Description

Many aspects of data security today rely on some forms of cryptographic algorithms, making it very important to understand the concepts and details behind the specific cryptographic algorithms that are being used. In this module, we will look at the foundations of cryptography, the different algorithms and approaches, and will attempt to achieve deeper understanding on how the algorithms work and how they can be used to perform specific tasks. At the end of this module, the attendees are expected to know not only what algorithms to use and where, but to also be able to understand why, and with what kinds of risks, if any.
