Top Tips for Integrating KeePass Favicon Downloader with Your Vault

• Use requests or httpx to fetch a site’s HTML.
• Parse for , manifest.json icons, or fall back to /favicon.ico.
• Download and validate images (check MIME type, dimensions).
• Save to a local folder named by domain.
• Optionally, convert or resize using Pillow and inspect before importing into KeePass.

Security tips:

• Run the script behind a privacy proxy or VPN if you don’t want direct site requests.
• Inspect and validate downloaded files; reject non-image MIME types.
• Keep the script run interactively so you can approve icons.

Step 5 — Proxying, sandboxing, and other privacy mitigations

• Use a SOCKS proxy or VPN when fetching icons to hide your real IP.
• Use a local HTTP proxy that strips identifying headers (User-Agent, Referer).
• Run fetching tools in a sandboxed VM or container to contain potential malicious files.
• Disable JavaScript and other active content when opening sites just to fetch icons.

Step 6 — Inspecting and validating icon files

Always validate before adding to your KeePass database:

• Confirm file type (PNG/ICO/SVG) and image headers.
• Reject files with unexpected MIME types or executable content.
• Resize/convert to standardized sizes (16×16, 32×32) if desired.
• Optionally open in an image viewer that does not execute embedded scripts.

For SVGs, prefer rasterizing to PNG to avoid any scripting vectors.

Step 7 — Automating import into KeePass

• KeePass allows custom icons per entry; many plugins offer bulk import.
• For a manual script, export icons into a folder and then use KeePass’s icon import dialog to add them to the database icon set.
• Keep a backup of your KeePass database before doing large-scale icon imports.

Step 8 — Ongoing maintenance and security hygiene

• Periodically review icons for changes or suspicious updates.
• Remove automated fetching for high-risk accounts.
• Keep KeePass and any plugins up to date.
• Maintain backups of your database before making batch changes.

Example checklist for a secure favicon workflow

• Decide threat model (manual vs automated).
• Use trusted plugins or local scripts only.
• Route requests through a VPN/proxy if needed.
• Validate file type and size before import.
• Import icons into KeePass and keep backups.

Conclusion

Favicons improve KeePass usability, but fetching them can leak information or introduce risks if done carelessly. Choose a workflow that matches your privacy needs: manual download for strict privacy, vetted local plugins or scripts for convenience, and always validate files and run tools in sandboxed environments when possible.

If you want, I can provide:

• A ready-to-run Python script to fetch and validate favicons locally.
• Step-by-step instructions for a specific KeePass plugin (name it).
