AES Encryption

Encrypt and decrypt text with a password (AES-256).

Mode

AES-256-GCM with a key derived from your password (PBKDF2-SHA-256, 250,000 iterations, random salt and IV). Everything happens in your browser. If you forget the password, the text can't be recovered.

How to use

  1. 1Choose Encrypt and type your text.
  2. 2Enter a strong password.
  3. 3Copy the encrypted text and share it.
  4. 4The other person chooses Decrypt and uses the same password.

Frequently asked questions

How secure is it?

It uses AES-256-GCM with a key derived from your password by PBKDF2-SHA-256 (250,000 iterations) and a random salt and IV. Security depends on a strong password.

What if I forget the password?

The text can't be recovered. There is no backdoor.

Can I decrypt in another tool?

The output is base64url of version | salt | IV | ciphertext. Other tools need the same format and parameters.

Why does the output change each time?

A new random salt and IV are used every time, so the same text never encrypts the same way.

Is my data uploaded?

No. Everything runs in your browser; nothing you paste is sent to a server.
