[edit] File integrity

To check the integrity of downloaded files, one can use an MD5 hash to calculate the MD5sum of the downloaded file and compare it with a known good sum. Below is a table of known good MD5sums (the list will be fleshed out shortly):

There are many tools that can calculate an MD5sum, for reference one can use the freely available MD5-Checksum by Nero because it lets you specify a known good MD5sum and it automatically compares it with the MD5sum calculated from your chosen file.

[edit] Verification process

Step 0. Copy a MD5sum into the clipboard by selecting a MD5sum from above for the wanted file, and pressing CTRL-C.

Step 1. Start the MD5-Checksum program and press PASTE, the sum will be written in the program.

Step 2. Press BROWSE and choose the wanted file.

Step 3. After you choose the file the program will calculate the MD5sum, be patient, this can take a bit depending on the speed of your hard drive and processor.

MD5sum correct

Step 4. If the MD5sum is the same you will get a message saying "MD5 Verification succeed!".

Step 5. After pressing OK the MD5sum will be shown in a green color, now you can paste another MD5sum and check another file.

MD5sum Incorrect

Step 6. If the MD5sum is not the same as the correct one, or if you accidentally modified the written MD5sum an error message will appear stating "MD5 Verification Failed!" and some directions are given, if this happens to you then it means that the file needs to be downloaded again.

Step 7. After pressing OK the MD5sum will be shown in a red color.
