begood Posted June 10, 2009 Report Posted June 10, 2009 As promised I hereby present my MD5 password brute forcer, called EmDebr. I used reversing to speed things up, see my previous blog for more information about reversing.I also gave interlacing SSE2 a try (did that after I posted my previous blog and came up with a speed improvement of about 40%. So on my own system (3.2Ghz quadcore) I got like 77 Mhashes/s before interlacing, with the current version I get around 100 Mhashes/s. Interlacing SSE2 is not my own idea and can be done (a lot) better then what I came up with. EmDebr is in this way still by far not the fastest SSE2 optimized MD5 password brute forcer around, as far as I know that's still BarsWF. As far as I know EmDebr is now the fastest open source one though I hope this helps others to understand reversing and maybe you can use my code to write a better/faster open source cracker. Feel free to leave a comment or to post some improvements! Quote
