Hash file meaning

WebA file hash is a unique signature for data that helps to identify it in a verifiable way. A file hash can be used for various purposes, including authentication and deduping (de-duplicating) data. Hashes are a fundamental tool in computer security as they can reliably tell us when two files are identical, so long as we use secure hashing algorithms that avoid collisions. Even so, as we have seen above, two files can have the same behaviour and functionality without necessarily having the same hash, so relying … See more Hashes are the output of a hashing algorithm like MD5 (Message Digest 5) or SHA (Secure Hash Algorithm). These algorithms essentially aim to produce a unique, fixed-length … See more Hashes cannot be reversed, so simply knowing the result of a file’s hash from a hashing algorithm does not allow you to reconstruct the file’s contents.
