Encrypt and share secrets via one-time links. End-to-end encrypted, auto-deleted, hosted in Germany. Passlocker lets you share passwords, API keys, and sensitive notes via one-time, self-destructing links — with zero-knowledge end-to-end encryption. 🛡️ Zero-Knowledge E2EE Your secrets are encrypted IN YOUR BROWSER using AES-256-GCM before they ever leave your device. The decryption key lives only in the URL fragment (#key) — it is NEVER sent to or stored on the server. Even the server administrator cannot read your secrets. This is the same zero-knowledge architecture used by PrivateBin and the former Firefox Send. 🔐 Key Features: • End-to-end encrypted (AES-256-GCM) — client-side, in your browser • Self-destructing links (limited views + time expiration) • Optional password protection (Argon2 hashed) • Right-click any selected text → instantly create a secure link • Auto-copy to clipboard with in-page confirmation toast • QR code generation for easy mobile sharing • No accounts, no login, no tracking, no ads • GDPR compliant — hosted in Germany (Hetzner) 🔗 How It Works: 1. Type or select a secret 2. Your browser encrypts it with AES-256-GCM (the key never leaves your device) 3. Only the ciphertext is sent to the server, wrapped in a second encryption layer (Fernet) 4. You get a link with the decryption key in the #fragment — never transmitted via HTTP 5. The recipient's browser decrypts client-side — the server never sees the plaintext 6. After viewing or expiration, the secret is permanently deleted 💡 Dual Encryption: Layer 1: Client-side AES-256-GCM (zero-knowledge E2EE) Layer 2: Server-side Fernet envelope (AES-128-CBC + HMAC-SHA256) 🖱️ Two Ways to Use: • Extension popup: paste your secret, configure views/expiration, generate link • Right-click context menu: select any text on a page → "Share via Passlocker" 🌐 Full integration with passlocker.busirus.com Open-source backend available for self-hosting.
