Thanks you for your replies guys. I just got a chance to tweak with BTCrecover and the tokens + typos maps and this could well be the wat to go, since I know what the password should have been.

I will give it a good shot and if that works I'm planning to write a tutorial for the ones who endup in my situation. That could be helpful as the UX isn't that easy to deal with with those powerful tools.

My only concern now is the poor way btcrecover performs with OpenCL on nVidia solutions.

How many hashes per second do you get?

Hey guys.

I recently did something stupid with my fat chubby fingers. I have a small BTC wallet with not that much in it but still, I wanted to encrypt it as I feel safer that way.

And so I did. With my usual password.

But it seems that I made a mistake (twice !) by typing it and now I'm looking to a way to configure the btcrecover token file for making it work when:

1: you know the password
2: but you made a typo, misswrote a part of it, inverted two letter / numbers. This kind of mistake.

If not possible, do you know a GPU accelerated tool that could work that way? I found Bitcoin password recovery tool by Thegrideon Software but I don't know if that's good or not.

This also is an interesting event to be used to learn a bit more. The amount isn't that big, but the challenge is interesting.

Thanks.

Hello,

1. what type of wallet is it, bitcoin core, electrum etc.
2. Download John the ripper lib from Github and use python and correct wallet converter like blockchain2john.py or tools to generate hash
Download link: https://github.com/magnumripper/JohnTheRipper
3. My first choice would be hashcat, as it supports many formats an has great support, download from hashcat.net
or Github: https://github.com/hashcat/hashcat
4. Create a password list, add rules and run overnight, it should find it.

If you need help with John the ripper or Hashcat they have their own boards with support

good luck

Thanks, will give a try to Hashcat too.

@HCP
Yes, that is part what I wanted to ask as well. Maybe OP is using different keyboard languages which changes a few keys around. For example when I type in Croatian the Z and Y are inverted and additional letters are added for ;'# (on the English layout).

@OP
If your password has numbers maybe you turned off Num Lock. Try entering it without the numbers.
Could Caps Lock have been turned on or off when it shouldn't have been?

Just out of curiosity... does your "usual password" contain any special characters like , ' " \ / ? | etc? or perhaps any "non english"-type characters with accents like à á ä ø è ê ç etc?

Yup, BTCrecover should be able to do this just fine, if that's what you're asking. https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#typos

Maybe use something like john the ripper if you don't want to use btcrecover?
They both offer gpu support, no?

so i'm guessing that would be something along the lines of

Code:

--typos  --typos-capslock --typos-swap --typos-repeat --typos-delete --typos-closecase --typos-insert %1,2in

Where --types-insert would insert two or 1 random characters twice into the password (besides the swapping/repeating of characters). Just to give you an idea. Probably not necessarily necessary. You're gonna have to figure out what works for you.
