MD5 in 64-Bit OS?

We all familiar with MD5 hashing. But let's see the screenshot below.

MD5 Hashing and File Size

You see, two files with different file sizes are having the same MD5 hash value (8ae6dd9a6d246004da047f704f0cc487). Is it MD5 hash coalition? No, once we use the right tool, md5deep64, we get the right result.

For an explanation of WOW64, see Microsoft documentation on Wow64 and some implementation details.

So, let's make sure you have the right tools for your new 64-bit OS today.
