OrigamiVault

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.
