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):

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

你可以从这里获取https://slproweb.com/products/Win32OpenSSL.html

得到https://wiki.openssl.org/index.php/Binaries的支持和认可

你安装Git了吗? 您可以在Git Bash中访问openssl命令，而无需添加任何环境变量。

但是，如果你想从Windows cmd中访问openssl命令，请跟随我:

找到Git bin目录的路径。通常是在

C:\Program Files\Git\usr\bin\

然后添加路径你的环境变量(User变量-> path):

现在打开一个新的命令提示符(不要使用已经打开的cmd，因为已经打开的cmd不知道新的环境变量)。

现在写:

openssl

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。
