Shangmi

A suite of authentication, encryption, and hash algorithms from the People's Republic of China.

国密即国家商用密码管理办公室认定的国产密码算法。主要有SM1，SM2，SM3，SM4。密钥长度和分组长度均为128位。
国密算法是指国家密码管理局认定的一系列国产密码算法，包括SM1-SM9以及ZUC等。其中

SM1、SM4、SM5、SM6、SM7、SM8、ZUC等属于对称密码
SM2、SM9等属于公钥密码 (非对称加密)
SM3属于单向散列函数

其中SM1、SM7算法不公开，调用该算法时，需要通过加密芯片的接口进行调用
