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.

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.

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.

I am now genuinely excited about cryptography. It is a huge field, but this is an excellent introduction. Having watching enough DefCon and Hak5, I know that a good number of 'professionals' in the industry are lacking the fundamentals. This course is the fundamentals. Dr. Katz is renown in the field, and obviously has a passion for the topic. I have also been re-inspired to 'make math my own.'

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.

A very informative and easily understandable course! I always fancied math, but never really got deep into it, so some of the primitives discussed here were new to me, but even so I was able to easily understand them thanks to Prof. Katz! And of course it was super exciting to find out in which way are modern secure connections secure. 10/10 would pass again.

I am very fond of the way the course material was presented. I found the definitions and proofs to be rigorous and intuitive at the same time, which is of great importance when learning such material. The accompanying textbook is great, too. Although I was already familiar with parts of the material, I thoroughly enjoyed the course.

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 :-)

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.

The professor is excellent. He covers a lot of subjects using good analogies without loosing depth. There are programming assignments to help you grasp the material.
