Hashdeep is a set of tools to compute MD5, SHA1, SHA256, tiger and whirlpool hashsums of arbitrary number of files recursively.

The main hashdeep features are:

* It can compare those hashsums with a list of known hashes; * The tools can display those that match the list or those that does not match; * It can display a time estimation when processing large files. * It can do piecewise hashing (hash input files in arbitrary sized blocks).

This package is useful in forensics investigations.
