What is AES?

The Advanced Encryption Standard (AES) is a symmetric block cipher chosen by the U.S. government to protect classified information. Because it is symmetric, the exact same secret key used to encrypt the data must be used to decrypt it. Our tool processes everything locally, so your secret key and text are safe.

Is it safe and private?

Yes, absolutely. All processing is done locally within your web browser using JavaScript. Your data is never transmitted to or stored on our servers, ensuring 100% privacy and security.
