WebFile verification tool based on MD5 checksum algorithm, with two interfaces and a free edition. Includes tool for creation and verification of data fingerprints, damage detection and file comparison. [Windows 98\Me\NT\2000\XP] WebA checksum algorithm, for example MD5 or SHA512, is used to generate a checksum from a bitstream. The checksum can then be recorded and used in the future to see if the bitstream has changed in any way. This is done by generating a new checksum at some time in the future or when the bitstream has been transferred between locations.
