Install and Configure OpenSSL on Windows Server 2019

In this article, we want to teach you to Install and Configure OpenSSL on Windows Server 2019.

OpenSSL is an all-around cryptography library that offers open-source applications of the TLS protocol. It is available for Linux, Windows, macOS, and BSD systems. OpenSSL allows users to perform various SSL-related tasks, including CSR (Certificate Signing Request) and private keys generation and SSL certificate installation.

Install and Configure OpenSSL on Windows Server 2019

To install OpenSSL on your Windows Server, you can follow the steps below.

This guide will cover the installation of OpenSSL on Windows Server 2019, 2016, 2012.

Installing OpenSSL on Windows Server 2019

First, you need to visit the OpenSSL Downloads Page and take the latest version of OpenSSL that matches your CPU architecture. You have an option of choosing the Light version or the full version.

Here we will download the 64-bit version.

Also, you can use the curl.exe command to download it from the PowerShell:

curl.exe -L -o Win64OpenSSL.exe  https://slproweb.com/download/Win64OpenSSL-3_0_1.exe
PS C:\Users\Administrator> curl.exe -L -o Win64OpenSSL.exe https://slproweb.com/download/Win64OpenSSL-3_0_1.exe
Output

When your installation is completed, run the installer by double-clicking on .exe file or from PowerShell run the command below:

.\Win64OpenSSL.exe

Then, accept the Software license agreement and click “Next”.

Configuring OpenSSL on Windows Server 2019

At this point, you need to add C:\OpenSSL-Win64 to the Windows environment PATH. From your PowerShell run the command below:

$userenv = [System.Environment]::GetEnvironmentVariable("Path", "User")
[System.Environment]::SetEnvironmentVariable("PATH", $userenv + "C:\OpenSSL-Win64\bin", "User")

Note: For a 32-bit system, replace OpenSSL-Win64 with OpenSSL-Win32.

Now you are ready to use OpenSSL on Windows Server 2019 to generate certificates. Start by exporting OPENSSL_CONF.

set OPENSSL_CONF=C:\OpenSSL-Win64\bin\openssl.cfg

Then, create a test SSL certificate to validate our installation.

openssl.exe req -new -nodes -keyout server.key -out server.csr -newkey rsa:2048
PS C:\Program Files\OpenSSL-Win64\bin> ls

Directory: C:\Program Files\OpenSSL-Win64\bin
