Experience Self-Decrypting Files

The best way to understand Q-Archive is to use it. We encrypted a sample document so you can see exactly what your clients will experience.

Try It Yourself

We created this demo using Q-Archive. Follow the steps below to decrypt it - this is exactly what your clients will do.

What You'll Notice

Under 30 Seconds

Download, open, enter passphrase, done. Compare that to portal registration.

Works Anywhere

Try it on your phone, tablet, or any computer. No app installation required.

Works Offline

Turn off your wifi and try again. Decryption happens entirely in your browser.

How It Works (Technical)

AES-256-GCM Encryption

Your file is encrypted with the same algorithm used by banks and government agencies.

Argon2id Key Derivation

Your passphrase is strengthened using the winner of the Password Hashing Competition.

Self-Contained HTML

The encrypted file and decryption code are bundled together. Nothing is fetched from the internet.

Hidden Filename

Even the original filename is encrypted. Recipients don't see it until after decryption.

Passphrase Best Practices

Q-Archive's security depends on your passphrase. Here's how to share it safely:

Do

  • Share passphrase by phone call
  • Use a separate channel (text/SMS)
  • Use a pre-shared secret
  • Use strong, unique passphrases

Don't

  • Put passphrase in the same email
  • Use simple passwords like "123456"
  • Reuse passphrases across files
  • Share via unencrypted channels
