Quantum-safe encryption is here. Protect your most sensitive documents with NIST-approved post-quantum cryptography — before quantum computers arrive.
Lawyers, consultants, and professionals trust Qpher Vault to encrypt and sign their most sensitive documents. Powered by NIST-standardized post-quantum cryptography (PQC), your files stay protected — today and for decades to come.
ENCRYPT WITH QUANTUM-SAFE CRYPTOGRAPHY
Every document is encrypted using ML-KEM-768 (FIPS 203), the quantum-resistant key encapsulation standard published by NIST in 2024. Traditional public-key encryption like RSA will be vulnerable to future quantum computers — Qpher Vault uses hybrid cryptography (X-Wing KEM) that combines classical and post-quantum algorithms, so your files are protected no matter what.
DIGITAL SIGNATURES
Sign documents with ML-DSA-65 (FIPS 204), a quantum-safe digital signature algorithm. Recipients can verify authenticity and detect any tampering — with cryptographic proof built to last.
SECURE SHARING
Share encrypted documents with anyone:
＊Direct sharing with granular permissions (View, Download, or Edit)
＊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
BUILT FOR REAL SECURITY
＊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 — your keys are isolated from application code
LOSE YOUR PHONE, NOT YOUR DATA
Unlike device-only encryption apps, Qpher Vault manages your private keys in our KMS infrastructure with hardware-backed key isolation. If you lose your phone, simply 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 lawyers handling email attachments or consultants managing client documents on the go.
FREE TO START
＊Free: 5 documents/month, 50 MB storage
＊Personal ($7.99/mo): Unlimited documents, 5 GB, digital signatures
POWERED BY QPHER PQC SECURITY CLOUD
Qpher Vault is built on the same enterprise-grade PQC infrastructure trusted by businesses worldwide. Every encryption and signature operation runs through Qpher's NIST-compliant cryptographic backend — ML-KEM-768 (FIPS 203) for encryption, ML-DSA-65 (FIPS 204) for signatures.
