Overview What You Will Learn Curriculum Instructor

Course Overview

Attacks on organizations have been growing rapidly in recent years, with high-profile breaches being disclosed in all sectors of business, potentially leading to the theft of private information, financial losses, hefty fines, and reputational damage for the organizations that fall victim to them. The outlook on these attacks and breaches has slowly shifted from being an "if" scenario to a "when" scenario, as it is nearly impossible to cover every vulnerability, especially with new vulnerabilities being discovered by attackers every day.

A strong cybersecurity posture requires a combination of multiple domains, with cryptography being one of the most critical - yet often overlooked or underused - of the bunch. Cryptography can be used preventatively, but it can also be used to secure your data even if a breach occurs and the data is exfiltrated. This course will cover in depth the two main branches of cryptography - symmetric and asymmetric, as well as hashing and steganography, and how to implement these using free libraries available in Python. Live coding exercises that you can follow along with will show you exactly how you can accomplish this, and all of this will be accompanied by in-depth explanations for you to fully understand the topic at hand.

This course is focused on helping you fully appreciate the need for robust cryptographic security and the best practices and standards to meet the goal of securing your applications and protecting your user’s private information.

Christopher OMarra

Christopher O'Marra has experience in both the private and public sectors at some of the largest organizations in Canada as a certificate and key management strategist which involves planning, building, and deploying both certificate lifecycle management (CLM) solutions and public key infrastructures (PKIs), as well as configuring, maintaining and managing hardware security modules (HSMs) for key management. He has also developed in Python and other programming and scripting languages for many years automating processes, developing desktop and mobile applications, and at one point developing machine learning algorithms for small to medium-sized organizations. He knows that cryptography can at first appear as an overwhelming and complex topic but takes joy in being able to break it down in an engaging way so that others such as yourself can understand and grasp the topics being discussed. Chris is fascinated by all things cryptography and wants to share his knowledge in a rapidly growing domain so that others can benefit from it, and so they can be prepared for the future in a post-quantum world.
