The code uses byte strings. There is a confusing call to a
`string->bytes' function in 

   (define (md5-computation str)
     .... (string->bytes str) ....)

But `string->bytes' is actually bound to `bytes->list' earlier in the
module. (This was probably sloppy porting on my part.)

So the MzLib "md5.ss" code really does work on byte strings, not
character strings.
