WinMD5- Compute MD5 Hashes on Windows

WinMD5 v2.0 is a free Windows (98, 2000, XP, Vista, 7) utility for computing the MD5 hashes ("fingerprints") of files. These fingerprints can be used to ensure that your file is uncorrupted. Simply drag the files and the MD5SUM signature file to verify the integrity of your download.

About WinMD5

If you've downloaded a large file over the internet, perhaps the latest RedHat CDs, you may have wondered if your download completed correctly. Are the copies on my machine exactly the same as the ones on the server?

MD5 is the name of a "hashing" algorithm which can answer this question. MD5 hashes are fingerprints of files. You can compare the fingerprints of two files to see if the files themselves are the same.

In order to be useful, you have to know what the correct fingerprint for a file is... otherwise, you cannot tell if your file is right or not. If you're downloading a large file, look for a file named "MD5SUM", or something similar. This file contains the correct fingerprints. Dragging an MD5SUM file onto WinMD5 causes the fingerprints to be compared automatically.

This program allows you to compute the MD5 hashes of files. It also makes it very easy to compare the fingerprints against the correct fingerprints stored in an MD5SUM file. RedHat, for example, provides MD5SUM files for all of its large downloadable files.


WinMD5 is free. You may redistribute it provided you distribute the complete distribution, including documentation, without any modifications. WinMD5 comes without warranty of any kind.

Current version:

The required .NET runtime is available from Microsoft, in the event you do not have it installed already.

Archival versions

If you do not have the .NET runtime installed and do not wish to install it, consider running version 1.1, available above.


It complains about a missing dll, mscorlib.dll or something like that!
Sounds like you don't have the .NET framework installed.
