how to crack MD5 middle with MASK attacking mode? - gongtudouxiafan - 12-10-2014
Hi Folks,
I'm cracking a MD5-middle hash of password "EfEVp5953R" using below command(MASK mode).
./hashcat-cli64.bin -a 3 -m 5100 hashes/1.txt EfEVp5953R
But it seems "M 5100" only works for "left half" not work for "middle half" and "last half".
More specific, if I put "40030674df2ef9d7" into hashes/1.txt, the password can be recovered; if I put "b1db24f7416abeee" or "df2ef9d7b1db24f7", it can not recovered.
Any switch/option to enable the middle/right MD5?
Thank you very much!
Jun
P.S.
MD5{EfEVp5953R}=40030674df2ef9d7b1db24f7416abeee

what you are looking to do is not supported by hashcat

From below post, it seems it was implemented?
https://hashcat.net/trac/ticket/89
If it's not supported by hashcat, do you know which tool support it? will oclHashcat do? Thanks.

hm didn't know atom implemented that, or how exactly he did implement it. maybe he can chime in on exactly how it works.

it works fine on oclHashcat:
