AES Text Encryption
Encrypt or decrypt text with a password using AES-256-GCM. Share the result safely — only someone with the password can read it. Everything is computed in your browser with the Web Crypto API.

AES-256-GCM with a PBKDF2-SHA256 key (250,000 iterations). Encryption runs in your browser with the Web Crypto API — your text and password are never uploaded. There is no password recovery: if you lose the password, the text cannot be decrypted.
Frequently asked questions
Is the encryption secure?
Yes. It uses AES-256-GCM — the same authenticated cipher trusted for government and banking data — with a key derived from your password using PBKDF2-SHA256 over 250,000 iterations. The strength then depends on your password, so use a long, random one.
Is my text or password uploaded?
No. Encryption and decryption happen entirely in your browser with the Web Crypto API. Your text and password never leave your device, and nothing is stored.
I lost my password — can I still decrypt?
No. There is no backdoor or recovery: without the exact password the ciphertext cannot be decrypted. Keep the password safe, ideally in a password manager.
