Md5deep 1.12 - Compute MD5 message digests on an arbitrary number of files.

Md5deep is a cross-platform program to compute MD5 message digests on an arbitrary number of files. The program is known to run on Windows(tm), Linux, FreeBSD, 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 andf 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.
