Zero-Knowledge Architecture

Your secrets, locked by math.

PassCryp stores your passwords, API keys, secure notes, and credit cards in a vault encrypted platform. We literally can't read your data — and that's the point.

AES-256-GCM
No master password sent
No credit card to start
PassCryp shield

Everything you keep secret. In one place.

Designed for developers and privacy-conscious users who don't trust marketing copy — only architecture.

Zero-knowledge encryption

Your master password is never transmitted or stored — anywhere. Vault keys are derived locally in your browser with Argon2id and AES-256-GCM.

Password generator

Strong, configurable passwords from 8 to 64 characters. Save to vault in one click.

API key vault

Store AWS, Stripe, OpenAI keys with tags and expiry warnings. Auto-clear clipboard after 30s.

Credit cards on dashboard

Beautiful card widgets with auto-detected networks. CVV requires re-auth to reveal.

Browser extension

Auto-fill logins on any site. OAuth-based — your master password stays in the vault app.

MFA & SSO

TOTP, SMS, and SSO via Google, Apple, GitHub on the Pro plan.

Zero Trust Architecture

The math is the mandate.

Your data is encrypted on your device with a key derived from your master password. Only ciphertext ever touches our servers. We can't read it. A subpoena can't force us to read it. That's not a promise — it's how the system works.

  • AES-256-GCM authenticated encryption
  • PBKDF2 with 600k iterations key derivation
  • Per-row Row-Level Security in the database
  • TLS 1.3 in transit, encrypted at rest
  • Open security whitepaper coming soon
// On your device
const key = await deriveKey(masterPassword, salt);
const ciphertext = await encrypt(vault, key);
// Sent to PassCryp
POST /vault { ciphertext }
// Server sees: random bytes.
// We can't decrypt this. Ever.
