Brute force a password using only given letters/phrases?

Is this possible?
Basically, somehow, I've forgotten my litecoin wallet password and need to access it. Which doesn't make sense to me because I never use passwords I can't remember (i.e. all of my passwords are derived from the same phrases) and yet somehow I set my litecoin wallet to something different, or slightly different enough for me to not get back inside.
I was wondering if theres something out there where its possible for me to bruteforce the password, but only use phrases/letters I give it (the phrases/letters I always use when I make a password) in determining what the password is, so it at least wouldn't take 12 decades to complete (hopefully)?
It's an encryption password so captcha isn't an issue.
Of course the software exist..
Defcon is this August, maybe ask around
:wink:
How many combinations are you thinking? You should be able to generate a word list to your specifications then brute force with that.
EDIT: I've done something similar; I knew a password was a combination of 3 shorter passwords, but couldn't remember what order. I made a python script that generated a list of all the combinations of the shorter passwords and was able to brute force it in a few minutes.
Don't know off the top of my head but I usually use 2 or 3 words in my passwords that I keep consistent between all passwords, occasionally omitting a letter or adding a number. Always at least more than 6 characters and less than 14..which is why I always remember my passwords because there are only permutations of that. But none of the stuff I usually use is working, which makes me think I accidently threw in a curveball somewhere.

Here's a script in this thread someone made up that specifically works for bitcoin wallets (I'm pretty sure litecoin wallets are basically the same as far as encryption goes), but I can't for the life of me figure out how to use this script myself.
Anymore help with this?
what script, I don't see it linked in the thread
you can just write one yourself

seems pretty straightforward, did you read the readme?

that script won't do what you want though
Ahhh wait a second there was a powershell script posted, I guess I need to download powershell to run it
All the other scripts were some kind of bitcoind ruby mixture and I didn't really understand what they were talking about.
Why wouldn't it do what I want?
the script in the thread makes permutations of a single password you enter (depending on what characters you want to include) it doesn't make combinations of words that you give it
Even the powershell one on page 7 or so?
It gives me an area to put a blocks of words that it'll try to make the password with i.e. me putting "puppy","dog" it'll try and put those together in combonations
