Re: john the ripper

The Cisco MD5 hash is a specialized and salted hash. It uses additional 1000 rounds in the algorithm to slow down password crackers like john the ripper, Cain & Abel and 'Too many secrets' that are all able to crack the cisco MD5 hash. That's the reason why john seems to be slow. The faster your system the faster you will crack the password, but if the password is a strong and long one it can take months, so don't worry about it. Looks like the password is a better one than usual ;-).

Hi all

I am tryning to crack cisco md5 password.
Currently I am using a Athlon XP2500barton at 2300mhz, after 17days john continue to crack at 3800c/s (it started at 4500c/s). I am asking myself and all of you what is the best system (hardware) to crack md5 password.
I am thinking that the best way Is the powerfull (mhz) i386 in commerce.
I've tried OpenMosix with 4 p500 nodes with john and cisilia, but without lucky results.
The sun 280 (dual 64bits cpu at 900mhz) go to a poor 900c/s

which is you reference system to use john on md5 password ?

Giacomo
