Is there an official page for MD5SUM. I have noticed several utilities on the web and a program called MD5.EXE gives me a different result from what the Redhat page says I should get? I did find a MD5SUM.EXE command line utility that gave the right result but it took several minutes to calculate it. Does it matter that I am on a Windows System as opposed to a Linux system when using a utility to calculate the MD5SUM value?
