Windows 安装 OpenSSL 生成自签名证书

Windows 安装 OpenSSL

https://slproweb.com/products/Win32OpenSSL.html

Win64 OpenSSL v3.1.2 Light
EXE | MSI

安装完毕，添加到系统变量 Path

C:\Program Files\OpenSSL-Win64\bin

win 键 + R，cmd，打开命令行界面

查看 openssl 版本

C:\Users\ran>openssl version
OpenSSL 3.0.5 5 Jul 2022 (Library: OpenSSL 3.0.5 5 Jul 2022)

比如想要生成的证书，放在 D 盘 cert 文件夹下，先 CD 到目录

C:\Users\ran>D:
D:\>cd D:\cert
D:\cert>

生成密钥，生成自签名证书

openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 3650 -subj "/C=CN/CN=ioufev.com" -out cert.crt

🍄 输出的密钥：key.pem
🍄 输出的证书：cert.crt
🍐 证明的信息：/C=CN/CN=ioufev.com

最简单的证明信息要有
💎 C=CN，表示中国
💎 CN=ioufev.com，证书绑定域名：ioufev.com

将密钥和证书合并成一个 pfx 文件，并输入文件保护密码：12345678

openssl pkcs12 -export -in cert.crt -inkey key.pem -out test.pfx -name test

🍄 输入的密钥：key.pem
🍄 输入的证书：cert.crt
🍏 输出的 pfx 证书：test.pfx
🍀 输出证书的名字：test，不加 -name test 的话，默认名字是 1

详细记录

C:\Users\ran>D:

D:\>cd D:\cert

D:\cert>openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 3650 -subj "/C=CN/CN=ioufev.com" -out cert.crt
