Data Integrity Explained: How Hashing and HMAC Protect Your Data 🔒

Data Integrity seeks to assure that data has not been modified in transit between a sender and receiver. This assurance is provided using a Hashing Algorithm... but not simply by itself, that leaves you open to an attacker modifying your message and re-calculating the digest. Instead, something else must be done in addition to Hashing.

In this video, we discuss that "something else". This will have us introduce the concept of a Message Authentication Code (MAC), and the most common implementation of a MAC known as the HMAC (Hash Based Message Authentication Code).
