windows 下生成ssl证书

2023-09-01 958 0

1. 安装openssl

openssl官方没有提供windows下的安装文件,使用第三方软件下载地址
选择适合本机的版本下载,我下载的是 Win64 OpenSSL v3.1.2 Light 然后一直下一步安装即可

2. 配置环境变量

在环境变量path末尾添加 安装路径/bin
打开命令行输入 openssl help 检测是否安装成功 出现以下字符就算成功了

3.生成ssl证书

执行以下命令生成密钥 server.key,过程中会要求设置密码,按提示输入即可

openssl genrsa -des3 -out server.key 2048

输出:

Enter pass phrase for server.key:  ---> 输入密码
Verifying - Enter pass phrase for server.key:  ---> 验证密码

接下来执行以下命令去除刚刚设置的密码:

openssl rsa -in server.key -out server.key

使用密钥创建服务器证书的申请文件 server.csr,过程中会要求输入一些信息,不填也可

openssl req -new -key server.key -out server.csr

输出:

D:\Downloads\ssl>openssl req -new -key server.key -out server.csr
Enter pass phrase for server.key: ---> 输入上面设置的密码
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.

创建 CA 证书 ca.crt:

openssl req -new -x509 -key server.key -out ca.crt -days 3650

创建服务器证书 server.crt:

openssl x509 -req -days 3650 -in server.csr -CA ca.crt -CAkey server.key -CAcreateserial -out server.crt

生成后目前目录文件如下:
