🔐 Choose Your Encryption Mode

Recommended: Key Mode - Experience true quantum-resistant security with cryptographic key pairs and access to 34 algorithms including 33 post-quantum and hybrid options. This is the future-proof choice for maximum protection against quantum computing threats. Password Mode derives the keys from your password with Argon2id and runs entirely in your browser; it is classical (X25519, Ed25519, AES-256-GCM), not quantum-resistant.

⚙️ Select Encryption Algorithm

In Password Mode, only Classical encryption is available using traditional X25519/Ed25519 algorithms. While reliable for basic use, Classical encryption is not quantum-resistant. For maximum security against future quantum threats, switch to Key Mode and use post-quantum algorithms.

✍️ Enter Your Data

Type or paste your plaintext message to encrypt, or paste encrypted data to decrypt. You can also upload files of any type - text, documents, images, videos, or archives.

Zero-knowledge, in your browser, for all 35 algorithms: Password Mode and Classical, Post-Quantum, Hybrid, ML-KEM-1024, Multi-KEM, Multi-KEM Triple, X25519MLKEM768, Multi-Algorithm, Quad-Layer, PQ3-Stack, Max Secure: Pure PQ, Max Secure: Hybrid Transition, Max Secure: Stateless and Max Secure: PQ Lightweight run as JavaScript engines, which also draw the ciphertext's byte map; every other algorithm runs as the platform's own Rust engine compiled to WebAssembly — the code the API runs — downloaded once, on first use. Keys are generated, and data encrypted and decrypted, in this page; the plaintext, the password and the private key never leave your device. Each algorithm's card says which engine runs it.

🔑 Create Your Password

Enter a strong password to encrypt your data. Remember this password - you'll need it to decrypt your data later. Use a mix of letters, numbers, and symbols for maximum security.

⚡ Encrypt or Decrypt Your Data

Click Encrypt to secure your data, or Decrypt to reveal encrypted content. The process uses quantum-resistant algorithms to protect your information. Results will appear below when complete.
