Frequently Asked Questions

What is AES encryption?

AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used to secure data. It uses the same key for both encryption and decryption.

Is my encryption key safe?

Yes, all encryption and decryption happens locally in your browser. Your key and data are never sent to any server.

What algorithms are supported?

The tool supports AES, DES, 3DES, RC4, and Rabbit. AES is the most secure and recommended for general use.
