>From what that page says, it looks like thta sha1 is not recommended for actual use (although they don't test with gcc 4.x). I've come across the gnulib sha1 routine, which is adequately-licensed, and is fast enough to give us a 10% speedup in my obliterate test (beyond which we probably hit diminishing returns--we're probably no longer spending much time in sha1 at all). -- David Roundy Department of Physics Oregon State University _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
