SM2算法，国家密码管理局公布的商用密码算法，关于椭圆曲线加密及签名的文档。-SM2 algorithm, published by the State Administration password commercial cryptographic algorithms, elliptic curve cryptography and signature on the document.

国家密码管理局规定的密码杂凑函数SM3代码，包括SM3.cpp, SM3.h, handle.c-State Encryption Administration under the cryptographic hash function SM3 code, including SM3.cpp, SM3.h, handle.cpp

国密SM3是国家密码局颁布的Hash值计算算法，在国内被逐渐的广泛使用，这里是其的C语音的实现-The secret SM3 is issued by the State Password Administration Hash value calculation algorithm, is widely used gradually in China, here is the realization of the C speech

SM2 C语言实现，通过国家密码管理局的大数选择和参数定义要求(SM2 C language implementation, through the national Password Administration's large number selection and parameter definition requirements)
