MD5 - A Brief Explanation
A simple explanation is that MD5 (Message-Digest algorithm 5) can be used as a way of checking that a computer file has not been maliciously or accidentally altered. A bit like our fingerprints are unique to us and can be used to identify us, computer files can also be examined to produce a unique identification in the form of a block of 32 letters and numbers. Using a computer program containing the MD5 creation code (called an algorithm), it can generate this block for each computer file that is examined. This block of 32 letters and numbers is called a hash (also termed Message Digest).
Before I lose the technically faint hearted altogether, I will stop there and explain a practical use for MD5 and how it can possibly help you. My web site has several software programs available for download and it also has published MD5 hashes for that software. Many other websites now also include this information. But having downloaded the software, how can you check it against the published MD5 hash? This gave me the idea for this project. A quick and simple way of checking a file's MD5 hash against the published MD5 hash.
MD5 Checker is simple and easy to use. Start MD5 Checker and select the file that you want to check. The chosen file's MD5 hash is automatically generated and displayed. Now obtain the published MD5 hash for that file. Copy the published MD5 hash onto the Clipboard and click on the MD5 Check button. The published hash is automatically pasted in from the Clipboard and a check made. The result of the check is then displayed. You can try this out with md5checker.zip and MD5 Checker.exe
You may have noticed that an increasing number of websites that have software available for download also show something like [filename] MD5: C7B4EFC3A441400E7946CAEB548BB7E2. I have included such information for all of the software on my website. It is not always necessary to check downloaded files, but this utility may come in handy when you do.
I have noted that some websites link to the previously named download file md5check.zip. I have uploaded a copy of the zip file and named it md5check.zip so that the links will still work. The MD5 hash is the same as both files are identical, only the file name has been changed.
