AES Encryption
AES-GCM encryption with PBKDF2 — your text and passphrase never leave your browser
About this tool
Encrypt and decrypt text with AES-GCM and a passphrase, fully in your browser. Uses PBKDF2 key derivation and the Web Crypto API — your data and keys never leave your device. AES Encryption runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- AES Encryption is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
