hashdeep is a command line tool for generating and verifying file hashes across large collections of files.
It’s designed for integrity checking and audit-style workflows, letting you recurse through directory trees, build hash inventories, and compare current files against previously recorded hash sets to identify matches, missing files, and unexpected additions.
This is free and open source software.
Key Features
- Supports MD5, SHA-1, SHA-256, Tiger, and Whirlpool hash algorithms.
- Recursively processes directory trees to hash large sets of files.
- Can compare input files against known hash lists and report matching or non-matching files.
- Includes an audit mode that checks a file set against a known baseline and reports discrepancies.
- Provides cross-platform tools with support for Windows and POSIX systems.
