Excellent course material with even more excellent Professor. thank you prof. for your generosity. thank you coursera for making this available.

Thank you very much for anyone that make this course very interactive and fun. Special thank's for Prof. Dan Boneh as Instructor in this course.

I really like the course. I dont understand the certificate polcies on coursera. Why do I have to both subscribe to coursera and to pay extra?

A bit hard for a person like me from third world at first but when you are into it, it become more clear. A great course. Yes, a great course.

So far, this is the most informative theoretical and mathematical course I’ve seen. It’s better suited for those who seek in-depth knowledge.

No matter whether you know what Cryptography is, and if you don't know whether you like it, you'll find the answer after taking this course.

An absolute gem of a course from Prof. Boneh. Uplifted me in so many different ways. I eagerly await the CS355 equivalent from Prof. Boneh.

My background is in mathematics, I found this course had very good explanations as well as a range of optional further reading / exercises.

This time it will be finished. I have such a craze on cryptography and network security. i want to finish the course perfectly this time :)

Very good approach to introduce the student in the cryptography world.

Tank you Dan Boneh!

Thank you Coursera!

Thank you Stanford University!

Amazing content, great structure, easy examples even for first-timers, and a handful of extra-reading resources. Recommended for everyone.

This course is filled with a great amount of information covered at a fast pace. A must do course if you need to get into Cyber Security.

Good pace , reading along the transcribed speeches of the professor.The professor broke down the lesson into easily understandable bits.

This is really awesome for basic learners of cryptography. This course motivated me to choose Cybersecurity field for my future studies.

Course was fun and very interesting, particularly the programming assignments. Beware, some of the math topics were fairly challenging!

Thank you for creating this course and enabling anyone with a smartphone and an internet connection to learn this powerful technology.

Very interesting. A little fast paced. As suggested, we should pause, think, and then continue, in order to get most out of the course.

Many thanks to Dan Boneh and everyone involved in preparing this amazing course!

I can't wait for Cryptography 2 (hopefully this fall?).

Excellent course. Dan explains crypto from the ground up making it easy to understand more advanced constructions as the weeks advance.

Very informative and convinient course, everything is pretty easy to understand thanks to Stanford University, Coursera and Dan Boneh!

Awesome, good explanations, pretty hard on the math area (for me) but once you understand the way Dan explains it it's easy to follow.

O Curso é ótimo, está me ajudando bastante, faço o download dos videos e do material e estudo em casa e me preparo para as avaliações!

This was a very helpful introductory course I would recommend to anyone with no experience. Lectures were clear and easily understood.

Very good course for anyone with some programming background. An pre-requisite understanding of modular arithmetic would be helpful.

An amazing course. As a person who deals directly with cryptography i see myself with a huge knowledge improvement doing this course
