I liked it! Hard but worth it.

good but not for beginners ):

Nice learning experience.

i was a great experience

excellent course!!!!

Hard but worth it!

Excellent course

good instructer

还有很多课没有中文字幕

有部分视频没有中文翻译

very well

Great

good

NIce

Nice

The course is clear and goes at a sustained but correct pace. I really like the fact to show the weakness to understand what are the requirements of a secure PRF, PRP & co!

Optional programming assignments are really interesting unfortunately they take too much time to do and lack of guidance as it could be the case for the famous ML course. At least the first exercises should provide a development environment to get familiar with: hex, crypto libs, dictionary research, stats algorithms implementation ...

The first two weeks lack of in-video tests.

It is very nice to have some basic idea. But if supplemented with some practical based screen recording then may be that would be more interesting. If supplemented with reference to further reading materials for deeper understanding then that ware better.

The course was very good, but the pace was too fast, so eventually became the problem because it is

very difficult to follow. Anyway, it opened a new world to me and I'm willing to review many topics covered in this course

Very nice course , sometimes along there was some difficulty occurs but the support staff n teacher helps me a lot.Some practical implementation also missing from course.

a little bit hard for no computer basic people

Unnecessary questions are asked

There were too many repititions of tautological proofs. Should have been covered in 1/2 or more of a single session: this is how we reason about cryptography. Too much focus on low-level primitives which doesn't make sense if we are to never implement our own cryptography. Finally, as a general point it would be amazing if there were ungraded "practice sets" that came with answers: you work it work them out and look at the answers and if you don't understand you try to figure out what you can't get. You can ask questions on the forum without revealing anything. The focus should be on working problems. Then, the quiz needn't permit infinite retrials: working through the practice sets is where the learning would occur. As it is now, you listen to the lecture, read over the notes several times, and then try the quiz. I did the programming before taking the quiz: that was a chance to actual work with the crypto algorithms.

This isn't a beginners course. I dropped out in first week. I took every note I could and reviewed again and again. I really think the instructor is an intelligent man, but I'm not quite sure he understands how to teach well. I'm really disappointed that I didn't get to take anything away from this class.

El profesor es muy malo explicando, hay cosas las cuales no tenian sentido (creo yo que esto es porque justamente el profesor no sabe y explicar) y ademas las preguntas que hace en medio de los videos son ridiculas. Da preguntas sin haber antes explicado el conocimiento previo.

Very theoretical and mathematical and not enough real examples.
