    Linux noob alert: I'm sure there are other variations of this, but I found a little program called DigestIT 2004. Once installed, just right click on the .iso image you want to burn to a disk, and copy the md5 hash into the box, and click verify. Anyone else use this?
  2. No.

    To compute the md5hash you need to use a md5hash generator. On linux try the md5sum command . For windows get the equivalent md5sum.exe.

    Then compare the 128bit hash to the hash provided by the "source" site or whatever or the authenicator.

    Nope.. :)

    I rarely check md5's. Generally I've found as long as I burn slow(4x), and use quality media, my ISO's work no prob. Its been a long time since I've had a bad burn of an ISO.

    Thanks guys. I think I misspoke. I downloaded some linux distros on my XP machine. digestIT verified the md5 on the .iso image while it was sitting on the XP desktop, before I burned to disc.

    +1 on the slow burn. I've got a few extra coasters now.
  5. so how does it verify the ISO image md5 checksum? Does it go back to the location that create the ISO image and download the md5checksum ? or does it require both the iso image and checksum to be download at the same time for comparison?

    Either way, the md5sum command will quickly compute the md5 hash and then you can compare it to the "original".

    FWIW, I have a perl script that does the computation for md5,sha1,haval and ripemd5 hash quickly and easily so you can compare the resulting hash to the original with

    No, I either download the md5 or copy it from the mirror and paste it into the program window. Prolly better ways of doing it, but I'm not very techy.
  7. from what I found out and do, if I don't think I need to worried about it , then I typically never validate the md5 unless it's security related. Same with using PGP on email.
