Signatures - What and why are they?

In this video we take a look at Digital Signatures. We explain what they are, show you examples of what types of things are signed, and discuss how they provide Integrity and Authentication to what is signed. We then compare them to HMACs and MACs, which also provide Integrity & Authentication, but have a slightly different use case. // CHAPTERS 0:00 - Intro 0:12 - Simple Definition 0:38 - Signatures are created with Private Key & verified with Public Key 1:31 - Anything can be signed 2:04 - Integrity and Authentication 2:39 - Signatures vs MACs / HMACs 4:23 - Signature Algorithms - RSA DSA // FULL SERIES - Cryptography Essentials // This video is part of a 16-part series covering the essentials of modern Cryptography.
