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.

Really good course, instructor provides real life examples a tries to avoid the mathematic abstractions to minimum - relying rather on intuition and pictorial examples.

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.

Very clear yet challenging introduction to basic cryptography concepts. Be sure to take notes and practice as much as possible with the modular arithmetic presented.

I enjoyed the not-too-much-mathematical approach of diging into crypto basics. All popular (practical) questions arise and are discussed in understandable manner.

I really enjoyed Dan's lectures; in my opiniont the course is more mathematical/theoretical and less real world examples. But that's the spirit of academy! :)

Very good course, it's easy to understand the concepts and the programming assignments help to understand the details of the implementation of the algorithms.

Great course. It's in depth and requires some effort, especially if working full time, but really great theory based overview of common crypto concepts.

I think this course was an ecelent course. Too short and too many information. High-level teach by amazing Harvard professor. Thanks Dan Boneh.
