Webb首先，将明文转化为字节，由于SM4加密算法按照128个位进行分组，所以很大几率会出现最后一个分组不够128位的情况，需要进行填充，填充方式有很多，比如ZeroPadding、PKCS7Padding、PKCS5Padding，不管使用哪种方式，最后每个分组都是128位。然后对每个分组执行上面的操作，每个分组按照32位一个字分成 ... WebbFor a more detailed introduction to SM cryptographic algorithms, please see Section 1.1.These cipher suites follow the TLS 1.3 requirements. Specifically, all the cipher suites use SM4 in either Galois/Counter (GCM) mode or Counter with CBC-MAC (CCM) mode to meet the needs of TLS 1.3 to have an encryption algorithm that is Authenticated …
