Configure OpenSSL Environment Variables

To set up the environment variables for OpenSSL, you need to follow these steps:

1. Download and install OpenSSL.
   Download the OpenSSL installer for your operating system and follow the installation guide for guidance on installation.
2. Locate the installation path of OpenSSL. During the installation process, you can choose to install OpenSSL in a specific directory or use the default installation path. Remember this path as you will need it for the following steps.
3. Open the system’s environment variable settings.
   On Windows systems, you can press the Windows key + R key, then type “sysdm.cpl” and press Enter to open the System Properties dialog box. In the dialog box, select the “Advanced” tab, then click the “Environment Variables” button.
   On Linux or Mac systems, you can open the terminal and type “vi ~/.bash_profile” to edit the bash configuration file.
4. Add the path of OpenSSL to the environment variable.

   Add the installation path of OpenSSL to the “Path” variable in either the system environment variable or the user environment variable. In a Windows system, you can add the installation path of OpenSSL to the value of the “Path” variable, separating multiple paths with semicolons. In Linux or Mac systems, you can add the following line to the bash configuration file:
   export PATH=/path/to/openssl:$PATH
   Where /path/to/openssl is the path where you have installed OpenSSL.

5. Save and close the environment variable settings.
   On a Windows system, click the “OK” button to save and close the System Properties dialog box. In Linux or Mac systems, you can press the Esc key, then type “:wq” to save and exit the vi editor.
6. Reboot the terminal or command prompt window.
   To ensure that changes to the environment variables take effect, you will need to reboot the terminal or command prompt window.

Now that you have completed the configuration of the OpenSSL environment variables, you can use OpenSSL commands in the terminal or command prompt window. For example, typing the “openssl” command in the terminal or command prompt window should display the version information of OpenSSL if the configuration was successful.
