Offered by Cybrary,
Cryptography (Cybrary)

What is Cryptography and how does it work? In this course, you will examine how cryptography is the cornerstone of security technologies, 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.

Often associated with privacy, Cryptography offers four basic services: Confidentiality, Integrity, Authenticity / Availability, and Non-Repudiation. This course offers practical examples for everyday use, to provide better understanding of these concepts.

Number Theory and Cryptography (Coursera)

We all learn numbers from the childhood. Some of us like to count, others hate it, but any person uses numbers everyday to buy things, pay for services, estimated time and necessary resources. People have been wondering about numbers’ properties for thousands of years. And for thousands of years it was more or less just a game that was only interesting for pure mathematicians. Famous 20th century mathematician G.H. Hardy once said “The Theory of Numbers has always been regarded as one of the most obviously useless branches of Pure Mathematics”. Just 30 years after his death, an algorithm for encryption of secret messages was developed using achievements of number theory. It was called RSA after the names of its authors, and its implementation is probably the most frequently used computer program in the word nowadays.
