Brute Force – Steganos Locknote

Good day all,

I’m hoping someone can help me find a hash inside a Steganos Locknote file. I’m a network engineer / programmer by career so I’m a bit out of my forte, but I’m trying to help a friend recover data from the Locknote file that his father left behind after passing away.

I’ve had a look at some of the available tools, John the Ripper, Cain and Able, and Hashcat. They all seem to require a hash (of course) to target for a brute force attack. Is there a technique I could look into that would identify the hash? The reason I ask is the only other way I can see to brute force would be to execute the file and type into the dialog box.

I realize the chances of recovering the data are slim as the gentleman who left the file behind was in fact a clever person, and I suspect he knew to use a long password. Regardless I would like to run some attacks against the file, so I can say I took a good crack at it… pun intended.

Thanks for reading.

Cheers

Edit: Steganos Locknote is an executable that encrypts data within itself using a master password.
