Welcome to the bit_rot_detector wiki!

bit_rot_detector, or brd, is a tool to scan a directory tree and check each file for corruption caused by damage to the physical storage medium or by damage from malicious programs. Files are fingerprinted using the SHA-1 algorithm. File fingerprints, sizes, and modification times are stored in a SQLite database.

In addition to checking files for corruption, brd provides the ability to search the database for duplicate files and subtrees, as well as diff subtrees.

See LICENSE for information regarding use and distribution.
