Introduction

In the past decade, Data Security has become one of the biggest concerns for both small and large organizations. With more and more data breaches occurring every day, and legislators struggling to keep up with innovation, it is essential to protect sensitive data by all means necessary. Therefore, the first defense mechanism of every organization should be setting up proper network access and firewalls to prevent unauthorized access and secure all the endpoints.

However, security analysts should always work under the assumption that an attacker will find a way to break into a system. This is where encryption becomes crucial. Data encryption is a method by which one transforms data to make it ineligible by rewriting it in some code. Data encryption is not a new concept. We have been using various encryption techniques from ancient times to protect information from enemies in a data breach. However, encryption has come a long way in the past decade or two.
