HashTab Tutorial 2 – Using HashTab
In this short video tutorial we’ll demonstrate how HashTab can help you find corrupt or tampered-with files. We’ll look at three seemingly identical images and show you how HashTab can quickly compare them to find the odd one out.

Hashing algorithms are designed so that different files always produce different hashes. If you stop to think about this however, it is actually impossible that every file would have a different hash, since there aren’t enough numbers and letters in those little hash fingerprints to uniquely represent every possible file. When two different files have the same hash value, that’s called a hash collision. The probability of finding a hash collision by accident is extremely slim, especially when using MD5 or SHA-1 hashes, meaning you can be sure beyond most reasonable doubt that your files are the same if the hash values match.
