Description

Digital Evidence Laboratory specialists created the HashKeeper software in 1998 to expedite the analysis of electronic media by reducing the number of files to be analyzed during the course of an investigation. HashKeeper works by storing MD5 hash values, or "digital fingerprints", of common software applications and compares those hash values against the files encountered in a seized system.
