Fast MD4/MD5 Hash Cracker

    Sorry about the post i made yesterday (this is edit of course)

    I removed the link because the code wasn't working properly.

    There were 2 very silly errors in it.
    1 to check the second hash, and 1 to fill the second password buffer
    which led to me thinking that it was 10 times faster.
    Not much testing was done with it, wrote it in a few hours, so excuse me.

    It seemed faster after i fixed it by about 10% but it wasn't anything to brag about...its actually same speed as something i wrote 2 years ago.

    This morning i used the md4_mmx routine for writing core1.c from mdcrack and it seemed to speedup by about 33%

    Like, it took 6 seconds to find "ZZZZ" with the app i wrote and 9 using mdcrack.
    After testing "abcde" which only took 7 seconds with my app, but 45 with mdcrack i knew something was wrong.
    Furthermore, it took my own app 7 minutes to find "ZoRce" whereas it took
    45 seconds with mdcrack.

    The reason for this is the string creation routines differ, so i'm not gonna say any more about it without more testing/coding.

    I will just say, I think the mmx routine would still be around 33% give or take, faster than using 32-Bit core1.c providing i switch to the same string/password creation routine as mdcrack.

    i'm not gonna bother posting any code right now, as i feel a like a bit of fool today after that post yesterday.
