Chore/update pre commit config (#14)

hemonserrat · web-flow · commit 818ac3ace1bd · 2025-09-12T22:30:43.000-07:00
* fix: update deprecated actions, add Docker support, and publish as gitsafe-cli

* security: replace manual CTR implementation with proper cryptography library

- Remove insecure manual CTR mode using ECB cipher
- Implement proper AES-256-CTR using cryptography library modes.CTR()
- Fix potential counter overflow and nonce reuse vulnerabilities
- Maintain backward compatibility with existing encrypted files
- All tests pass (110/110)

Fixes: Use of broken/weak cryptographic algorithm in crypto.py

* chore: update pre-commit config with modern Python tooling

- Update to latest hook versions (pre-commit-hooks v4.6.0, Black 24.8.0)
- Add Ruff, MyPy, and Bandit for comprehensive code quality checks
- Configure all tools to match project's pyproject.toml settings
- All hooks tested and passing
