Squeak has DSA in the image.  I dunno why DSA was chosen over MD5 -- if
the uses of DSA can transfer over, still, then it would be nice to
switch. 

Otherwise, MD5 is certainly widely used, so having it handy would be
nice.  Modules are gonna be here any time, now, anyway, right?  So the
bloat won't hurt as much.
