"So here's where the fun comes in.  My colleague (Tom St. Denis) and I have
developed a highly optimized prototype client to find collisions in MD5."

"All functions with a finite number of outputs will fall into a cycle if you
do this:

x = <initial value>
loop {
   x = f( x );

Simply replace 'f(x)' with the MD5 hash function and we have what is call a
random walk using MD5."
