help with hashcat 5.1.0 and itunes backup recovery

[tedz]

hi atom...

thanks for your help...

do you any suggestions on hash modes that i could try...

apple replaced my phone with a new unit, 
created an itunes backup of my old phone to my laptop in store,
kept my old phone,  and handed me the new phone and sent me on my way...
they erase the old phone immediately for security reasons/protocol...

so when i get around to trying to restore the backup to the new phone,
itunes asks for a password to unlock the backup,  doh...

i'm not sure that i did encrypt the backup that i did 6 months prior on an old dell laptop,
although there is a padlock next to both backup folders,  1 current laptop and 1 older laptop...

i have tried to unlock the itunes backup restore phone function, 
with passwords that i usually use for various accounts,  with no success...

i would think that i would have used the phone unlock code and maybe something added to it...

so i am unsure  how,  and if i  should try to get  hashcat set up to use my unlock code plus some extras...

is there a section in the help pages that i can learn how to do that...

thanks for your help,
ted...
