Share secrets publicly without risk
Vault's encrypted QR codes contain your data encrypted in portable format. Unlike traditional QR codes that contain readable information, Vault's QR codes store completely encrypted data with Argon2id + XChaCha20-Poly1305.
When you encrypt a message in Vault, the system generates a QR code that contains:
What it does NOT contain:
Print the QR and store it in a safe. Your seed phrase will be protected even if someone finds the printed code.
Post the QR on social media, forums, or messaging. Only those with the correct password can decrypt the content.
Save the QR on Google Drive, Dropbox, or any cloud service without worrying about security breaches.
Send the QR by postal mail, courier, or in person. The transport medium doesn't matter, your data is secure.
| Scenario | Traditional QR | Vault Encrypted QR |
|---|---|---|
| Someone scans the QR | Full access to data | Only sees useless encrypted data |
| QR posted on social media | Information exposed publicly | Completely secure, requires password |
| QR stolen or lost | Total security compromise | No risk, encrypted data |
| QR intercepted | Information readable immediately | Impossible to decrypt without password |
To recover information from an encrypted QR:
Vault also offers a Recovery Kit - a Node.js command-line tool that includes:
The Recovery Kit is perfect for long-term backups, as it doesn't depend on Vault being online or available in the future.
The security of encrypted QRs doesn't depend on keeping the QR secret. Even if someone has access to the QR, decrypting the content without the correct password is computationally impossible:
Your secrets are protected by mathematics, not by obscurity.
