How to check OpenSSL version?

OpenSSL is an open-source software library and toolkit that implements the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is widely used to secure communications over computer networks, including the Internet. OpenSSL provides cryptographic functions and utilities, making it essential for tasks such as securing web servers, encrypting data, generating certificates, and verifying digital signatures. Many web servers, applications, and operating systems incorporate OpenSSL for its encryption and security capabilities. It plays a critical role in ensuring the confidentiality and integrity of data transmitted over network connections.

To check the version of OpenSSL installed on your system, you can use the following command in the terminal or command prompt:

Here are the steps:

1. Open Terminal (Linux/macOS) or Command Prompt (Windows): Depending on your operating system, open the terminal or command prompt.
2. Run the Command: In the terminal or command prompt, type and execute the following command:

3. View OpenSSL Version: The command will display the OpenSSL version installed on your system, along with the release date.

The output might look like:

This will indicate the OpenSSL version currently installed on your system.

You can find more information about OpenSSL on the official OpenSSL website (https://www.openssl.org). The OpenSSL website provides extensive documentation, user guides, tutorials, and links to resources for learning and using OpenSSL for various cryptographic and security tasks. Additionally, you can explore OpenSSL-related topics in online forums, security communities, and programming or cybersecurity websites to gain a deeper understanding of its capabilities and applications.
