Welcome to Cryptography and Key Exchange, a Udemy course that will take you on a journey through the world of modern cryptography. In this course, you will learn how to implement and break some of the most fundamental cryptographic protocols, including Diffie-Hellman key exchange, Secure Remote Password (SRP), and RSA encryption.
Through a series of hands-on programming challenges, you will gain a deep understanding of how these protocols work and how they can be attacked. You will learn how to implement them in code using a programming language like Python, and how to detect and defend against common cryptographic attacks like man-in-the-middle (MITM) attacks, dictionary attacks, and broadcast attacks.
Here's what you'll learn in this course:
The principles of key exchange and how the Diffie-Hellman protocol works
How to implement Diffie-Hellman key exchange in Python
How to perform a MITM attack on Diffie-Hellman and how to defend against it
How to negotiate group parameters for the Diffie-Hellman protocol and how to detect and defend against attacks using malicious "g" parameters
The principles of password-authenticated key agreement (PAKE) protocols and how the Secure Remote Password (SRP) protocol works
How to implement the SRP protocol in Python
How to exploit vulnerabilities in the SRP protocol, including attacks using zero keys and dictionary attacks
The principles of RSA encryption and how the RSA algorithm works
How to implement RSA encryption in Python
How to perform a broadcast attack on RSA ciphertexts with small public exponents and how to defend against it
By the end of this course, you will have a solid understanding of the principles of modern cryptography and key exchange, and you will have gained practical experience in implementing and breaking some of the most fundamental cryptographic protocols.
