Encrypt text with a password or decrypt it back, using AES-GCM in your browser.
Encrypt text with a password or decrypt it back, using AES-GCM in your browser.
iv:ciphertext hex, safe to paste into chat or emailThe password is hashed with SHA-256 to make a 256-bit AES key. Each encryption uses a fresh random 12-byte IV and AES-GCM, which also detects tampering, and the result is written as iv:ciphertext in hex. Decryption splits the two parts and fails loudly if the password is wrong or the text was changed.
AES-GCM is strong, but the key comes from a single SHA-256 of your password, so security depends on the password. Use a long, unique passphrase.
No. There is no recovery; without the password the text cannot be decrypted.
No. Encryption and decryption run locally with the browser's Web Crypto API.
