The SM4 cipher has a key size and a block size of 128 bits each. Encryption or decryption of one block of data is composed of 32 rounds. A non-linear key schedule is used to produce the round keys and the decryption uses the same round keys as for encryption, except that they are in reversed order. The length of encryption keys is 128 bits, represented as , in which is a 32-bit word. The round key… Webbsm4 . 功能: 使用SM4算法进行加密和解密,可以使用文件输入或者管道输入. 参数:-key SM4加密解密使用的长度为128bit的key,使用16进制表示-iv SM4加密使用的IV-encrypt …
