Permutation attack with mask - sanshinron - 11-28-2012

Hey guys,
I have a SHA256 hash in a format of $username.$password. I know the username. I also have a wordlist file and I'd like to use it against this hash. I'll be using nvidia gtx570 with cuda.
How can I setup oclHashcat-plus so that it only searches for the $password part of the hash and ignores the username in the beggining?

you can add a rule to always append the username. ./olchhc [options...] -r rules.rule -r addusername.rule

Good answer but it's prepend, not append. If you make rule don't forget to invert your user name. For example, if you want to prepend the username Bill, the rule is ^l^l^i^B.
