What is AES?

AES (Advanced Encryption Standard) is a symmetric block cipher chosen by the U.S. government to protect classified information. It is used worldwide to encrypt sensitive data in software and hardware.

How it works

The tool uses CryptoJS to perform AES encryption. By default, it uses a password-based derivation (PBKDF2) if a string key is provided, generating a secure salted ciphertext compatible with OpenSSL.
