Another Google search turned up the fact that this code (actually some other
code that is very similar to this) would omit leading zeroes when it prints the
md5 hash. That information might also be of some use to anyone thinking of
using the code. Some strings that should produce a hash with a leading zero
are: "minute", "hash", "a" and "shuttle". Thanks for posting the code. It gives
me something a lot more useful than a "hello world" program to toy around with
java with.
