API Enhancements:
- Add SHA256 checksum endpoint for binary downloads
- Computes checksum on-the-fly when .sha256 suffix is requested
- Example: /download/pulse-host-agent?platform=linux&arch=amd64.sha256
- Enables installer scripts to verify binary integrity
- Add /uninstall-host-agent.sh endpoint for Linux/macOS uninstall script
- Add endpoint to public paths (no auth required)
Checksum Implementation:
- New serveChecksum() function computes SHA256 hash using crypto/sha256
- Returns plain text checksum in hex format
- Supports all binary download endpoints
- Zero performance impact (only computed when requested)
Install Script Updates:
- Add --force/-f flag to skip all interactive prompts
- URL/token prompts skipped with --force
- Reinstall confirmation skipped with --force
- Checksum mismatch still aborts (security first)
- Force mode auto-accepts updates and reinstalls
- Usage: ./install-host-agent.sh --url $URL --token $TOKEN --force
Security Notes:
- Checksum verification protects against:
- Corrupted downloads due to network issues
- Man-in-the-middle binary tampering
- Storage corruption on server
- Force mode maintains security by aborting on checksum mismatch
- No bypass for security-critical validations
These improvements enable:
- Automated deployments (--force flag)
- Binary integrity verification (checksums)
- Better security posture (tamper detection)
- Standardized uninstall process (endpoint)
The /api/version endpoint already exists and returns version info
for update checks (no changes needed).
