Version 3.6-1 of 'md5deep' has been uploaded. This version is the
initial release of md5deep for Cygwin.

The following was excerpted from the Introduction section of the md5deep
project homepage, at http://md5deep.sourceforge.net/


'md5deep' is a set of programs to compute MD5, SHA-1, SHA-256, Tiger, or
Whirlpool message digests on an arbitrary number of files. md5deep is
similar to the md5sum program found in the GNU Coreutils package, but
with additional features, including:

    *  Recursive operation - md5deep is able to recursively examine an
entire directory tree. That is, compute the MD5 for every file in a
directory and for every file in every subdirectory.

    * 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 Encase, the National Software
Reference Library, iLook Investigator, Hashkeeper, md5sum, BSD md5, and
other generic hash generating programs.

    * Time estimation - md5deep can produce a time estimate when it's
processing very large files.

    * Piecewise hashing - Hash input files in arbitrary sized blocks

    * File type mode - md5deep can process only files of a certain type,
such as regular files, block devices, etc.

This package also includes 'hashdeep', a program to compute, match, and
audit hashsets. With traditional matching, programs report if an input
file matched one in a set of knowns or if the input file did not match.
The state of the input files compared to the set of knowns can often be
more complex than anticipated. It's possible to have matched files,
missing files, files that have moved in the set, and to find new files
not in the set. Hashdeep can report all of these conditions. It can even
spot hash collisions, when an input file matches a known file in one
hash algorithm but not in others. The results are displayed in an audit
report.
