix Ansible version parsing in main.yml with proper regex handling Testing: - All certificate validation tests pass - Ansible syntax checks pass - Python linting (ruff) clean - YAML linting (yamllint) clean These changes restore macOS/iOS certificate compatibility while maintaining security best practices and improving code maintainability. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- main.yml | 11 +++++++++-- requirements.yml | 6 +++--- roles/strongswan/tasks/openssl.yml | 17 +++++------------ tests/unit/test_openssl_compatibility.py | 10 +++++++--- 4 files changed, 24 insertions(+), 20 deletions(-) diff --git a/main.yml b/main.yml index 75021819..18baae40 100644 --- a/main.yml +++ b/main.yml @@ -22,12 +22,19 @@ no_log: true register: ipaddr -
