Very interesting course. I would like programming assignments to be mandatory, not optional. Or at least there should be a way to get some information that the assignment is passed on Coursera page.

Wonderful and well organized course, it is really recommended to take it for those who are interested, which will definitely provide you with really understanding of cryptography!

Could be because I studied electrical engineering I'm missing some needed mathematical background, but the way the content is explained in this course I often needed to look into other sources that explained it in a more understandable way for me. Hence I needed much more time than expected for this course and I have the feeling it's possible to explain a lot of parts in a more understandable way if there would be more notes and explanations to the formal definitions.

I enjoyed the lextures. They covered a lot of material in very short time.

But i am deeply dissappointed of lack of examples, test exercises and disactive forum. If you dont get something right a way or you have any doubts, then you are sadly alone, because no-one is reading or giving correct answers on the forum;

Interesting review of all crypto basics, maths. It is an starting point, the first gate, then you may go deeper and discover more details and applications.

It was mostly theory . Wished for understanding about tools , etc. and see and perform some real things. I don't know , I expected a tad more.

Very dull. Every time I try to watch a video, I find myself having a nap. Go for Cryptography I instead.

I think this course is mostly useless. For people outside academia it's way too much in the weeds of formal proofs and mathematical constructs to give any practical knowledge to use in software engineering. On the other hand someone already in academia and studying mathematics and cryptography would probably already know this stuff. So I don't know what the target audience for this course is, but I know it's not me.

This course is hard to follow. Not much explanation or readable materials are provided just formulas that are unusable. As a mathematics student and a big fan of probability, I think each module need to be more polished and straight-forward to understand rather than just pouring formulas.

I find it very hard to follow and think I should be using the time to go over another course.

The lessons were too long, it is very hard to stay focus on these videos.

This is a good course for deciding if you want to pursue a more advanced degree in Cryptography, Computer Science, or Mathematics, but As part of a Cyber Security specialization, your paying customers are most likely working professional engineers or programmers, interested in practical applications of cryptography that they can use in order to create secure systems and services. This is a mathematics course and your paying customers are not going to use the knowledge from this course in their jobs. This is not an indictment of the instructor, but of the content itself. It is the wrong content for your target customer.
