Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption....

Excellent course! I can recommend this to anyone who is not afraid of some basic math. But a person interested in cryptography should not be afraid of math, yielding that this course can be recommended to anyone interested in cryptography.

Challenging, yet very informative. Dr. Boneh is extremely good at explaining the concepts of basic Cryptography. I especially liked the "proofs by images". Will be definitely going for Crypto 2 as soon as I have time available for it.

When someone explains concepts and ideas in such an easy way, it means he/she understands fully what he talks about; this is the case of Professor Dan Boneh; I widely recommend this course for anyone interested in Cryptography topics.

One of the best courses of my life, well planned, very up to date, with good examples, good academic level. Very recommendable for those who want to know the new discipline created in the term of the last century called cryptography.

I learned a lot from this course. From my perspective (background in math), Boneh made a good trade-off between a rigorous approach and covering real-world crypto - both is covered to a sensible degree. Looking forward to part 2.

Great course.

The material is explained masterfully. The exercises are interesting, challenging and effectively strengthen the knowledge acquired from the lectures. One of the best courses I've taken both in university and online.

It 's the second time I follow this course and I still find that so amazing. I'm waiting Crypto II until a year and I hope it will be released soon... Thanks Pr Boneh for sharing your little (for you) big (for me) knowledge !

Really cool course that was fun and very informative. Really well designed quizzes, homeworks, and programming assignments. It was pretty difficult compared to most online courses but I guess that's expected from Stanford...

Time consuming and hard work but very rewarding. Took me several attempts to finish (other life commitments kept getting in the way).

Will be doing it at least once more to try and finish all the programming exercises too :)

Can be difficult at times but the concepts are definitely rewarding. The psets were creative and effectively asked students to apply concepts. Dan Boneh is articulate as always and knows how to get the subject across.

I started this course a long time ago, it feels great to finish it. There was a lot of theory, but the message of 'don't try it build it yourself' was driven home. I look forward to the other topics in cryptography 2.

Great course! I like the content and organization of the course. However, the last two weeks of the course were somehow complicated to understand. I will continue studying security and I am waiting for Crypto II.

Awesome course. I would recommend anyone that is into the Cyber Security field to study the course and realize the beautiful of Cryptography. I cannot wait to study more *magic* in the second course of this.

I learned a lot. The Prof. Boneh explains everything very clearly (like the way of presenting). A course materials covers a lot of crypto staff, and are very comprehensive. I can't wait for Cryptography II.

Really comprehensive. Explain cryptography from bottom up. After learning the primitives I have a better understanding over many cryptosystems. Appreciated it professor! Looking forward Cryptography II!

A really interesting and in-depth course. It is pretty challenging and requires good math/proof skills, but still quite fun. The course could use more study materials, for example lecture notes.

Really interesting, provides the basic grounds for understanding a lot of discussions out there. Wikipedia can be useful as a reference, but here I was able to learn about semantic security etc.

Very comprehensive overview of Cryptography. Though a bit too mathematical for me, the gist of it is very helpful to understand cryptocurrency protocol design of Bitcoin, Ethereum, Monero...

Excellent course. I've worked with cryptographic methods and practice for many years, but this course provided me with a stronger understanding of the underlying theory than I'd had before.

Great grounding of the cryptography basics, but does require a decent understanding of basic computing (bits, XORs) and some reading on finite field maths beforehand would definitely help.

Great Instructor, really enjoyed his style of expanding the math "sentences" into lay English EVERY SINGLE TIME! That really helped this learner "go with the flow" as my background is CS.

The course gives fundamentals of Cryptography. But I would say that it dig very deep with fundamentals so I would highly recommend this course if you need/want to understand Cryptoraphy
