How to use this tool
Paste or type your input, adjust the options, then copy or download the result.
AES-GCM encrypt and decrypt in the browser
AES-GCM provides confidentiality and integrity. This page derives a key from your password with PBKDF2 and encrypts UTF-8 text. The ciphertext, IV and salt are packed as Base64.
Nothing is uploaded. Still, a browser tool is for small notes and experiments, not for a production KMS. Never reuse the same password on a public computer.
GCM fails closed if the password or ciphertext is wrong. That is a feature: tampering is detected.
