Sha1(user:pass) decryption - deepsylol - 01-07-2013

Hello guys.
I just found out how awesome hashcat is and now I'm trying to figure out how to decrypt these passwords:

The passwords are generated this way:
Code:
$hash = sha1(strtoupper($user).':'.strtoupper($pass));

I know the hashes and the user name and I'm looking for the password.
Can anyone help me to configure hashcat, so I can decode these passwords?
Thanks.

Cool, now take a week to read the forum rules.

What about a combinator?

./oclHashcat-plus64.bin -m{number for sha1} -a 6 --outfile=outfile /hashfile /namelist ?l?l?l?l?l?l // or whatever charset you want to define

This mode is nearly supported. Try with -m 121.

Make sure your attack mode will only product upper-case passwords.
