The explanations are clear and the topics are relevant, interesting, and well explained. I have a background in computing science and machine learning.

This is a fantastic course. It has greatly kindled my interest in cryptography, and I look forward to learning more on the subject from Prof Dan Boneh.

The topics were a bit difficult, but the teaching style made it easy to understand. Next time Please show us the programming section of cryptography.

Exceptional material covered by Prof. Dan Boneh! His lectures are a treasure and I am sure I will keep going back to them to refresh my foundations.

Was fast paced and very well designed course. Enjoyed all the aspects of the course and got to know many things regarding cryptography in practice.

Excellent Course. Requires lot of patience but the rewards are extremely great.

Learned a lot about internals mathematics involved in Cryptography.

Great introduction to cryptography. I have learned a lot from it, but still, there is much to study in this field. Surely I would come back again.

This course is brillant, with awesome (optional) coding problems to learn who to go from theory to practice! Thanks for these wonderful materials.

I think this course was an ecelent course. Too short and too many information. High-level teach by amazing Harvard professor. Thanks Dan Boneh.

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.

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.

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 :)

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.

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.
