There are 5 modules in this course
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.
What's included
6 videos3 assignments
This module explores brute force attacks and introduces transposition ciphers. Learners will understand the mechanisms behind these techniques, implement encryption and decryption programs, and analyze cipher weaknesses through automated English detection.
What's included
6 videos3 assignments
This module delves into classical encryption methods including the multiplicative and affine ciphers. Learners will build modular arithmetic utilities, encrypt and decrypt messages, and evaluate cryptographic strength based on key structure and inverses.
What's included
6 videos3 assignments
This module focuses on more complex symmetric encryption techniques such as substitution, Vernam (one-time pad), and Vigenère ciphers. Learners will implement and test these ciphers, and understand their cryptographic strength and vulnerabilities.
What's included
9 videos3 assignments
This module transitions to modern cryptographic techniques including Base64 encoding, hashing algorithms, and public-key cryptography using RSA. Learners will implement secure communication protocols, work with key generation, and understand the mathematics behind prime factorization and encryption algorithms.

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
