Hashing a file

WebA file can become corrupted by a variety of ways: faulty storage media, errors in transmission, write errors during copying or moving, software bugs, and so on. Hash -based verification ensures that a file has not been corrupted by comparing the file's hash value to a previously calculated value. 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 … 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. What it does allow you to do, … See more Threat hunting is also made easier thanks to hash values.
