Now that you have the official checksum numbers on your hard-drive you can check the ISO(s) that you have against those checksums. If you do this for both files you will now have two text files on your hard-drive titled "md5sum.txt" and "sha256sum.txt" (If your browser doesn't have a right-click and download the text files function then just left-click on the two links and copy and paste the checksums hash information from the webpage into a text editor of your choice - remember to save them as "md5sum.txt" and "sha256sum.txt".) Follow the same procedure for the link titled sha256sum.txt if you want to check the ISO against a SHA256 hash number. Once you are the correct webpage for the Mint version that you want to check right-click on the link titled md5sum.txt and select " Save Link As." and save a copy of the text file to your hard-drive. (For the purposes of this tutorial I will assume that you want to check an ISO for Mint version 17.3.) Step 1 - Get a Copy of the Official Checksums File(s)įor checking the MD5 and/or SHA256 of an ISO go here and get a copy of the checksums files for the version of Mint that you want to check: Tip: just click on the link that is the version number you want to check. ![]() But in the longer run I would guess Mint will abandon MD5 sums and transfer to SHA256 (or higher) - extra security at no extra price - go for it. That said, for most purposes MD5 is okay because it's reasonably secure anyway. ![]() ![]() What is the difference regarding checking via MD5 or SHA256? SHA256 is a much more secure check than an MD5 check. The guide below is my newbie way of trying to explain how to check Linux Mint ISO's using MD5 and SHA256 checksums in a Linux or Microsoft Windows system.
