# 制作serverKey.pem和serverCert.cer
	```
	openssl req -newkey rsa:2048 -nodes -keyout serverKey.pem \
	-x509 -days 365 -out serverCert.cer \
	-subj "/C=CN/ST=GD/L=GZ/O=abc/OU=defg/CN=hijk/emailAddress=132456.com"
	```

	# CentOS环境编译前需要安装开发工具
	```
	sudo yum groupinstall "Development Tools"
	sudo yum install cmake3 openssl-devel
	```

	# 编译步骤
	```
	cmake3 .
	make
	```

	-subj "/C=CN/ST=GD/L=GZ/O=abc/OU=defg/CN=server/emailAddress=server@132456.com"
	```

	# 验证
	```
	在第一个终端窗口运行
	openssl s_server -accept 4430 -key serverKey.pem -cert serverCert.cer

	在第二个终端窗口制作clientKey.pem和clientCert.cer，然后运行openssl s_client
	openssl req -newkey rsa:2048 -nodes -keyout clientKey.pem \
	-x509 -days 365 -out clientCert.cer \
	-subj "/C=CN/ST=GD/L=GZ/O=abc/OU=defg/CN=client/emailAddress=client@132456.com"
	openssl s_client -connect 127.0.0.1:4430 -key clientKey.pem -cert clientCert.cer

快速上手指南介绍GmSSL的编译、安装和gmssl命令行工具的基本指令。

下载源代码(zip)，解压缩至当前工作目录
```
$ unzip GmSSL-master.zip
```
编译与安装

Linux平台 (其他平台的安装过程见编译与安装)
```
$ ./config no-saf no-sdf no-skf no-sof no-zuc
$ make
$ sudo make install
```
安装之后可以执行gmssl命令行工具检查是否成功
```
$ gmssl version
GmSSL 2.0 - OpenSSL 1.1.0d
```

SM4加密文件

$ gmssl sms4 -e -in <yourfile> -out <yourfile>.sms4
enter sms4-cbc encryption password: <your-password>
Verifying - enter sms4-cbc encryption password: <your-password>

解密

$ gmssl sms4 -d -in <yourfile>.sms4
enter sms4-cbc decryption password: <your-password>

生成SM3摘要

$ gmssl sm3 <yourfile>
SM3(yourfile)= 66c7f0f462eeedd9d1f2d46bdc10e4e24167c4875cf2f7a2297da02b8f4ba8e0

生成SM2密钥并签名

$ gmssl genpkey -algorithm EC -pkeyopt ec_paramgen_curve:sm2p256v1 \
                -out signkey.pem
$ gmssl pkeyutl -sign -pkeyopt ec_scheme:sm2 -inkey signkey.pem \
                -in <yourfile> -out <yourfile>.sig

可以将公钥从signkey.pem中导出并发发布给验证签名的一方

$ gmssl pkey -pubout -in signkey.pem -out vrfykey.pem
$ gmssl pkeyutl -verify -pkeyopt ec_scheme:sm2 -pubin -inkey vrfykey.pem \
                -in <yourfile> -sigfile <yourfile>.sig

生成SM2私钥及证书请求

$ gmssl ecparam -genkey -name sm2p256v1 -text -out user.key
$ gmssl req -new -key user.key -out user.req

查看证书请求内容：

$ gmssl req -in user.req -noout -text -subject
