Best Free Hash Utility
Hashing is the process of computing a fixed-length message digest from a data stream usually for the purpose of validating, authenticating, or digitally signing that stream. The stream could be a disk file, an email message, or packets of data in network transport. Hashing is not encryption because the message digest cannot readily be transformed back into the original data from which it was computed. Instead, hashing is a mechanism for representing a block of data in a predictable way by the use of a standard, public algorithm.
