What is AES Encryption?
AES (Advanced Encryption Standard), originally known as Rijndael, is a symmetric-key encryption algorithm adopted by the U.S. government and used worldwide. It is the gold standard for encrypting sensitive data due to its high efficiency and security.
Symmetric encryption means the same key is used for both encryption and decryption. In modern applications, AES-256 (using a 256-bit key) is typically recommended for the highest level of security. This tool operates 100% on the client side, ensuring your data and keys never leave your browser.
