Amazing, The professor explain very well

excellent course

Thank you for taking the time to upload your videos. I hope you create a capstone course.

Cover every little details of Cryptography specially hash functions

Excellent introductory course

it is nice

The lectures were educational, and interesting without speaking down to you. I learned a lot without being overwhelmed

Excellent lectures. Very thoughtful and complete.

Excelente Curso en la cual a fortalecido mis conocimientos en el mundo de la Criptología. Saludos Mnauel Antonio Diaz Ricalde

A great course!

Good introduction. Beginner level with good resources.

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

much better than the Stanford course. thank you!

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

Very good introduction course with great supplementary materials and examples

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

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

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

thank you very much..

Nice and easy undergraduate course, but not useful for students seeking for a big picture of state-of-the-art cryptography. Content of this course is way too old.

Encryption/decryption of English characters are dinosaur technologies for telegraph, which itself has disappeared in modern communications.

Too many historical tales, too few modern technologies, and almost no technical details or math.

BTW, there are quite a few mistakes in slides, and the instructors don't response questions on discussion forums.

I don't believe students should start from the ancient age to learn modern cryptography, not very useful course in general.

too pooring , not interactive , it will be better if it integrate solving problem with programming

I think this is the worst course in Coursera which I have taken. The lecture is very bad , only see the teacher saying from begining to the end, without prepare any animation and slides. I can not remember so much usefull knowledge about the Cryptosystem in the course, I should self learning a lot of things from the link after each course. The professor did not give me any more value but only some link from wikipedia.
