md5deep and hashdeep - Latest version 4.4

Quick Links


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 has the following additional features:

hashdeep is a program to compute, match, and audit hashsets. With traditional matching, programs report if an input file matched one in a set of knows or if the input file did not match. It's hard to get a complete sense of the state of the input files compared to the set of knowns. 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.

The hash set audit process was described in the paper Auditing Hash Sets: Lessons Learned from Jurassic Park published in the journal Digital Investigation.

For more details and some examples of using hashdeep, check out the hashdeep getting started guide.

Supported Platforms

The programs are distributed as binaries for Microsoft Windows (7, Vista, XP, 2003, and 2000 are supported) and as source code. The source code should compile nicely on just about any platform, including Cygwin, Linux, FreeBSD, OpenBSD, Mac OS X, OpenSolaris, HP/UX, etc.

Note that several operating systems support an automatic installation of md5deep through packaging or ports. See the Automatic Installation section of the getting started guide for details.

Microsoft Windows NT and Windows 9x are no longer supported. The last version that works on Windowx 9x was version 1.13. Windows 3.x was never supported.

Stable Version

The latest stable versions of md5deep and hashdeep are now distributed on the GitHub site,

Beta Version

There is no beta version of md5deep right now. If you have any problems or would like to see something added to md5deep, please send mail to the developer at or visit the Sourceforge project page .

Older Versions

Although older versions of md5deep and hashdeep are available for historical purposes, you shouldn't use these unless you have a truly compelling reason.

The Hashing Algorithms


To quote the executive summary of RFC 1321, the official MD5 specification:

[MD5] takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.
Some weaknesses have been found in MD5 and the above statement may no longer be accurate. Please check the current status of MD5 for more information.

The algorithm was originally developed by Professor Ron Rivest of the Massachusetts Institute of Technology. More information on the algorithm can be found in RFC 1321 and in the RSA Cryptography FAQ.


To quote the start of RFC 3174:

[SHA-1 is used] for computing a condensed representation of a message or a data file. When a message of any length < 264 bits is input, the SHA-1 produces a 160-bit output called a message digest.
The algorithm was originally developed by the National Institute of Standards and Technology and is officially defined in FIPS 180-1, published in 1995. (The SHA-1 algoritm also appears in FIPS 180-2, published in 2002. Although the algorithm was not changed, some of the notation was changed to make it more consistent with other algorithms.)

Some weaknesses have been found in SHA-1 and the above statements may no longer be accurate. Please check the current status of SHA-1 for more information.


To quote the start of FIPS 180-2:

This Standard specifies ... secure hash algorithms ... for computing a condensed representation of electronic data (message). When a message of any length < 264 bits is input to [SHA-256] , the result is an output called a message digest.
The algorithm was originally developed by the National Institute of Standards and Technology and is officially defined in FIPS 180-2, published in 2002.


Tiger is a hashing function developed in 1995 by Ross Anderson and Eli Biham. The algorithm produces a 192 bit output, but truncated versions of 160 and 128 bits, called Tiger/160 and Tiger/128 also exist. A second version of the algorithm, Tiger2, is identical to the original except for the padding method. The padding in Tiger2 is the same as MD5 and SHA-1. You can read more about Tiger at the official Tiger website.

Tigerdeep, the program included in this package, produces Tiger/192 hashes in the same format as the NESSIE standard. Use the NESSIE formatted test vectors for Tiger to check your version of tigerdeep.


According to the official Whirlpool homepage,

Whirlpool is a hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto that operates on messages less than 2256 bits in length, and produces a message digest of 512 bits. ... the final version (called simply WHIRLPOOL for short) was adopted by the International Organization for Standardization (ISO) in the ISO/IEC 10118-3:2004 standard.

About the developer

These programs were written and are now maintained by Jesse Kornblum. At the time md5deep was originally written, Mr. Kornblum was a Special Agent with the United States Air Force Office of Special Investigations (AFOSI). As such, the program is considered to be a work of the United States Government. Under 17 USC 105, works of the United States Government are not eligible for copyright protection.
