Qpher Vault: Encrypt Files

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 ＊Auto-lock when you leave the app ＊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 keeps your private keys in Qpher's key management service, not on your phone. Lose your phone? Sign in on a new device — all your documents are still accessible. No seed phrases, no key backups, 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, 10 encryptions and 5 shares per month ＊Personal ($7.99/month or $79.99/year): 5 GB storage, 100 MB max file size, 50 encryptions/shares/exports per month, digital signatures BUILT ON THE QPHER API Qpher Vault runs on the same post-quantum cryptographic infrastructure as the Qpher API. It implements NIST FIPS 203 (ML-KEM-768) for encryption and NIST FIPS 204 (ML-DSA-65) for signatures.
