winMD5Sum.exe md5 hashes

I downloaded the installers from http://www.nullriver.com/products and https://portableapps.com/apps/utilities/winmd5sum_portable, I exacted from each one the winMD5Sum.exe and I calculated the md5 hashes.

nullriver.com hash : 0822ec2ba98d291e5bfc836bc3686096
portableapps.com hash : a869749de98e20880c525dab5b8dea7c

I also opened them with 7-Zip and their contents are different.

Why the files are different?

different md5

Our installer is different from nullriver's, thats why. Our includes some portableapps.com-specific files like readmes, help.html or icons and text files so it displays nicer in the portableapps.com Platform.

You didn't understand

You didn't understand. I mean the winMD5Sum.exe files, which I exacted from installers. They should be the same file.

one possible explanation, the

one possible explanation, the one we carry could be an outdated version than that of nullriver's released copy. not saying that is the explanation but only John can answer that one.

Compression?

Ours might be compressed, resulting in a different hash. As for contents being different, I don't know what that might be.

  1. You have your Hashes backwards, the PortableApps.com release's MD5 Hash is 0822ec2ba98d291e5bfc836bc3686096, and the NullRiver release's MD5 Hash is a869749de98e20880c525dab5b8dea7c
  2. This also explains the difference in contents when viewed as an archive by software such as 7-Zip:
    • NullRiver's release contains the following:
      These are resources the program needs to access while running.

      • .rsrc [Directory]
      • .text
      • .rdata
      • .data
    • PortableApps.com's release contains the following:
      These are the same resources, compressed (where feasible) to occupy less space, but still be accessible to the program while running.

      • .rsrc [Directory]
      • UPX0
      • UPX1
  3. Nullrivers release is 81,920 bytes, and PortableApps.com's release is 51,200 bytes, and while this is only a difference of 30,720 bytes, it doesn't affect the operation of the program, and every write cycle on a flash drive is one closer to failure, so why not.
