开始:

       GMSSL最终编译好的路径:   F:workworkGmSSL-Win64

1. 在bin目录下新建文件夹，demoCA —-也可以建立在别的路径，个人喜好，无所谓，只要后面执行命令的时候指定路径

2. 在demoCA目录下分别建立文件夹：certs，crl，newcerts，private

3. 在demoCA目录下分别建立文件：index.txt, index.txt.attr, serial       —serial填入01起始序号，另外默认两个空文件

上述demoCA以及子目录下的各个文件夹以及文件名称都是来自

openssl.cnf默认配置项CA_default，初次不建议修改，直接照着来就好，高级玩家自便。。。

 4. 接下来便是执行一系列的命令了，生成sm2的证书.

cd到F:workworkGmSSL-Win64in目录下

ca私钥和证书   —– 此处ca的私钥cakey.pem以及证书的名字cacert.pem不建议修改，也是根据openssl.cnf来的，不然会报错， —-高级玩家自便

ca private key

gmssl.exe genpkey -algorithm EC -pkeyopt ec_paramgen_curve:sm2p256v1 -pkeyopt ec_param_enc:named_curve -out DemoCA/private/cakey.pem

ca cert

gmssl.exe req -new -x509 -key DemoCA/private/cakey.pem -out demoCA/cacert.pem

服务器私钥以及 csr， 公钥证书

server private key

gmssl.exe genpkey -algorithm EC -pkeyopt ec_paramgen_curve:sm2p256v1 -pkeyopt ec_param_enc:named_curve -out DemoCA/private/serverkey.key

server csr

gmssl.exe req -new -key DemoCA/private/serverkey.key -out demoCA/serverreq.csr

server cert

gmssl.exe ca -in DemoCA/serverreq.csr -out DemoCA/servercert.pem

此处有一个地方需要注意：

 在生成csr请求的时候，填入的Orgnizeation Name，红色部分，要与之前生成CA证书的时候保持一直，不然会报错，提示不匹配，生成的证书文件为空

剩下与服务端一样，只是名称不一样，其实也并非是服务器跟客户端之分，此处为了好分别，正常ca颁发的，证书合法，能通过校验就行。

客户端私钥以及 csr， 公钥证书 

device ipc key

gmssl.exe genpkey -algorithm EC -pkeyopt ec_paramgen_curve:sm2p256v1 -pkeyopt ec_param_enc:named_curve -out DemoCA/private/ipckey.key

ipc csr

gmssl.exe req -new -key DemoCA/private/ipckey.key -out demoCA/ipcreq.csr

ipc cert

gmssl.exe ca -in DemoCA/ipcreq.csr -out DemoCA/ipcreq.pem

命令执行生成完成后如下：
