Python Case Study - Cryptography

О курсе

Discover how cryptographic systems work by implementing and analyzing them with Python through practical case studies. This course introduces both classical and modern cryptography, helping you build a strong foundation in encryption techniques while exploring how secure communication systems are designed and evaluated. You will begin with core cryptography concepts and simple ciphers such as reverse and Caesar ciphers before progressing to brute force attacks, transposition, multiplicative, affine, substitution, Vernam, and Vigenère ciphers. As you advance, you will implement encryption and decryption programs, analyze cipher vulnerabilities, and evaluate cryptographic strength using Python. The course concludes with modern cryptography topics, including encoding, hashing, cryptographic libraries, and RSA public-key cryptography, where you will construct and validate RSA key pairs using modular arithmetic. Designed for learners interested in Python programming and cryptography, this course emphasizes hands-on implementation and analysis through real-world case studies. By the end of the course, you will be able to build encryption and decryption tools, compare classical and modern cryptographic techniques, analyze cryptographic weaknesses, and implement secure communication methods using Python.
