Ensuring your OpenSSL version is up-to-date is crucial for maintaining system security and functionality. Whether you’re a developer or a system administrator, knowing how to quickly check your OpenSSL version can save you a lot of headaches. Here’s a quick guide to help you effortlessly check your OpenSSL version.

How do I check the version of OpenSSL?

1. Using the openssl version command

You will see the OpenSSL version number and the date of its release. This command is straightforward and gives you the necessary details immediately. It also works the same in PowerShell if you prefer it.

This solution is the quickest way to check your OpenSSL version and is useful for ensuring that your software is up-to-date or for troubleshooting.

2. Checking via Package Manager (Linux)

This will list all installed versions of OpenSSL managed by your package manager. This solution helps you understand which versions are available in your distribution’s repository and which one you have installed.

3. Using the strings command on Libraries (Linux)

This will output the version of the OpenSSL library directly from the binary. This solution is useful if you have multiple OpenSSL installations or need to verify the OpenSSL version bundled with an application.

4. Programmatic check in C++

This program will print the OpenSSL version used in your C++ application. This solution helps developers programmatically check the OpenSSL version used in their applications, which is particularly useful during development and debugging.

By following these solutions, you can easily check the OpenSSL version on various systems and contexts. Regularly checking your OpenSSL version helps ensure your system’s security and functionality. Always keep your software updated to protect against vulnerabilities.
