## What is Qpher Vault?

Your passport scan. Your tax records. Your client contracts.
Quantum-safe encryption for the documents that matter most — built for lawyers, consultants, and professionals.

QUANTUM-SAFE FILE ENCRYPTION
Every document is encrypted using ML-KEM-768 (FIPS 203), the quantum-resistant key encapsulation standard NIST published in 2024. Traditional public-key encryption like RSA will be broken by future quantum computers — Qpher Vault uses hybrid cryptography (X-Wing KEM) combining classical and post-quantum algorithms, so your files are protected today and for decades to come.

DIGITAL SIGNATURES
Sign documents with ML-DSA-65 (FIPS 204), the quantum-safe digital signature standard. Recipients can verify authenticity and detect any tampering — with cryptographic proof built to last.

SECURE SHARING
Send encrypted documents to anyone:
＊Direct sharing with granular permissions (View only or View & Download)
＊Recipients decrypt with their own Qpher keys — no passwords to remember or lose
＊Invitation-based sharing: non-users receive an email invite and get access after signing up

REAL SECURITY, BY DESIGN
＊Face ID / Touch ID biometric lock with Secure Enclave key protection
＊Auto-lock when you leave the app
＊Certificate pinning prevents man-in-the-middle attacks
＊App Attest integrity verification — tampered apps are rejected
＊Private keys managed by Qpher KMS with Cloud KMS envelope encryption — isolated from application code

LOSE YOUR PHONE, NOT YOUR DATA
Unlike device-only encryption apps, Qpher Vault manages your private keys with hardware-backed key isolation. Lose your phone? Sign in on a new device — all your documents are still accessible. No seed phrases, no recovery codes, no stress.

ENCRYPT FROM ANY APP
Use the Share Extension to encrypt files directly from Mail, Files, Photos, or Safari — no need to open Qpher Vault first. Ideal for handling email attachments or managing client documents on the go.

FREE TO START
＊Free: 50 MB storage, 5 MB max file size, 5 encryptions/shares/exports per month
＊Personal ($7.99/month or $79.99/year): 5 GB storage, 10 MB max file size, 50 encryptions/shares/exports per month, digital signatures
＊Personal Pro ($19.99/month or $199.99/year, 7-day free trial): 10 GB storage, 25 MB max file size, 200 encryptions/shares/exports per month, digital signatures

POWERED BY QPHER PQC SECURITY CLOUD
Qpher Vault runs on the same enterprise-grade post-quantum cryptographic infrastructure as our SaaS API platform — NIST-compliant ML-KEM-768 (FIPS 203) for encryption, ML-DSA-65 (FIPS 204) for signatures.
