Encrypt & Decrypt

Everything happens in your browser. We never see your plaintext, your key, or your ciphertext. Open source. Auditable. Trustless.

Encryption You Can Trust

🛡️

AES-256-GCM

Authenticated encryption with associated data. Tamper-proof ciphertext with built-in integrity verification.

🧠

PBKDF2 Key Derivation

600,000 iterations of PBKDF2-SHA256 transforms your passphrase into a hardened 256-bit key. Brute force is futile.

🌐

Web Crypto API

Built on the browser's native cryptographic primitives — no third-party libraries. Hardware-accelerated where available.

🚫

Zero Server Contact

Your plaintext, passphrase, and ciphertext never leave the browser tab. Nothing is transmitted. Ever.

❄️

Unique Salt & IV

A fresh random salt and initialization vector is generated for every encryption. Same input, different output every time.
