AES Encryptor / Decryptor
Encrypt or decrypt text with AES-256-GCM and a passphrase.
Be careful what you paste. Don't run real secrets through any online tool — use locally-installed software for production keys.
About this tool
Encrypt arbitrary text with AES-256 in Galois/Counter Mode (authenticated encryption). The passphrase is stretched with PBKDF2-SHA256 (200k iterations). Output is base64-encoded for easy copy/paste.
