OpenSSL is an open source toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols, as well as an encryption library, so it is vital to keep it currently updated.

To verify the installation and version of OpenSSL, you can run the following command:

openssl version -a

In the event that OpenSSL is not updated to the latest version available

Execute the following command:

sudo apt-get install openssl

Note: If the result line is 0 updated packages, there are no updates available for the OpenSSL package.
