Digital Defenders CTF 2023 Masterclass Webinar-8

Samgacchadhwam Series Webinar #64

Topic: Cryptography - Part 2
Speaker: Mr. Pagilla Manohar Reddy, Amrita Vishwa Vidyapeetham
Date: Friday, 30th June 2023
Time: 3:30 - 5:00 p.m.

During this webinar, we will dive deeper into advanced encryption techniques. Join us as we explore RSA, Modular Arithmetic, AES, and Block ciphers.

During the first part of the webinar, we will unravel the mysteries of RSA and Modular Arithmetic. We will begin by introducing the concept of Modular Arithmetic and its relevance in encryption algorithms. Next, we will delve into RSA, a widely used asymmetric encryption algorithm. You will gain a comprehensive understanding of how RSA works and its key components. To reinforce your knowledge, we will engage in a hands-on RSA key generation exercise, allowing you to generate your own RSA keys. Moreover, we will explore the vulnerabilities of weak RSA implementations through a breaking weak RSA exercise. Through live demonstrations, we will also showcase the process of cracking old RSA certificates, highlighting the importance of robust encryption practices.

In the second part of the webinar, we will shift our focus to AES and Block ciphers. We will present real-world examples of AES implementation, shedding light on its significance in modern cryptography. Delving into the inner workings of AES, we will explore its encryption and decryption processes, with a specific focus on the ECB mode. Furthermore, we will provide you with simple exercises to familiarize yourself with AES and its application.

By the end of this webinar, you will have a solid understanding of advanced encryption techniques, including RSA, Modular Arithmetic, AES, and Block ciphers. You will gain practical experience through hands-on exercises and live demonstrations, equipping you with the knowledge to implement robust encryption practices and safeguard sensitive information.
