yes, i saw some code you describe on masmforum which uses MMX, it was
extremely fast in tests..The method you describe is something like 6x
faster using 32-bit code than normal hashing, and a staggering 300x
faster using CORE 2 SSE4 optimised assembly!!

i've seen the 32-bit code implemented in a commercial password cracker
i won't mention.
now a days, the SHA1 hash is more popular though, but still an
interesting attack you describe which could be applied to other hash
algorithms.
