Getting Started

This guide walks you through downloading Qpher Vault, creating your account, and encrypting your first file.

Requirements​

  • iPhone or iPad running iOS 17 or later
  • An email address for account creation

Step 1: Download Qpher Vault​

Download Qpher Vault from the App Store:

Step 2: Create Your Account​

  1. Open the app and tap Sign Up
  2. Choose your sign-up method:
    • Email + Password — enter your email and create a strong password
    • Sign in with Apple — one-tap sign up with your Apple ID

Step 3: Verify Your Email​

If you signed up with email, you'll need to verify it:

  1. Check your inbox for the verification email from Qpher
  2. Tap the verification link
  3. Return to the app — your account is now verified
Didn't receive the email?

Check your spam folder. You can also tap "Resend" in the app to send a new verification email.

Step 4: Encrypt Your First File​

Once your account is set up, you'll see an empty document list:

  1. Tap the + button in the top-right corner
  2. Select Encrypt File
  3. Choose a file from your device (photo, PDF, document, etc.)
  4. The file is automatically encrypted and stored in your vault

That's it! Your file is now protected with quantum-safe encryption.

What Happens During Encryption?​

When you encrypt a file, Qpher Vault:

  1. Generates a random AES-256-GCM encryption key (DEK)
  2. Encrypts your file with the DEK
  3. Wraps the DEK using X-Wing KEM (post-quantum key encapsulation)
  4. Uploads the encrypted file to secure cloud storage
  5. The private key stays in the server-side KMS — it never touches your device
Your keys are safe

Private keys never leave the server-side secure environment. Even if your device is compromised, your encryption keys remain protected.
