The content in the lectures is pretty good. I would've liked some better reading materials beyond Wikipedia, and the presenter was hard to listen to as a lecturer because he seemed to be just reading from a cue card. I learned stuff though.

It is a good course. I got few information about hash attack which I didn't know before. Only thing which I wish to have more is a little more hands on and also detailed example about Vigenere cipher

Introductional but very nice. Grading can maybe be bettered. Seems somehow to investigate if you have "followed" than if you have "understood" but not easy to do much better for an online course.

Great course!

But please add the translation into Russian. It is very difficult to understand technical English from a topic of cryptography that is unfamiliar to me, as a beginner.

I was expecting more of the mathematics behind Cryptography. Even though this course didn't provide that, it was good. A good introduction to the field of cryptography.

Would have absorbed the course material more concretely if the instructor had slowed down on the pace at which concepts were being disseminated.

This course and the style of lecturing was nice but if there are more problem oriented type class is there then it would be more interesting

Could have been better if it the lectures could have been made more elaborate, also as a beginner it is hard to follow the terminology.

Although my head started spinning halfway through the course, it was filled with enough fascinating concepts to motivate me to finish.

Very difficult course if you have no previous experience with cryptoanalysis and recent stats, but good because it makes you think!

Excellent lectures. Mostly very easy to follow, but some mathematical points were ran through a bit too quickly and thinly.

some concepts introduced in this course can be non trivial and vague which requires a lot of googling searching.

I really enjoyed the journey I would say. I loved the course and it was really detailed and easy to understand.

Great Course but theories should be explained more but as for concepts based course its really great

Introduction intéressante et complète aux principes et systèmes essentiels de la cryptographie.

Very good introduction course with great supplementary materials and examples

I liked the course, the professor and the material, it was a fun course.

It was a great course to start with in this field.

much better than the Stanford course. thank you!

Very interesant, but basic material...

thank you very much..

just finished this course a few minutes ago and I can't believe that it came to an end so prematurely, it did not go over public cryptography systems and their core principles. also did not dive into symmetric cryptography algorithms and their mechanics, I wish I knew why.

thank you.

The Course was hard to grasp, Sometimes felt certain things were unclear like while explaining the theory that has numbers please add it on the screen. But It was one of the most educational and helpful courses on cryptography.

Take this course at your own risk!! Although course rated beginner, topics taught are not meant for beginners. You should already have previous knowledge in cryptography to successfully grasp knowledge given in this course.
