This course is a beginners guide to cryptography and imparts to the beginner a basic understanding of the science. We cover the terminology, process and mechanics of cryptography and as well as how to put the understanding together with a view to protecting data, an important understanding for those who deal with sensitive corporate/customer information.

This course covers the use of cryptographic systems with knowledge of the basic concepts involved, but  without needing deep technical knowledge of the subject.

Learning Objectives
  • Recognize the need for cryptography
  • Identify the primitives of various cryptographic techniques and the related application areas.
  • Explore the various types of cryptography and the associated application areas

Cryptography is the practice of securing communication and data by converting it into a form that is unintelligible to unauthorized individuals. It involves the use of mathematical algorithms to transform plaintext (original data) into ciphertext (encrypted data).

very interesting course covering a host of information on encryption, history, importance of privacy of information. It gives a great foundation on the subject matter and some disadvantages and advantages of different methods of encryption.

Good for a really early beginner. Would love a more advanced course that actually delves into the contemporary technologies with relevant cases/examples.

I liked the material. For an hour the depth of the material was sufficient. Perhaps Illumeo could offer a course with more detail if there isn't one.

This course is more of a history class. The slides are from 2014 and some of the comments don't address issues which have come up sine 2019

I think many things have changed around security since the original slides were created. Maybe it's time for an update.
