Text Encryptor / Decryptor
Encrypt a message with a passphrase, share the result, and let the receiver paste it back to decrypt. AES-256-GCM, all in your browser.
Encrypted in your browser. Anyone you share this with needs the passphrase.
How it works
- Your passphrase is stretched with PBKDF2 (200,000 iterations, SHA-256) into an AES-256 key.
- Encryption uses AES-GCM with a per-message random nonce — same plaintext produces a different ciphertext every time.
- Output is URL-safe base64, ready to paste into chat, email, or a URL.
- Nothing leaves your browser. We never see, log, or store your message or passphrase.
