About this Course

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.

LOVE this course and cannot wait to start Part II: Professor Boneh is a wonderful professor and he truly enjoys teaching this course. Some mathematical background is required, however, and some of the formulation at this points look unnecessary (but also necessary for being rigorous)

I'm a software developer - I took this course because I wanted to demystify cryptography, and it delivered 100%. It describes fundamental cryptographic primitives, how to use them (and how not to use them) with real-world examples, as well as the theory behind why they are secure, and what "secure" actually means.

There is a fair amount of mathematics involved - everything is covered in the course, but someone with a background in mathematics will definitely have an easier time.
