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....

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.

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.

A great introduction to cryptography. The material is all contained in the lecture videos making it easy to work through. The notation becomes a little hard to keep track of following week 4 but that's probably my fault for not committing it to memory thoroughly enough

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.

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

The course is very well structured and gives overview of whole flow and systematically prepares us to understand each of the part. I am really looking forward to Crypto II, where will be described more things about certificate and new exchange protocols. Thank you.

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.

There is no reason why this course deserves anything less than 5 stars.

Everthying is nicely explained and there is so much to learn.

A difficult, but rewarding course. Much more theoretical than I was expecting, and I would suggest a strong Maths background for anybody considering taking the course.

This is a fabulous course. Professor Boneh did an admirable job teaching the basics of modern Cryptography. Modern Cryptography was born at Stanford University founded by Martin Hellman and two students. It used at first intuitive ideas linking complexity theory to cryptography. The old cryptography, that is cryptography at around the Second World War was a a rigorous theory based on Information Theory and founded by Claude Shannon. Modern cryptography was based on the idea that if a cryptographic system cannot be broken in billions of years, then it is for all practical purposes just as secure as a theoretically unbreakable system. In the last 30 years or so the proper definitions were found to make this intuitive idea precise, making modern cryptography a rigorous science. Professor Boneh presents this rigorous theory in this course.
