MAC / HMAC - Message Authentication Code / Hash Bashed Message Authentication Codes

In this video we explore the concepts of MACs. We first explore why Hashing alone is not enough, which leads us into the definition of a MAC. Then we define the most commonly used MAC... the HMAC.

// CHAPTERS //

0:00 - Message Authentication Codes
0:38 - Hashing isn't enough for Integrity
2:04 - Hashing vs Encryption (two different problems)
2:37 - MAC Simply Explained
3:58 - MACs vs HMACs
5:38 - MAC Algorithms
5:57 - MACs can be included with Encryption in AEAD Ciphers

Hey Ed. Can you share some love to the practical networking course as well. Feels like you have been busy with Cryptography. We miss you there as well 🙃😁

[marius-mihailionte]

Amazing video, amazing content on this channel, amazing TLS course, can't wait to see the Networking course.
Do you plan to design a comprehensive course about Cryptography?

Thank you.

Well, this is correct only if the end user doesn't know the original digest. If I publish the original digest, the end users can then compare the digest, and that way, find out if the file/message has been corrupted.
