How To Install openssl on Rocky Linux 8

In this tutorial we learn how to install openssl on Rocky Linux 8. openssl is Utilities from the general purpose cryptography library with TLS implementation

Introduction

In this tutorial we learn how to install openssl on Rocky Linux 8.

What is `openssl`

The OpenSSL toolkit provides support for secure communications between machines. OpenSSL includes a certificate management tool and shared libraries which provide various cryptographic algorithms and protocols.

We can use yum or dnf to install openssl on Rocky Linux 8. In this tutorial we discuss both methods but you only need to choose one of method to install openssl.

Install openssl on Rocky Linux 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

After updating yum database, We can install openssl using dnf by running the following command:

sudo dnf -y install openssl

Install openssl on Rocky Linux 8 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

After updating yum database, We can install openssl using yum by running the following command:

sudo yum -y install openssl

How To Uninstall openssl on Rocky Linux 8
