From 29001b02a55354d3647d3bd9a05d5b1820d581d8 Mon Sep 17 00:00:00 2001 From: l3ocho Date: Tue, 29 Jul 2025 15:06:11 -0400 Subject: [PATCH] Complete Task 1.3 - Authentication System Implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit โœ… Implemented comprehensive authentication system: - Abstract AuthHandler base class with pluggable architecture - APIKeyAuth for API key authentication (string auto-conversion) - JWTAuth for JWT token authentication with expiration handling - NoAuth for testing and public instances - Full integration with WikiJSClient for automatic header management ๐Ÿ”ง Fixed packaging issues: - Updated pyproject.toml with required project metadata fields - Fixed utility function exports in utils/__init__.py - Package now installs correctly in virtual environments ๐Ÿงช Validated with comprehensive tests: - All authentication methods working correctly - Proper error handling for invalid credentials - Type validation and security features ๐Ÿ“Š Progress: Phase 1 MVP Development now 60% complete ๐ŸŽฏ Next: Task 1.4 -
