WebIn computer science, a hash list is typically a list of hashes of the data blocks in a file or set of files. Lists of hashes are used for many different purposes, such as fast table lookup ( hash tables) and distributed databases ( distributed hash tables ). A hash list with a top hash. A hash list is an extension of the concept of hashing an ... WebComputer and Network Security by Avi Kak Lecture15 Back to TOC 15.3 WHEN IS A HASH FUNCTION CRYPTOGRAPHICALLY SECURE? A hash function is called cryptographically secure if the following two conditions are satisfied: – It is computationally infeasible to find a message that corresponds to a given hashcode. This is sometimes …

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.
