Hyper Hasher is a utility that allows you to calculate hash/checksum and HMAC values for any file on your system, as well as for a text string. Hash and checksum values are used to verify the integrity of computer files, as well as to uniquely identify them.

The process of hashing a file basically involves reading the entire file, and applying various mathematical algorithms to its contents, in order to produce a text string (the "hash"). The hashing process does not in any way alter the files being read. Hyper Hasher is capable of calculating 26 different hashes and checksums.
