How To Install ssldump on CentOS 8
Introduction

What is ssldump
The ssldump program is an SSL/TLS network protocol analyzer. It identifies TCP connections on the chosen network interface and attempts to interpret them as SSL/TLS traffic. When ssldump identifies SSL/TLS traffic, ssldump decodes the records and displays them in a textual form to stdout. And if provided with the appropriate keying material, ssldump will also decrypt the connections and display the application data traffic. This program is based on tcpdump, a network monitoring and data acquisition tool.
