This is md5deep, a set of cross-platform tools to computer
hashes, or message digests, for any number of files while
optionally recursively digging through the directory structure.
It can also take a list of known hashes and display the filenames
of input files whose hashes either do or do not match any of the
known hashes.

This version supports MD5, SHA-1, SHA-256, Tiger, and Whirlpool
hashes.

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.
