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

There is no reason why this course deserves anything less than 5 stars.

Everthying is nicely explained and there is so much to learn.

Teacher is very clear and the course contents are very good. This course is highly recommendable to any who is interested in crypto.

Fantastic course. I am getting preliminary idea of cryptography from this course. Hope to take the "Cryptography II" course as well.

Awesome course. Really tough math wise for me, having come into this straight out of high school. Made it though, and learnt heaps!

great course i learn a lot and let me know that i need to learn a lot more, thanks Dan and all the folks that answer on the forums

Best course for learning cryptography. Assignments questions are challenging and test every knowledge you learn during the course.

Amazing course full of useful content! Professor Dan Boneh presents complex cryptographic topics in a very understandable manner.
