These courses applied cryptography courses are poorly organized, contain inconsistent terminology, have mistakes and badly worded questions in the quizzes, fail to explain concepts adequately, and generally disappoint at all levels. Plus there is zero support on the discussion forums. I would not recommend.

It was a bit too easy. I did not find the content precise (let alone formalized), it also was not preparing for real world applications

Entire course (supposed to be ~4 weeks) amounted to the amount of information you'd get in one college lecture session

its a very good course for the starting in the Security field.

The course is too short

There is little to take away from this course other than the Information Entropy formula. The questions are poorly formatted (one of them asked to evaluate "the following true false statement" and the statement had no true false evaluation). The questions in the quizzes appear to have been given little though, and are primarily computation, or true false. There is little to actually unpack, and to even attempt to understand. The lecture styles aren't organized, or informative. The instructor either doesn't present enough, or presents too much, on a given topic, and when writing they often try to cram EVERYTHING at the end, rather than starting a new slide. I'd have apprecaited it more if, instead of cramming their handwriting, when they attempted to summarize a topic, like information entropy, that they'd switch to a slide that was neatly typed or written, which clearly expresses what they'd hope for us to take away from that series of slides.

Very poor and waste of money and time
