国密证书生成实践
实验环境:
1

|
Linux ubuntu/Centos 64 x86_64 x86_64 x86_64 GNU/Linux |
1、根据官网说明安装gmssl

5
|
$ unzip GmSSL-master.zip $ cd GmSSL-master $ . /config no-saf no-sdf no-skf no-sof no-zuc no-shared #不去编译动态库,编译出来的gmssl不再依赖libssl.so $ make $ sudo make install |
2、修改/usr/local/ssl/openssl.cnf配置
1
|
$ vi /usr/local/sslopenssl .cnf |
1

4
|
[ ca ] default_ca = CA_default # The default ca section [ CA_default ] #dir = ./demoCA # Where everything is kept dir = /home/myapp/demoCA #此处修改 |
3、初始化CA目录
1)创建根目录
1
2
|
$ mkdir -p /home/myapp/demoCA $ cd /home/myapp/demoCA |
2)创建其他目录
在此路径下要创建好/usr/local/ssl/openssl.cnf中需要的certs, crl ,new_certs_dir和private_key的子目录,默认是newcerts和private
1
|
$ mkdir certs crl newcerts private |
3)创建好database文件index.txt
1
|
touch index.txt |
4)创建好serial文件,并写入初始序号,如01
1
|
echo "01" > serial |
4、生成国密证书步骤
(1)生成根证书
1)生成私钥key
1
|
$ gmssl ecparam -genkey -name sm2p256v1 -text -out Root.key -config /usr/local/ssl/openssl .cnf |
2)生成证书签名请求
1
2
|
$ gmssl req -new -key Root.key -out Root.req -subj /C =CN /ST =Guang\ Zhou /L =GZ /O =Root /OU =Root\ Sign /CN =RootCA /emailAddress =Root@gmail.com -config /usr/local/ssl/openssl .cnf |
3)生成根证书
1
2
|
$ gmssl x509 -req -days 3650 -sm3 - in Root.req -signkey Root.key -out RootCA.crt $ cp RootCA.crt demoCA/ $ cp Root.key demoCA /private/ |
类似于 apache/ssl/ca.crt和apache/ssl/ca.key
(2)生成中间证书(即客户端证书)
1)生成私钥
1
|
$ gmssl ecparam -genkey -name sm2p256v1 -text -out Medium.key -config /usr/local/ssl/openssl .cnf |
2)生成客户证书请求
1
|
$ gmssl req -new -key Medium.key -out Medium.req -subj /C =CN /ST =Guang\ Zhou /L =GZ /O =Medium /OU =Medium\ Sign /CN =MediumCA /emailAddress =Medium@gmail.com -config /usr/local/ssl/openssl .cnf |
3)签发证书
1
|
$ gmssl x509 -req -sm3 -days 3650 -CA RootCA.crt -CAkey demoCA /private/Root .key -CAcreateserial - in Medium.req -out MediumCA.crt |
4)证书验证
1
|
$ gmssl verify -CAfile RootCA.crt MediumCA.crt |
1
2
|
$ cp MediumCA.crt demoCA/ $ cp Medium.key demoCA /private/ |
5)证书转换成浏览器认识的格式 pfx
1
|
$ gmssl pkcs12 - export -inkey Medium.key - in MediumCA.crt -out test .pfx -passin pass:xxx -passout pass:xxx |
6) 查看证书信息

11
|
PKCS转换为PEM gmssl pkcs12 - in test .pfx -out cert.pem -nodes 转换后可查看证书信息 打印出证书的内容: gmssl x509 - in cert.pem -noout -text 打印出证书的系列号 gmssl x509 - in cert.pem -noout -s erial 打印出证书的拥有者名字 gmssl x509 - in cert.pem -noout -subject 打印出证书的MD5特征参数 gmssl x509 - in cert.pem -noout -fingerprint |
(3)生成服务器证书
1) 生成私钥
1
|
$ gmssl ecparam -genkey -name sm2p256v1 -text -out Server.key -config /usr/local/ssl/openssl .cnf |
2) 证书请求
1
|
$ gmssl req -new -key Server.key -out Server.csr -subj /C =CN /ST =Guang\ Zhou /L =GZ /O =Server /OU =Server\ Sign /CN =ServerCA /emailAddress =Server@gmail.com -config /usr/local/ssl/openssl .cnf |
3) 签发证书
1
|
$ gmssl x509 -req -sm3 -days 3650 -CA RootCA.crt -CAkey demoCA /private/Root .key -CAcreateserial - in Server.csr -out ServerCA.crt |
4)证书验证
1
|
$ gmssl verify -CAfile RootCA.crt ServerCA.crt |
