1.下载OpenSSL的windows版本
32位：openssl-1.0.2a-i386-win32.zip
64位：openssl-1.0.2a-x64_86-win64.zip
下载之后解压即可使用，不过软件缺少配置文件
2.建立配置文件
在解压后的目录, 即openssl.exe所在目录新建配置文件，名为openssl-1.0.2a.cnf，内容如下

# If you are using PKCS#11

init = 0
3.初始化一些参数
cmd切换到openssl目录，执行以下初始化内容
初始化内容包括，建立keys文件夹，生成index.txt空文本文件，生成serial文件内容为01
rmdir /s /q keys
mkdir keys
copy /Y nul keys\index.txt
echo 01 >keys\serial
SET HOME=.
SET KEY_DIR=keys
4.生成ca证书
这一步生成了2个文件：ca.key为CA的私钥文件，ca.crt为CA的证书文件，这两个文件后面的证书签名做准备
openssl req -days 3650 -nodes -new -x509 -keyout keys\ca.key -out keys\ca.crt -config openssl-1.0.2a.cnf
5.生成服务端证书
生成服务器证书请求文件和服务器私钥
openssl req -days 3650 -nodes -new -keyout keys\server.key -out keys\server.csr -config openssl-1.0.2a.cnf
CA签名
openssl ca -days 3650 -out keys\server.crt -in keys\server.csr -extensions server -config openssl-1.0.2a.cnf
清除.old文件防止将来创建文件出现错误
del /q keys\*.old
6.生成客户端证书
生成客户端证书请求文件和客户端私钥
openssl req -days 3650 -nodes -new -keyout keys\client.key -out keys\client.csr -config openssl-1.0.2a.cnf
CA签名
openssl ca -days 3650 -out keys\client.crt -in keys\client.csr -config openssl-1.0.2a.cnf
清除.old文件防止将来创建文件出现错误
del /q keys\*.old
生成的证书文件都在keys文件夹中
