完整流程

 生成密钥对

• 1，本地首先使用openssl生成一个256位的SM2私钥
  • ​gmssl ecparam -genkey -name sm2p256v1 -text -out xxxx.key
    • 查看私钥内容
    • gmssl sm2 -noout -text -in xxxx.key 
    • 或者
    • gmssl pkey -in xxxx.key -text

gmssl sm2 -noout -text -in xxxx.key 
Using configuration from /usr/local/gmssl/openssl.cnf
read SM2 key
Private-Key: (256 bit)

生成P10 

• 2，基于密钥产生证书申请（P10 = 公钥 + 字段）
  • gmssl req -new -sm3 -key xxxx.key -out xxxx.req -subj "/C=Cn/ST=Hubei/L=Wuhan/O=kk/OU=kkk/CN=client/[email protected]"
  • 查看申请内容
    • gmssl req -nout -in xxxx.req -text

生成双证书 

• 3 从吉大正元的PKI进行证书下载，证书的相关字段和请求保持一致，进行证书下载阶段时，上传先前产生的P10数据

• 选择 自定义P10申请
• 申请书内容 填写  xxxx.req，但是需要去掉 -----BEGIN CERTIFICATE REQUEST----- 和 -----END CERTIFICATE REQUEST-----
• 证书类型，这里选择zip，但是zip解压得到的以下三个文件，分别是P7b格式的签名和加密证书，private.data 是 加密之后的与加密证书相对应的私钥
  • 注意事项：
    • 本地产生私钥的时候，同时产生与之对应的公钥
    • 公钥+数据字段 --> 获取申请请求
    • 私钥和签名证书相对应
    • 加密证书是包含公钥的，其对应的私钥被加密保护，也就是private.data

•  将cer格式的证书修改后缀名为pem，将其导入到Ubuntu，使用openssl进行读取
  • gmssl x509 -noout -text -in sign.pem

gmssl x509 -noout -text -in sign.pem
