SM2算法参数及用法说明文档，这是国密算法基础文档，里面包括各种详细说明-Cryptography development necessary documents, there is a detailed parameters and instructions

基于openssl的sm2和sm3实现，但是sm3的效率较低，不过对于学习来说是个不错的学习代码。基于此代码完全可以实现密钥对的生成。(Based on the openssl sm2 and sm3 achieved, but the efficiency is low sm3, but for learning is a good learning code. Based on this code can achieve key pair generation)
