This course is excellent, it fullfills what is promised in the course intro through crystal clear explanations.

great introduction to crypto.

Enjoyable and well designed course. Challenging material and practical exercises.

Very very interesting topic. I like this course so much. It is the key to the information security. Thank you.

Stanford's MOOCs are the best! They are hard but always worth the effort. And can't wait for Cryptography II.

I have greatly enjoyed the course though learning has been slow for me as I have been out of touch too long.

Very hard course although explained very well, takes a lot of time to understand every concept but worth it.

Great course, some difficulty reading notation, I would make the questions a bit more verbose in the tests

Thank you very much for this amazing course, my priorities in software has been changed after this course.

Pretty informative course! Material was well presented and seemed up-to-date. Looking forward to Crypto 2!

Excellent courseware and delivery! I highly recommend digital security professionals to take this course.

Gives a very good comprehensive view of cryptography. One regret: should have included digital signatures

Excellent course, i recommend it to any one willing to start understanding and working with cryptography.

Really helps to understand the underlying concepts of SSl and hence helps understand the working of SSL.

I feel pretty pleasure for finishing this course. The teacher is patient and knowledgeable, I like him!

A broad, fundamental dive into private and public key encryption systems. Challenging and informative!

Great course. Arguments are explained quickly but clear. Very good the quality of lectures and slides.

Challenging Interesting Course. Really goes thought very basic concepts to build everything bottom up!

The schedule was very tough. There were a lot of tests in the end of each module. But it was worth it.

I did a lot of crypto back at the university. This is a great opportunity for a thorough refreshment.

Excellent material to learn what "security" means, and what algorithms have been built to improve it.

it is a great course, covers a lots of different area with details and concepts. i like it very much.

Very thorough course and engaged presentation. Thanks for providing, and waiting for the sequel ...

Excellent introduction to crypto primitives with gentle coverage of formal definitions and methods.

This was an excellent introduction to a topic that is difficult to understand at the detail level.

Complete introduction to basic aspects of cryptography along with required pre-requisite of maths.
