Interesting course and a good overview about cryptography. The last week is a little bit too fast-paced if you are complete newbie.

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

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

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

Good introduction. Beginner level with good resources.

Excellent lectures. Very thoughtful and complete.

great course with intro to basic concepts

Amazing, The professor explain very well

Excellent introductory course

excellent course

A great course!

it is nice

Really good start into the world of cryptography! However at times (especially at the hashing part) it gets really complex and you'll need to listen and read it multiple times, and find some simplified examples outside of the course to really understand what happening.

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

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

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.

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

Very good introduction course with great supplementary materials and examples

much better than the Stanford course. thank you!

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.

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.

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