How does it compare to md5deep (which also comes with sha1deep,
sha256deep, tigerdeep, whirlpooldeep)?


Quote from the website:

md5deep is a cross-platform set of programs to compute MD5, SHA-1,
SHA-256 Tiger, or Whirlpool message digests on an arbitrary number of
files. The programs run on Windows, Linux, Cygwin, *BSD, OS X, Solaris,
and should run on most other platforms. md5deep is similar to the md5sum
program found in the GNU Coreutils package, but has the following
additional features:

    * Recursive operation - md5deep is able to recursive examine an
      entire directory tree. That is, compute the MD5 for every file in
      a directory and for every file in every subdirectory.
    * Time estimation - md5deep can produce a time estimate when it's
      processing very large files.
    * Comparison mode - md5deep can accept a list of known hashes and
      compare them to a set of input files. The program can display
      either those input files that match the list of known hashes or
      those that do not match. Hashes sets can be drawn from the
      National Software Reference Library, iLook Investigator,
      Hashkeeper, or md5sum, and other generic hash generating programs.
      Users are welcome to add functionality to read other formats too!
    * Piecewise hashing - Hash input files in arbitrary blocks
    * File type mode - md5deep can process only files of a certain type,
      such as regular files, block devices, etc.
