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....

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.

Cutting edge cryptography topics. Good explanations and slides, but pause button is highly recommended. Can be a bit too mathematical for the general public, and not very formal for mathematicians.

This course is definitely worth the time -- the explanations are very logical with refined transitions from topic to topic. I enjoyed every part of it including the tests and programming assignments. Thank you very much for filling many gaps in my knowledge!

This is the best course for a beginner especially in terms of understanding the concept of security in relation to encryption schemes that are used in practice today. This course best explains security of encryption algorithms. Looking forward to crypto II.

Honestly, a great course in Cryptography. The professor is very lucid and clear. Notation isn't too heavy and the ideas in this course are explained very clearly. Yes, you might have to pause and rewind some of the videos, but that's just because it's math.

Great class that provides the basic understandingof cryptography and what the common pitfalls (and reasoning behind) that most developers encountered. Strongly recommend for anyone who needs to deal with security and/or privacy issues in system design.

It was awesome! I learned a lot and the professor pointed out useful additional reading. Since I'm going to do my PhD in cryptography, it's really important to me. And I god financial support to finish the course. Thanks professor and coursera team!

This course was an excellent way to put all the ad hoc crypto knowledge I've picked up over the years on to a sound footing. It was very nicely structured and presented, and the optional programming challenges were great. Looking forward to Part 2!

At first, it seems like there is a lot of concepts to digest but as the weeks pass, we can recognize some patterns in the various encryptions and way in which we create a challenger-adversary game. It was interesting and truly informative. Thanks!

I always wanted to know a bit more about cryptography, and this course is perfect as a starting point. It balances theory with practice. The part I enjoyed the most was the programming exercises where you could use some of the theory in practice.

Great course. The amount of math is just enough for providing a solid theory background. All the materials are presented in a logical order and enhanced with good examples. The size of the course allows get accounted with essential fundamentals.

The lectures are clear and well made. The assignments, especially the optional programming assignments are interesting and helpful for understanding the theory learned in the lectures and seeing some ways they can be applied. Awesome course.

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.

This course is a little difficult compared to any other courses i have taken in coursera. Very vast, problematic but fun to learn and Try to complete coding assignments, they are help in understanding the encryption techniques very well.

Exceptional material for anyone wanting to add Cryptography to their toolbox. Previous maths knowledge doesn't hurt. And some basic coding knowledge, if you wish to engage with the additional material.

I eagerly await v.2 of this course!

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.

Well organized course with excellent problem sets and exams. Covers basic crytoanalysis, MAC, symmetric cipher, key exchange and asymmetric encryption. Great introduction to the topic with a relatively low level of mathematics.

Without any hesitation, one of the best computer science courses I've ever had. Dan is brilliant, straight to the point and very pedagogue. Thank you for this wonderful course, and looking forward to studying Cryptology II soon :)

Amazing course. Learnt a lot regarding crypto basics and concepts behind it. The math was a bit tough at some points but the explanations were excellent so that there is little to no doubts left at the end. Can't wait for Crypto 2

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.

Dan Boneh is an excellent instructor - as you start wondering some questions during his lectures, the next minute he would answer it in the video. Some sections might be a bit too maths-heavy for those with no maths background.

Incredibly well explained- I learnt so much from a base of little knowledge and the format was really good. Weeks 7 and onwards are mentioned to be in a different course so I'll have to find that as well. Thank you very much!

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 !
