MD5 Hash A String
MD5 is a one way encryption or hash of the input, and is commonly used to check the integrity of files.
With the almost never ending amounts of passwords and user IDs required to use websites, it's extremely dangerous ot use one password for all sites so it can be useful to use a phrase for a web site and then get the hash to be used as the password. Eg, "myname amazon.co.uk" becomes "c64cee32" so one could use that as a password that's too hard to guess but easy for one to lookup again.
