My Digitization Vendor Always Sends .md5 Files As Part Of Their Deliverables

5 December 2015

A file’s checksum is a specially generated hash based on a computation of all of the individual bytes that make up the file. A variety of algorithms exist that can be used to perform this computation, e.g., MD5, SHA-1, or SHA-256. For example, an MD5 checksum is a 32-bit string that may look something like this: ff839faf604272ba094741b62c7e4254. Because the computation takes into account every byte of a given file, if any bytes change for a given file, then the outcome of the computation will produce a different hash. Only an identical set of bytes will produce the same hash repeatedly when processed through the checksum algorithm in use.
