OrigamiVault
Encrypt and split secrets for printable offline paper recovery
OrigamiVault is a small offline web application for encrypting or splitting sensitive secrets and producing printable recovery artifacts. It generates QR codes and OCR-friendly decryption snippets so secrets can be stored on paper for long-term emergency recovery.
Key Features
- Client-side AES encryption using the browser Web Crypto API for password-based encryption
- Optional Shamir's Secret Sharing to split secrets into multiple shares
- Dual printable formats: compact QR codes and OCR-friendly JavaScript decryptor text (high-contrast mono font)
- Built-in QR scanner that runs in the browser for quick recovery
- Fully offline, static HTML/CSS/JavaScript implementation suitable for USB or static hosting
- No server, no analytics, and all cryptography performed locally
Use Cases
- Securely print master passwords, recovery phrases, or crypto keys for long-term archival
- Create split backups where different trusted parties hold complementary information for emergency recovery
- Produce OCR-friendly printed recoverable snippets as a resilient alternative to purely digital backups
Limitations and Considerations
- Security relies on the strength of chosen passwords and the physical protection of printed paper
- OCR accuracy and QR readability depend on print quality, font scaling, and camera/scanner conditions
- Not a multi-user vault or live secret manager; intended for one-off encrypted printouts and recoveries
OrigamiVault is a focused tool for physical, offline secret recovery workflows that emphasizes simplicity and auditability. It is best suited for archival backups and digital legacy scenarios where paper-based recovery is required.
