How to verify an app file using the provided MD5 Hash key?

The easiest way is to download a checksum checker such as:

I know the next question! If you down load a checksum checker how do you then check the checksum of that download?

Well, if you must, try Microsoft's own help page here:

Have fun.

I use, for various times, either WinMD5sum or DownThemAll. You can use Rapid CRC as well, but it doesn't compare, it only calculates the MD5. I tend to use it when building app updates, so I can calculate multiple MD5's at once.

WinMD5sum, on the other hand, will compare the MD5 for the file you choose. You should be choosing the *.paf.exe file for whichever app you've downloaded.

Alternatively, you can use the DownThemAll Firefox extension, which allows you to enter the MD5 prior to downloading the app, and it'll confirm it when the download is complete.

Hello Laurent,

every download file from here (at least the official ones, but most development tests, too) has it's md5-hash noted somewhere on its download page. Rapid CRC Unicode 0.3.15 portable (RapidCRCUnicodePortable_0.3.15_English.paf.exe) has f98f91232370b2abb1d1739fde392916 for instance. You find that at the download details on the bottom of the specific page.

The easiest checker is the one mjashby mentioned. But Rapid CRC Unicode can also do the trick (you have to switch on md5 in options).

You just need to check the paf.exe file. If it's checksum is correct, the containing files will also be. No way to change the internals of an archive without changing its md5 checksum.
