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.

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.

This is a fantastic introduction to the world of cryptography! You learn about the basic concepts of encryption, authentication, authenticated encryption, public and private keys and the underlying mathematical principles that (should) make it hard to break the ciphers! You also learn about historical developments, real world applications and current challenges that would bring you instant fame in the crypto world. Also it is not a disadvantage if you really love solving puzzles!

Very interesting course, even though I come from engineering background and wanted to explore cryptograpy for fun, managed to understand the concepts and the course built a strong cryptographic foundation. Big thanks to professor Dan Boneh and all the mentors that answered questions in forums. Hopefully see you all in Cryptography II

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.

This was a great intro cryptography course for someone with a strong mathematics background like myself! Not fluff, Dan Boneh cuts straight to the point. Every lecture is brilliantly presented and explanations are always thorough and easy to follow. Topics are relevant for real world applications. Amazing course. Can't wait for part 2.

This guy is SO MONEY!! He makes it look like you could do cryptography in your sleep. Which I am almost convinced he must do ;~D
