Provides a comprehensive introduction to cryptographic history, current technology, best practices and known attacker techniques. A great deal of material is covered in a relatively compact program.
This course gives is perfect to start learning cryptography, explanations are detailed, topics carefully selected combining theory with real world examples and making emphasis in important details.

This must be an incredibly difficult course to try to teach in six/seven weeks. There's a ton of material to cover and I appreciate that the course touches on all of the basics of crypto that are actually in use.
My only complaint is that some of the questions on the quizzes were really repetitive week-to-week. In particular, every week features a question (usually #3, if I remember correctly) that had you choose which constructions out of five choices were "secure" as per the definition of security for that week's topic. The problem was that the correct and incorrect answers were always similar, even though the security concept for each week was different! In other words, there are some things that will NEVER be secure for any crypto system. Every version of the question had several choices that fell into this category. It got to the point that I usually got the question correct on the first or second attempt without even trying that hard. In reality, that question should have required a lot more brain power from me because those security challenges are actually sometimes very subtle and difficult.
But that's truly my only criticism. I loved the course and the programming assignments. I'll be keeping an eye out for any more courses taught by Dr. Boneh.

The theoretical part of the course, though dense and fast paced, was very informative. Being recorded it had the advantage for the student of being pausable and repeatable. The great disappointment was the programming part of the course, which I was very much looking forward to, in which the problems were great and have great potential to help the student learn something, but help was minimal (rather tautological, unrevealing, or plain condescending). Fortunately, the programming assignments were option and did not count towards the final grade. But I repeat, they do seem immensely valuable in their topic and difficulty as a learning experience, but guidance in a programming part of the course would be welcome for a change.

Overall, a great course! There's always room for improvement. Certain complex and critical concepts were glossed over way too fast in the lectures (with speech compression in the recordings to boot), while other introductory material was gone over too slowly. There is an answer string evaluation problem in the Q's & A's where the required answer must contain a bullet dot to represent multiplication (an 'x' is not accepted) but the standard computer keyboard does not contain a bullet symbol, you have to be in a word processor to create that. Also, there are correct alternative answers for Q#'s 6,9, &12 in the Week 5 Quiz that need to be re-evaluated.

Good course, covers pretty interesting material. The level is quite high and technical though, so I wouldn't call it introductory - you definitely need a basis in CS/algebra and a basic understanding of computer security in general.
Quizzes and videos are good but the course could use a better emphasis on coding (the programming assignments provided very little guidance and there's essentially no code in the lectures - probably by design but that can leave you hanging if you're looking for a practical rather than purely theoretical understanding of the topic).

Fast dialog made it so I had to watch the videos multiple times, copy of the discussion in text form helped.
The in the lesson questions, didn't know how to format the responses to make them work. Also when the session when to the question reply mode, it showed the question but covered up the graphic part of the question so you lost that context. Possible because I was full screen mode.
Well done all in all.

A very good course. The pace is quite high and the material is challenging. I think to get the best out of it you need to spend considerably more time than the course suggests each week and I was not able to do this. However, I have come out of the course with a good understanding of the basic concepts of cryptography and my interest in the subject has been piqued sufficiently to want to find out more!

The teacher is really an expert on the topic and I learned a lot from the course. The only criticism I'd offer is that some of the lectures make it hard to see the forest from the trees early on -- e.g., a lot of information might be provided early on in a lecture and the point is not really clear till the end. That said, I'm glad to have taken it and am considering taking the next part.

I really enjoyed this course! Symetric security was quite easy for me. But when it came to public key security I felt so lost because of all that deep math. Maybe it may have better and more detailed explanation, but maybe it just my problem with math (which I'm aware and aknowledge even without this course :D).But definitely worth time spent. Waiting for Cryptography II now.
