[edit] Description

md5deep is a set of cross-platform tools for computing hashes on any number of files. The tools can recursively process directory structures. MD5, SHA-1, SHA-256, Tiger, and Whirlpool hashes are supported. Each of the hash types has a corresponding tool with a name formed by combining the type with the word "deep."

The hashdeep utility has an audit feature that can take a list of known hashes and display the names of input files whose hashes do or do not match. Audit mode can identify new, changed, missing, or moved files. Moving files is considered a modification by md5deep and impacts the date of last modification for a file. File paths include the full path from root.

The md5deep command has a mode to break up big files (like audio and video) into pieces before running the hashes. The md5deep command also allows for a file size threshold so that you can ignore large files.

The program is a work of the US Government and is considered public domain. The code for Tiger comes from the libgcrypt project and is licensed under the General Public License (GPL). Because the vast majority of the program is public domain, the license of the project as a whole remains public domain. The Tiger code itself is still licensed under the GPL.

[edit] Platform

Binaries are provided for Microsoft Windows (7, Vista, XP, 2003, and 2000). The source code can be compiled on Linux, UNIX variants, and Mac OS X.

[edit] Documentation and user support

Man pages are available. Adding the -h flag to the path displays information about command use and available options.
