Widows下利用OpenSSL生成证书

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

# For use with easy-rsa version 2.0 and OpenSSL 1.0.0*

# This definition stops the following lines choking if HOME isn‘t

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的证书请求文件,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
