To Install And Update OpenSSL On Linuxmint 18.3

OpenSSL is an open-source implementation of the SSL and TLS protocols. It is so simple to install and update OpenSSL on an Ubuntu machine, and this tutorial deals with the same.

Installation

Before starting the installation of OpenSSL, get the current version of OpenSSL by using the following command.

linuxhelp ~ # openssl version
OpenSSL 1.0.2g  1 Mar 2016

After that, download the latest version of OpenSSL by deploying the following command.

linuxhelp ~ # wget https://www.openssl.org/source/openssl-1.0.2-latest.tar.gz

Lets move it to /usr/src directory

linuxhelp ~ # mv openssl-1.0.2-latest.tar.gz  /usr/src/
linuxhelp ~ # cd /usr/src/
linuxhelp src # ls
linux-headers-4.10.0-38  linux-headers-4.10.0-38-generic  ndiswrapper-1.60  openssl-1.0.2-latest.tar.gz

Once it is downloaded, extract the downloaded OpenSSL tar file as follows.

linuxhelp src # tar xzf openssl-1.0.2-latest.tar.gz 
linuxhelp src # cd openssl-1.0.2o/

To manually compile OpenSSL and install/upgrade OpenSSL, make use of the following command.

linuxhelp openssl-1.0.2o # ./config

Let' s check the version now.

linuxhelp openssl-1.0.2o # openssl version
OpenSSL 1.0.2g  1 Mar 2016

If the old version is still displayed or installed before, please make a copy of OpenSSL bin file.

linuxhelp openssl-1.0.2o # mv /usr/bin/openssl /root/
linuxhelp openssl-1.0.2o # ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl

Now verify the OpenSSL version.

linuxhelp openssl-1.0.2o # openssl version
OpenSSL 1.0.2o  27 Mar 2018

With this, the method to Install And Update OpenSSL On Linuxmint 18.3 comes to an end.
