AES, or Advanced Encryption Standard, is a widely used encryption algorithm that ensures the confidentiality and integrity of data. It works by encrypting data into an unreadable format, which can only be decrypted with the corresponding decryption key. AES keys are used to encrypt and decrypt data, and their length can vary, with 128-bit, 192-bit, and 256-bit keys being the most common. 3ds aes keys
