Introduction to Cryptography part2 - Asymmetric vs Symmetric Encryption

This is the second of my videos on an introduction to cryptography. My earlier video gave a brief overview of cryptography, some of the history behind cryptography and an example using ROT13.

Part 1 about Cryptography, history and importance:

In this video I’ll look at the importance on cryptography today and some additional concepts relevant to modern security.

The video includes the importance of cryptography in the CIA security triad.
Cryptography in various states at rest, in use, in transit.
Encryption algorithms. Kerckhoff's principle vs security by obscurity.
Differences between codes and ciphers.
