DISCUSSION: Checking the md5sum in Windows
 

This thread is to discuss the article titled: Checking the md5sum in Windows

I will counter with Microsoft’s MD5 sum checker.

Microsoft FCIV program to check MD5 sums
The FCIV utility runs on Microsoft Windows 2000, Windows XP, and Windows Server 2003.

fciv.exe c:\ -r
FCIV -md5 -sha1 path\filename.ext
FCIV -md5 -sha1 c:\windows\system32\shdocvw.dll

For further information please check out the “Availability and description of the File Checksum Integrity Verifier utility” Article 841290 at the Support.Microsoft.com site.

I've never used that utility, so I wasn't familar with it. (Regarding M$'s util)

I just re-read my post. I hope it didn’t come off to hard. It is just another option. As long as the numbers come up correct, it doesn't matter what MD5 sum checker is used.

Better winmd5sum checker ?
 

Well I read all other posts and I believe this to be a far better md5sum chacker for Windows users - and it gives a simple GUI. This is very basic and very suitable for those Win users who do not want all the frills that other md5sum checkers may offer _ OR _ be forced to use the command line from within Windows.

PLEASE NOTE:-
This is TOTALLY free and if you look at the bottem you will see that they offer the SOURCE as well as a Binary - So I guess that makes it "open source" ?

Go here:- http://winmd5sum.solidblue.biz

NB:
(1)
When you check say a 700 Mb file it "will" take a little while for it to generate the alpha-numeric number. After all it is quite a big file, so what would you expect, the short time it takes to generate the alpha-numeric number also happens when doing it in Linux from the command line. So do not think that Winmd5sum has looked up your computer, just wait for it to happen.
(2)
If you open with Wordpad the small XXXXXXX.md5 txt type file that has the alpha-numeric number in it, you can then copy and paste that number into the "lower section" of the Winmd5sum and then just click "Compare". It will tell you if the number you first generated from your (say) 700 Mb file is exactly the same as in the XXXXXXX.md5 txt type file (easy)

This is so simple to use, I would recommend it over and above all other Windows md5sum checkers, for those that just want an easy and simple thing to use. Forget all the others, this is Free, very small to d/l, self-installing, does the job real well.

minimal GW system
 

You can look at the minimal GW system for Win. It incorporates all linux cmds, well basic ones. You may install rpm's too.

Try the AccuHash 2.0 from accuhash dot com

Or use the Nero MD5 verifier
 

Microsoft's FCIV and most other Windows tools do not support text mode of md5sum or sha1sum.
Neither WinMD5Sum, AccuHash 2.0 nor Nero's Verifier support all modes.

Hence I use a GNU build from the GNU Win32 project

If you need to calculate MD5 sum for a string you can use the md5sum tool on http://md5.md/ website.

@Marko77:
Thanks for the webpage tip. Will come in handy when needed.

But I need text mode checksums for checking text files (e.g. source code) from different systems that have different line endings (Win = CRLF, Linux = LF, Mac = CR).
Cut'n'pasting several hundred files into that homepage would not be very convenient :)

i have downloaded backtrack 4 iso from http://www.backtrack-linux.org/downloads/

it have Description:
Name:: bt4-final.iso
Size: 1570 MB
MD5: af139d2a085978618dc53cabc67b9269as

but when i check iso file it have a md5sum text file it contain

I do not under stand any thing ?

so i check in net to have suggestion i find i can check it buy using software so i downloaded one MD5 SUM CHECK VERIFIER when i add that file to verify i get this 529f5d329de6d66975f627dc87030130
this value is not same as it given in site.

can any one help with full detail i will be very grate--full

note:
in the command the file extension (".md5")should read as the file extension of the download; e.g. (".iso")for an iso CD

+1 on the FCIV. I want to comment because this came up just recently and a lot of the google results for when I searched this issue led to a lot of mention of various third party tools, guessing because at the time that is all that was available.

MS themselves have developed an "unsupported" tool FCIV and this is what I'd recommend you use, especially if you're a linux/unix guy and used to command line md5 checking
