Very stimulating, very accurate, good balance between theory and practical examples. Many thanks to the teacher !!!

This is one the best course to learn Cryptography. This course is speacilly design for basic level to higher level.

One of the best introduction in Cryptography and Number Theory. Thanks to Author for clear explained information!

Excellent overview of Cryptographic concepts with a great range of interesting and challenging problems to solve.

This Course is TOP level: a must for anyone interested in cryptography, without any strong prerequisite knowledge

Pretty nice course! It helps me understand why encryption algorithms have been designed to be the way it is now.

Un cours excellent, capable de vous emmener des points de détails important. J'ai beaucoup aimé même si c'est un

Highly recommend this course for understanding the Basics of Crypto with the necessary Mathematical foundations

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.

E​xcellent class - not an easy subject, but the course is well-structured and well-taught. Highly recommended.

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.

In this course I've got much more cryptography knowledge than during my 15 years programming experience.

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!
