This list consists of 17 tutorials to learn modern cryptography. You can think of this list as a "Free Online Nano Book". You'll learn modern cryptographic algorithms ranging from Data Encryption Standard, RSA algorithm, Diffie-Hellman Key Exchange, Digital Signature Algorithm, Random Number Generation, Secure Hashing Algorithm (SHA) and more. Everything is 100% free.

This list starts out by describing what cryptography is, its various applications, branches and types of algorithms. Each section in this list focuses on modern cryptography algorithms currently in wide use. Sections 2 covers symmetric key cryptography, section 3 covers public key cryptography, and section 4 discusses other topics in cryptography and cybersecurity.

*Other versions*: Learn Cryptography: From Beginner to Expert is a more comprehensive list (this list is a subset) which also covers traditional cryptography algorithms not currently used and other historic notes.
