公钥秘钥使用sm2算法

根证书制作步骤：

1. 生成根证书秘钥
   openssl ecparam -out ca.key -name SM2 -genkey
2. 生成根证书请求文件
   openssl req -key ca.key -new -out ca.req
3. 生成根证书
   openssl x509 -req -in ca.req -signkey ca.key -out ca.pem

sm2证书制作步骤

1. 生成sm2秘钥对
   openssl ecparam -out site.key -name SM2 -genkey
2. 生成证书请求文件
   openssl req -key site.key -new -out site.req
3. 生成证书
   openssl x509 -req -in site.req -CA ca.pem -CAkey ca.key -out site.pem -CAcreateserial
4. 转为der格式
   openssl x509 -outform der -in site.pem -out site.der
