AES是一种可用来保护电子数据的新型加密算法。特别是，AES是可以使用128、192和256位密钥的迭代式对称密钥块密码，并且可以对128位(16个字节)的数据块进行加密和解密。-AES is a new encryption algorithm to protect one of the available electronic data. In particular, AES may be used for 128, 192, and 256-bit key iterative symmetric key block cipher, and can encrypt and decrypt the data block of 128 bits (16 bytes).
