How to upgrade OpenSSL on Centos 7 or RHEL 7

1. Introduction

OpenSSL is a library that provides cryptographic functionality, specifically SSL/TLS for popular applications such as secure web servers, MySQl databases and email applications. The list parameters standard-commands, digest-commands, and cipher-commands output a list (one entry per line) of the names of all standard commands, message digest commands, or cipher commands, respectively, that are available in the present openssl utility.

2. Requirements

You may need an operating system RHEL 7 or Centos 7 in your dedicated or vps server. Please make sure to set a hostname for your server and its dns is pointing to the IP address of the server.

3. Installation

Get the current version with “openssl version” and “yum info openssl” command :

# openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013

You can also check the available version in the vendors directory too.

# yum info openssl
