Fingerprint

Fingerprint is a general purpose data integrity tool that uses cryptographic hashes to detect changes in files and directory trees. The fingerprint command scans a directory tree and generates a fingerprint file containing the names and cryptographic hashes of the files in the tree. This snapshot can be later used to generate a list of files that have been created, deleted or modified. If so much as a single bit in the file data has changed, Fingerprint will detect it.

Fingerprint can be integrated with other tools to ensure the integrity of an entire network of computers from a single point.
