Enter a passphrase and text below — AES-256-GCM encryption runs in your browser. Output uses base64(salt:iv:ciphertext) with a unique random salt per encryption. This is a convenience tool only — not for production secrets, regulated data, or long-term archival. Use a strong passphrase; browser-based PBKDF2 has practical limits compared to dedicated key-management systems.
