Encryption 101

Speaker: Stephane Richard, OPCUG

If you are using a computer and the internet, you are using cryptography. This presentation provides a basic introduction to cryptography. It covers the definitions of the terms used in cryptography and basic cryptographic processes. The basic mathematical functions used in cryptography are also discussed.

Once the basics are understood, a brief overview of an actual cryptographic algorithm is presented. Some applications of cryptography in our daily life are then presented such as Hypertext Transfer Protocol Secure (HTTPS) and digital signatures. Finally, the impact of quantum computing on classical cryptography is discussed.
