Challenging yet fun course!

I learnt many new things.

Good introduction

very usefull

nice course

challenging

It was challenging and interesting. The only issue what I feel is that I am not from a coding background, so to understand the coding concepts were a bit tough. And I asked my queries through forums, but no reply came. But overall, it was an interesting course

Bravo! Oh man, the "RSA Quest" was the most amazing thing ever! I can't even believe it worked out. And ended with a nod to one of my favorite authors!

This course was one of the most challenging, and at the same time rewarding courses I've done on Coursera. I absolutely love learning from these instructors. Their explanations are so methodical and complete that you really get a good understanding of not only the facts they assert, but the "why" and "how" beneath it. Thank you!

Highly recommended. Initially, the course seems to be a bit slow-paced but later you will understand that it was all necessary to build the foundation. The material is very good especially the exercises. The last portion teaches you RSA encryption and its prospective attacks. Overall the course was very well structured and intuitive, it made me think and apply the concepts taught.

Alhamdulillah. Finally, I can pass this course, although not perfectly 100%, but I really proud of my self. Thanks to all lecturers in this course. I've got a lot of knowledge so far, especially in Number Theory. For cryptography subject, that's so hard. Not every people can solved it perfectly since it need a lot of creativity and logic.

My only critique to this course are the final two quizzes of week 4. The very final quiz relies on you having successfully completed most of the penultimate quiz and is more of a "copy and paste" session. The RSA part (week 4) of this course had not been covered at my University and was very interesting.

Alhamdulillah. I have learnt many things from this course. Thanks the three course instructor for taking this course. Most interesting things of the course for me was The end RSA Quest quiz. Again, Thanks coursera.

Excellent material and teachers.

Specifically, the course contents of week 4 : the RSA quiz and the RSA quest quiz material is outstanding! Kudos!

Excellent course to learn number theory principles and relate them to asymmetric cryptosystems. The course is highly rigorous and challenging.

This course was amazing! Got a good, but brief insight into the basics of cryptography. The examples at the end of the course were great!

Its a good course to the beginers of cryptography.If you want to join you should know basic number theory and computer language python.

This course introduces one into the world of cryptograghy and was very interesting especially the RSA Quest.

Very good course to learn the basic concepts of number theory and cryptography, and how to implement them.

I really appreciate the teachers' effort for the quests.

The most fascinating assignment ever.

Very challenging and exciting to. It was not math it seemed to be like more of puzzle games

A Very Good Course for Beginners who want to start learning cryptography from scratch

I can't really get sync b/w mathematics and programming

Very fun and simple, maybe too simple, but it's fine

Really good course, kept my really good questions

probably the best course of this specialization
