well, i almost do it. i installed a fresh copy of backtrack 5r2 x64 and successfully run NewMultiforcer, with both ati hd5850 (2.12 B/s) and Nvidia 8600GT (80.00 M/s), with parameters --bfi_int and --nocpu. only i get errors if i try lenght higher than 9 (even if i think my whole life wouldn't be sufficient to wait for one hash to be recovered...)
can i use precompiled rainbow tables (the one md5_mixalpha-numeric-space#1-8_60000: 380 GB taken from freerainbowtables.com)? what differences between New_Multiforce and Cryptohaze tools?
