Interesting course on an Interesting topic taken in a pleasant, enjoyable, and simple manner.\n\nNever did I feel bored or out of my depth even though I am a stranger to the topic.

The Course was hard to grasp, Sometimes felt certain things were unclear like while explaining the theory that has numbers please add it on the screen. But It was one of the most educational and helpful courses on cryptography.

This course makes me know more about the history of cryptography and some other attacks precisely.

Personally, I found this course to be pretty anti-didactic. First, it is listed as a beginner course, but some of the probability concepts aren't explained directly in the course. Another observation is that almost all of the aditional readings provided are from Wikipedia - I get that many courses need to have a self-taught part for the student to better comprehend the concepts or get a deeper understanding, but had I wanted to read only Wikipedia articles I could've done that without enrolling to this course. Lastly, I think it lacks exercises to put the knowledge into practice. However, it did gave a quick review of many basic concepts and serves as an introduction to the field.

Nice and easy undergraduate course, but not useful for students seeking for a big picture of state-of-the-art cryptography. Content of this course is way too old.
Encryption/decryption of English characters are dinosaur technologies for telegraph, which itself has disappeared in modern communications.
Too many historical tales, too few modern technologies, and almost no technical details or math.
BTW, there are quite a few mistakes in slides, and the instructors don't response questions on discussion forums.
I don't believe students should start from the ancient age to learn modern cryptography, not very useful course in general.

I think this is the worst course in Coursera which I have taken. The lecture is very bad , only see the teacher saying from begining to the end, without prepare any animation and slides. I can not remember so much usefull knowledge about the Cryptosystem in the course, I should self learning a lot of things from the link after each course. The professor did not give me any more value but only some link from wikipedia.
