Hello,
Years ago, I posted about Cipherforge on Reddit and received mostly negative feedback because it wasn’t open source. The community was right to question trusting a closed-source security tool. Despite the criticism, I continued using it personally for my own needs and forgot about the rest. Since then, I’ve occasionally noticed traffic to the site (via Bunny.net stats, I don’t have analytics) and also received a few emails from users. These signals showed me that despite the initial reception, there was still interest in the concept, though it was low. Either way, I’m releasing Cipherforge as fully open source on GitHub! You can now audit the code, contribute improvements, or fork it for your own projects.
What is Cipherforge?
Cipherforge lets you transform sensitive text and small files into encrypted QR codes that can be printed and stored offline. It uses XChaCha20-Poly1305 encryption and runs entirely in your browser - no data ever leaves your device.
Why QR Codes?
- Physical, offline backup of critical secrets (passwords, certificates, keys)
- Air-gapped security for your most sensitive information
- No dependency on cloud services or electronic devices for storage
- Redundancy when all other backups fail
Key Features:
- 100% Open Source
- Completely offline operation
- XChaCha20-Poly1305 encryption
- Multiple security methods (password, key, or both)
- PDF export for easy printing

I appreciate all feedback and am happy to answer any questions!
