AES Encrypt Text

Encrypt text with AES-GCM using a passphrase-derived key created locally in your browser.

1) Add inputs
Paste the text, payload, signature, or key material needed for this cryptography task.
2) Set options
Choose the key size, iteration count, encoding, or signature settings you need.
3) Copy result
Keep the generated output for later use in your app, test data, or workflow.
Higher values slow attackers down, but also make encryption and decryption slower.
