 - [Cryptography - Stanford University](http://online.stanford.edu/course/cryptography) - This course explains the inner workings of cryptographic primitives and how to correctly use them. Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications.
 - [Cryptography I](https://www.coursera.org/learn/crypto) - 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.
 - [Cybrary Cryptography](https://www.cybrary.it/course/cryptography/) - This online course we will cover how cryptography is the cornerstone of security, and how through its use of different encryption methods, such as ciphers, and public or private keys, you can protect private or sensitive information from unauthorized access.
+- [Harvard's Cryptography Lecture notes](https://intensecrypto.org/) - An introductory but fast-paced undergraduate/beginning graduate course on cryptography, Used for Harvard CS 127.
 - [Journey into cryptography](https://www.khanacademy.org/computing/computer-science/cryptography) - The course of cryptography by Khan Academy.
 - [Practical Aspects of Modern Cryptography](http://courses.cs.washington.edu/courses/csep590/06wi/) - Practical Aspects of Modern Cryptography, Winter 2006 University of Washington CSE.
 - [Theory and Practice of Cryptography](https://www.youtube.com/watch?v=ZDnShu5V99s) - Introduction to Modern Cryptography, Using Cryptography in Practice and at Google, Proofs of Security and Security Definitions and A Special Topic in Cryptography.
