Covid Cryptography 2: Message Digests
Channel: MathMesh
Date: 2020-04-22

In the previous module we looked at Work Function and how keys play an important role in cryptography, the more keys, the more functionality. In this module we look at how we can do some really interesting and useful cryptography without using any keys at all.

Message Digest functions are the basis for many important cryptographic and non-cryptographic applications and services including Google, Akamai, the GIT source code manager and of course BitCoin and every other Blockchain type scheme.
