BRUTE FORCE PASSPHRASE RECOVERY?? COLX wallet.dat

Feeling pretty silly right now..  I've had a 'copy/paste' issue with the pass phrase which I've encrypted my COLX wallet with,  I think rather than the actual passphrase I've probably pasted a file system path as the phrase instead.

I need to figure out a way I can try and make brute force attempts to unlock the wallet to recover the coins.

Is anyone is able to suggest an approach for doing this?  or point me in the direction of a tutorial or something? 

I have tried to research this,  and I've found a few references to brute forcing qt wallets - but I'm unsure of the specifics of these and whether I can simply use that approach for the colx wallet.. any guidance would be most appreciated..
