Encrypt and decrypt text with a password.

How to use AES-256 Encryption

Protect text with a password using the Auvatrix envelope.

  1. Select Load example or paste your own test input.
  2. Choose Encrypt / Decrypt and review the available options.
  3. Run the selected action; review any validation message.
  4. Inspect the output before copying, printing or downloading it.

A small example

Encrypt “private note” with a 12+ character password, then decrypt the resulting JSON

When the result looks wrong

Keep the entire envelope. A forgotten password cannot be recovered. Other AES tools may use incompatible formats.

Questions about AES-256 Encryption

Is my input uploaded?

File and text processing runs in your browser. Opening the website still loads application assets from its host.

What if the result looks wrong?

Keep the entire envelope. A forgotten password cannot be recovered. Other AES tools may use incompatible formats.

Can I use sensitive production data?

Prefer non-sensitive test data. Never paste live access tokens, passwords or confidential documents into a site without assessing its code and environment.
