Thanks for the info. I submitted a ticket.
Guys - it's a brute force tool. Which is utterly useless if you have a secure password. Will take years to figure it out.
The only reason I'm asking for this tool is Armory does not have an RPC interface or anything similar - if this were my bitcoin-qt wallet for which I effed up the password, I'd simply just brute force against the RPC with a perl script. But since it's Armory, and I need to manually type in all my password guesses, which would take forEVER, I was looking for electronic assistance. Which, thankfully, Armory has.
Unfortunately I havent heard back yet. It's the weekend. I hope I'm not waiting til Monday.

As for how you validate it recreated the password - you use it. If it works, it did it right. If it does't, it didn't

How does the Armory client know you typed in the right password?
