Hashing, Hashing Algorithms, and Collisions - Cryptography - Practical TLS

Hashing, or a Hashing Algorithm takes "something" (a message, a file, a certificate, computer code, anything) and turns into a smaller, representational sample of the original something. The result of a hashing algorithm is known as a Digest (among other names). To check if two files are perfectly identical, you can simply run them both through a hashing algorithm and compare the digests. If the digests are the same, then you know both files are also identical. In the rare cases that multiple files result in the same digest... you have what's known as a Collision. And while rare, collisions are unavoidable. 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.
