AES Encrypt / Decrypt

Encrypt or decrypt text in the browser with AES-GCM, AES-CBC, or AES-CTR using a password-derived key or a raw hex key.

AES Encrypt / Decrypt Tool

The AES encryption tool runs AES-GCM, AES-CBC, and AES-CTR locally in the browser with support for password-derived keys and raw hex keys, which is useful for compatibility testing, encrypted payload checks, and local crypto debugging.

How do you use it?

  1. Choose encrypt or decrypt mode.
  2. Set the AES mode, key length, data format, and either a password-derived key or raw hex key.
  3. Enter plaintext or the full packed ciphertext and run the action.
  4. Copy the result and compare the displayed salt and IV if needed.

Features

  • Supports AES-GCM, AES-CBC, and AES-CTR
  • Supports password-derived and raw hex keys
  • Shows a packed result together with salt and IV metadata

Why use this tool?

  • Useful for checking whether frontend and backend AES parameters match
  • Helpful for debugging keys, modes, ciphertext formats, and PBKDF2 settings locally
  • Saves you from writing one-off scripts just to test encryption flows
