This course offers a hands-on, case study-driven introduction to classical and modern cryptography using Python. Through a progression of real-world cipher implementations, learners will understand foundational encryption principles, apply cipher algorithms programmatically, and analyze vulnerabilities in both classical and modern encryption schemes.

Starting with basic reverse and Caesar ciphers, the course advances through brute force attacks, transposition techniques, and affine-based cryptography before culminating in public key cryptosystems like RSA. Learners will gain practical experience in building encryption and decryption tools, evaluating cryptographic strength, and creating secure systems using libraries like PyCrypto. By the end of the course, learners will be able to construct, experiment with, and critically evaluate cryptographic systems for secure communication using Python programming, while also demonstrating fluency in key cryptographic concepts such as hashing, key generation, and symmetric vs. asymmetric encryption.

This module introduces the fundamental concepts of cryptography and explains the importance of using Python as a tool to implement and explore basic cipher techniques. Learners will gain an understanding of how cryptography works and begin experimenting with simple encryption schemes.
