MD5 Checksum Calculator was designed to be a small freeware utility for calculating the MD5 (Message Digest number 5) checksum values of specified files.

The algorithm takes as input a message of arbitrary length and produces as output a 128 bit (16 byte) "fingerprint" of the input (also known as a "message digest", "checksum" or "hash"). It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

RiMD5 is a very simple utility and, for this reason, does not demand any installation utility. Simply unzip all files to any folder and run the executable file (usually, "RiMD5.exe").
