Extremely detailed course. Some computer and/or math knowledge is necessary for this course. Otherwise most of it will fly over your head. It covers the essentials of cryptography and touches on practical use as well. Definitely recommended.

The lectures are clear and well made. The assignments, especially the optional programming assignments are interesting and helpful for understanding the theory learned in the lectures and seeing some ways they can be applied. Awesome course.

Excellent course! I can recommend this to anyone who is not afraid of some basic math. But a person interested in cryptography should not be afraid of math, yielding that this course can be recommended to anyone interested in cryptography.

This course is a little difficult compared to any other courses i have taken in coursera. Very vast, problematic but fun to learn and Try to complete coding assignments, they are help in understanding the encryption techniques very well.

Exceptional material for anyone wanting to add Cryptography to their toolbox. Previous maths knowledge doesn't hurt. And some basic coding knowledge, if you wish to engage with the additional material.

I eagerly await v.2 of this course!

Challenging, yet very informative. Dr. Boneh is extremely good at explaining the concepts of basic Cryptography. I especially liked the "proofs by images". Will be definitely going for Crypto 2 as soon as I have time available for it.

When someone explains concepts and ideas in such an easy way, it means he/she understands fully what he talks about; this is the case of Professor Dan Boneh; I widely recommend this course for anyone interested in Cryptography topics.

One of the best courses of my life, well planned, very up to date, with good examples, good academic level. Very recommendable for those who want to know the new discipline created in the term of the last century called cryptography.

Well organized course with excellent problem sets and exams. Covers basic crytoanalysis, MAC, symmetric cipher, key exchange and asymmetric encryption. Great introduction to the topic with a relatively low level of mathematics.

Without any hesitation, one of the best computer science courses I've ever had. Dan is brilliant, straight to the point and very pedagogue. Thank you for this wonderful course, and looking forward to studying Cryptology II soon :)

Amazing course. Learnt a lot regarding crypto basics and concepts behind it. The math was a bit tough at some points but the explanations were excellent so that there is little to no doubts left at the end. Can't wait for Crypto 2

I learned a lot from this course. From my perspective (background in math), Boneh made a good trade-off between a rigorous approach and covering real-world crypto - both is covered to a sensible degree. Looking forward to part 2.

Great course.

The material is explained masterfully. The exercises are interesting, challenging and effectively strengthen the knowledge acquired from the lectures. One of the best courses I've taken both in university and online.

Dan Boneh is an excellent instructor - as you start wondering some questions during his lectures, the next minute he would answer it in the video. Some sections might be a bit too maths-heavy for those with no maths background.

This is the best course in cryptography.

Yes, it is difficult, but this course is necessary to understand the topic and grow knowledge in this industry.

Thanks to Dan Boneh for his great work and inspirit example for students.

Incredibly well explained- I learnt so much from a base of little knowledge and the format was really good. Weeks 7 and onwards are mentioned to be in a different course so I'll have to find that as well. Thank you very much!

It 's the second time I follow this course and I still find that so amazing. I'm waiting Crypto II until a year and I hope it will be released soon... Thanks Pr Boneh for sharing your little (for you) big (for me) knowledge !

Really cool course that was fun and very informative. Really well designed quizzes, homeworks, and programming assignments. It was pretty difficult compared to most online courses but I guess that's expected from Stanford...

Time consuming and hard work but very rewarding. Took me several attempts to finish (other life commitments kept getting in the way).

Will be doing it at least once more to try and finish all the programming exercises too :)

This Is AWESOMEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The extra assignments where the best! The lectures explain in a way it is easy to understand. And still the course holds a reasonable amount of mathematics and examples making the course a little more complex and deep.

Can be difficult at times but the concepts are definitely rewarding. The psets were creative and effectively asked students to apply concepts. Dan Boneh is articulate as always and knows how to get the subject across.

I started this course a long time ago, it feels great to finish it. There was a lot of theory, but the message of 'don't try it build it yourself' was driven home. I look forward to the other topics in cryptography 2.

I had not taken any cryptography classes before taking this class. Professor Boneh did a great job explaining the concepts, and I feel like I have a much better understanding of cryptography now. Excellent course!

This was a much more in depth and theory-based approach to cryptography than others I've taken. It was super valuable, even having prior experience working with many crypo primitives and protocol implementations.
