FISH is a free file integrity tool that creates a file signature database (default db.xml) for the file types (ie. exe, dll, sys) specified in the configuration file (config.xml). This signature database is then fed to the FISH (sigdb in the config) at a later date to check for the presence of new, deleted and altered files. A brief summary is written to the console and a report (default report.xml) is created, highlighting changes.
