Cryptography is one of the most important branches of maths in the modern age.

Almost everything that requires security/secrecy in our life relies on it. However the basics of it aren't well understood by many, even those who work with it daily, such as System Administrators.

Cryptography can get very complex and way beyond anyone who hasn't got a doctorate, however a basic grounding in some principles behind it is very useful (and interesting, if you're that way inclined)

I came across these videos whilst browsing Reddit which I would recommend to anyone that wants to learn more.
