Excellent course. The proofs that are laid out in a way that made it easy for me to follow along, and it gave me a good overview of the areas of cryptography that are most relevant to me.

Prof. Katz is an excellent teacher and has created excellent material for the course. He explains every lesson in the course in great detail and the quizzes are sufficiently challenging to validate what you've learnt from the lesson.

It is good but I have to do extensive research of what is being thought and I have to study your book like Introduction to Modern Cryptography and attend other Cryptography online courses, only them I am able to understand this course. If more examples and solved problems will be provided then it will be very helpful. Samples programs are very good and able to solve. Thank you.

I started loving Coursera since "Machine learning" by Andrew Ng and what amazed me most was his ability to explain complex mathematical concepts in really simple words, with clean, readable hand-drawn diagrams and drawings. I'm really missing this in the Cryptography course. This course is quite difficult to understand and follow. Even if you have background in probability, the lectures explain a little of the underlying concepts and most of the lecture is essentially reading formulas and definitions from the slides. Even the presentation is unreadable - the formulas on slides aren't actual mathematical formulas but formula-like text typed in PowerPoint without any mathematical symbols or typography (lower or upper indexes, fractions etc). For example, the Bayes law is presented in the course as rather cryptic string "Pr[A|B]=Pr[B|A]*Pr[A]/Pr[B]" and here's its original, clean and readable formula for comparison https://goo.gl/P8Cvu2 This gets even worse when it's being substituted into a multi-line equations, which - guess what - are simple PowerPoint text either.

I felt it was a good introduction to cryptography. There were quizzes and programming assignments throughout the course to assess knowledge.

Very useful insight about Cryptography, very good practical assignments. I advise it to everyone interested in Cyber Security. Very stimulating.

An enjoyable trip through the history of crypto schemes, and practical attacks against them. By the end of this class you will have a good basic understanding of modern cryptography and real world implementations used online everyday. It's designed in a balanced way so that both those with a Mathematics background and those with programming backgrounds can both keep up.

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.

Cryptography is one of the areas that most developers know just enough of to be really dangerous. Reverse-engineering and debugging code I have seen way to many examples to list here of home-baked attempts at cryptography.

Lots of notational math but a great course to get into the meat of cryptography and understand the foundation of this most important topic.

Underneath that Professor facade, I suspect he's a wild and crazy guy :-)
