Is there any small utility that integrates with the Windows shell and computes md5 of files on demand? I'm too lazy to launch the command line :D.

Edit: Just found this with a Google search on "md5 shell integration": http://www.fastsum.com/press/windows-md5-checksum-utility.php. I'd still be happy to hear what you use.

I'm using HashCheck which integrates itself as a property page for files and includes a context menu to compare against hash check files (SFV).

It is free, and the source is available.

this one is very nice , i tested it on 1GB file and its faster then Summer Properties. –  Karim Jul 3 '10 at 22:45
    
I'm using this too. And it supports other hashes as well. –  Svish Sep 30 '10 at 11:51

Hilarious app. Definitely the best. It can check the hash with a doubleclick on the created file.MD5! And it remembers what files were hashed. –  Pavel Radzivilovsky Dec 23 '10 at 14:26

AVG is flagging that the core Windows Utility has been changed - that is the sort of thing that malicious software often does. –  dunxd Nov 20 '12 at 10:15

Free, open source, integrates with property page and explorer context menu, has an .MD5 checker and supports SHA-1. Not to mention it's just 85kb and runs really fast. This application is absurdly great, thank you! –  Şafak Gür Feb 26 at 9:59

Here's one I've used before that integrates nicely with Explorer's "Properties" dialog: Summer Properties. It's open source, and an x64 version is also available.

I also like Safer Networking's FileAlyzer, which provides additional features as well. But just for checksums, Summer Properties is lightweight and does the job.

I had used this ages ago but had forgotten about it +1 for the reminder. –  Nick Josevski Feb 17 '10 at 12:16

Great tool. +1. I wish it had "copy" buttons too =x –  Pavel Radzivilovsky Oct 3 '10 at 15:21
    
The only problem with this is that it does not support folders or groups of files. It is also out of dvlp –  Pavel Radzivilovsky Dec 23 '10 at 12:47
    
Another problem with it is that you can't paste an hash into it and see if it matches –  Jonathan Mar 23 '11 at 16:33

Nirsoft's HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system. You can easily copy the MD5/SHA1 hashes list into the clipboard, or save them into text/html/xml file.

HashMyFiles can also be launched from the context menu of Windows Explorer, and display the MD5/SHA1 hashes of the selected file or folder.

HashMyFiles is freeware and portable.

+1, Seems like a new one -- the last time I checked (before moving to a command line md5sum version) was FastSum -- but, it was sort-of trialware and nagged a lot. HashMyFiles is good because it allows drag-and-drop of multiple files and export to CSV (both important features). Don't think I had seen it when I found FastSum a couple of years back. –  nik Dec 30 '09 at 2:15
    
that's right, HashMyFiles is a fairly recent addition to NirSoft's portfolio, it was first released in 2007. –  Molly7244 Dec 30 '09 at 9:05
    
…that integrates into Windows [Explorer] –  Synetech Dec 19 '13 at 5:10

MD5 Context Menu does exactly this. It adds an MD5 option to the context menu of files:

MD5 context menu is a freeware shell extension for windows which displays the MD5 hash sum of the selected file.

It says it's compatible with Windows 95, 98, ME, NT, 2000, and XP, although it works for me perfectly fine on 7. It's a tiny download (238KB) and includes everything you need.

"Because of a serious bug in the last version of our tool for large files with sizes > 2^31 bytes (~2.1GB) we currently do not provide the download anymore." –  Taha Jahangir Oct 11 '13 at 4:35

HashTab 3.0 is a free shell extension that calculates many checksums, including MD5. It's integrated as a new tab in the File Properties.

Something like this: winmd5sum.
This one's also nice: sendtoMD5 - right click, send to ..., and it gets you the result.

Cygwin contains an md5sum.exe utility that should do what you want.

Unfortunately being command line based, it doesn't integrate with the Windows Shell. –  Cristian Ciupitu May 21 at 19:38

You can use MD5sums for Windows, a download of only 28Kb (cygwin might be overkill if all you want to do is compute MD5s).

The easiest way to use it is to use Explorer to drag and drop files on md5sums.exe to obtain their md5 hashes.

HashTab intergrates with windows nicely, you just go to the properties of any file and HashTab is a new tab that will calculate md5, sha-1, CRC32 and a number of others. If you have a sum in your clipboard it will auto compare it to the file's sum.

I like digestIT, although it seems to be fairly old and maybe not maintained.
