Data Integrity - How Hashing is used to ensure data isn't modified - HMAC - Cryptography

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). This lesson is a free sample lesson from the the most effective TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals. 🔐 More details about the course: https://classes.pracnet.net/courses/practical-tls 🏢 Do you configure or troubleshoot TLS/SSL for work? If so, I'm willing to bet your employer would happily pay for this SSL training. Reach out if you'd like to coordinate an introduction for a bulk license purchase with your company.
