Just to go
back to
the
original
idea,
briefly: I
tried this
with
Mathematica
and MD5 a
few months
back.
Suffice it
to say
that "a
long
pause" is
an
understatement.
And all I
asked it
to do was
a
simplification,
nothing
fancy, of
a single
step. :-)

Mathematica
is perhaps
not best
suited,
because it
doesn't
understand
bitwise
operations.
OTOH, you
pretty
much have
to asssign
a symbol
to each
bit, so
perhaps
that
doesn't
matter.

It seemed
to me that
a
special-purpose
solver
with a
more
limited
domain
would
probably
go faster,
but I have
no idea if
that would
be fast
enough. I
haven't
had time
to play
with it
yet.

Cheers,

Ben.
