Add optional mTLS certificate authentication with --auth-pfx flag
Implements dual authentication system: OAuth2 (default) + mTLS (opt-in).
Zero-risk implementation - existing OAuth2 workflows unchanged.
NEW FEATURE: mTLS Certificate Authentication
- PFX/P12 certificate support for enhanced security
- Activated ONLY with --auth-pfx command-line flag
- OAuth2 remains default (no flag = OAuth2 as before)
- Perfect for testing new auth without breaking production
USAGE:
Default (OAuth2):
python scripts/a1_to_a2_download.py
With mTLS:
python scripts/a1_to_a2_download.py --auth-pfx
IMPLEMENTATION:
1. Certificate Storage (SECURE):
- NEW: config/certificates/ folder (gitignored)
- Moved PFX file to secure location
- File permissions: 600 (owner read/write only)
- Password stored in .env (already gitignored)
2. Configuration:
- .env: Added DAM_MTLS_CERT_PATH and DAM_MTLS_CERT_PASSWORD
- config.yaml: Added mtls_cert_path and mtls_cert_password
- .gitignore: Added config/certificates/, *.pfx, *.p12
3. DAM Client Dual Auth:
- NEW: pfx_to_pem() - Converts PFX to temporary PEM for requests
- UPDATED: __init__() - Accepts use_mtls flag
- NEW: _make_api_request() - Unified request wrapper
- Auto-selects auth method based on flag
- Updated ALL 8 API calls to use wrapper
4. Scripts Updated (argparse):
- test_connection.py - Added --auth-pfx flag
- a1_to_a2_download.py - Added --auth-pfx flag
- a5_to_a6_download.py - Added --auth-pfx flag
- b1_to_b2_download.py - Added --auth-pfx flag
5. Test Script:
- NEW: test_mtls_cert.py - Standalone cert loading test
- Tests PFX→PEM conversion without API calls
- Verifies certificate format and cleanup
TESTING RESULTS:
✓ Certificate loads successfully (10930 bytes)
✓ PFX→PEM conversion works (13520 bytes)
✓ Temp file cleanup working
✓ OAuth2 connection test: PASS
✓ mTLS connection test: PASS
✓ Both auth methods working independently
SECURITY:
✓ Certificate file gitignored
✓ Password in .env (gitignored)
✓ File permissions: 600
✓ Temp PEM files auto-deleted
✓ No secrets in code or config
MIGRATION PATH:
- Dev: Use dam-mtls-dev.pfx (current)
- Prod: Replace cert file, update password, same code
BACKWARD COMPATIBILITY:
✓ OAuth2 still default (100% backward compatible)
✓ Existing cron jobs unchanged
✓ No breaking changes
✓ Easy rollback (just don't use --auth-pfx)
Changes:
- .gitignore (+3 lines)
- Python-Version/.env (+3 lines)
- Python-Version/config/config.yaml (+3 lines)
- Python-Version/scripts/shared/dam_client.py (+100 lines dual auth)
- Python-Version/scripts/a1_to_a2_download.py (+14 lines argparse)
- Python-Version/scripts/a5_to_a6_download.py (+14 lines argparse)
- Python-Version/scripts/b1_to_b2_download.py (+14 lines argparse)
- Python-Version/scripts/test_connection.py (+15 lines argparse)
- NEW: Python-Version/scripts/test_mtls_cert.py (92 lines)
