I'm adding a link to my new online cryptography course. This is a course that I teach each year to a large class of undergraduate students at the University of Waterloo (Canada).

Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications.
+- [Cryptography 101: Building Blocks](https://cryptography101.ca/crypto101-building-blocks/) - This introductory course (Fall 2024) by Alfred Menezes covers the fundamental cryptographic primitives: symmetric-key encryption, hash functions, MACs, authenticated encryption, public-key encryption, signatures, key agreement, RSA, elliptic curve cryptography.
 - [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.
