litecoin wallet

Hi,

i just transferred litecoins to my litecoin-qt wallet (that i've never used before until now). afterwards i was supposed to transfer some of it to another destination and i froze: it asked me for passphrase.

i instantly remembered that i had set a passphrase some months ago to try out the encryption feature. it was a really simple password, probably somewhere around 3-7 chars and probably an english word.

is it possible to use hashcat (cpu or gpu version) to find my password?
