如果你安装了Git，

您可以打开Git Bash (shift键+右键单击文件夹-> Git Bash Here)，并在Bash中使用openssl命令

检查openssl工具，这是一个来自LibreSSL项目和Cygwin库的openssl集合(2.5 MB)。NB !我们是包装商。

创建自签名证书的一行代码:

Openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout selfsigned。输出self - signed.crt

如果你已经安装了chocolatey，你可以通过一个命令来安装openssl。

choco install openssl

Necroposting，但可能对其他人有用:

There's always the official page ([OpenSSL.Wiki]: Binaries) which contains useful URLs (pointing to unofficial resources / builds, make sure to read the Important Disclaimer) There are other repositories which contain unofficial builds Here I want to mention: [GitHub]: CristiFati/Prebuilt-Binaries - Prebuilt-Binaries/OpenSSL v1.0.2u (FIPS capable) is built with OpenSSL-FIPS 2.0.16 Artefacts are .zips that should be unpacked in "C:\Program Files" (please take a look at the Readme.md file, and also at the one at the repository root) Other 3rd-party software may bundle OpenSSL, so it gets "installed" as a side effect. Such software (mentioned by other answers): Cygwin, Git And of course you can build it yourself from sources, but that requires some deeper knowledge

注意:当你有一个功能性的OpenSSL实例时(使用上面的任何方法)，下面是你如何从VStudio中使用它(如果你需要它到你自己的项目中):

我从https://slproweb.com/products/Win32OpenSSL.html安装了openssl 3.0.0。然后我进入windows start ->openssl->Win64 openssl命令提示符，它会打开一个像常规dos窗口一样的窗口，我所需要的就是进入openssl的安装文件夹。

如果您运行的是Windows 10 1709 (build 16299)或更高版本，则可以使用下面的winget命令安装OpenSSL

winget install -e --id ShiningLight.OpenSSL

或者如果你的系统上安装了Git for Windows，你也可以在Git文件目录中找到OpenSSL。

C:\Program Files\Git\usr\bin\openssl.exe
