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):

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

我还想为Windows 10创建OPEN SSL。有一种简单的方法可以避免从第三方网站安装未知软件和冒病毒的风险，就是使用Git for Windows安装中的openssl.exe。在我的例子中，我在Git for Windows安装的下面位置找到了开放SSL。

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

如果您还想了解如何使用OPENSSL生成和使用证书，这里是我博客上的一篇文章。分步说明首先解释了如何使用Microsoft Windows默认工具和OPEN SSL，并解释了它们之间的区别。

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

将Git中的openssl设置为默认的openssl，并将其包含到环境变量的路径中(快速方法)

OR

从这里安装系统特定的openssl 链接。 设置如下变量:Set . Set OPENSSL_CONF = LOCATION_OF_SSL_INSTALL \ bin \ openssl.cfg 更新路径:set path =…其他值 在这里……;LOCATION_OF_SSL_INSTALL \ bin

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。
