My mom has her bitcoins in an encrypted wallet. She put them in there over a year ago, and she made a strong password that is 22 digits long.

However when trying to move them to cold storage for her, we've realised we can't decipher what she wrote down (in plaintext by hand).

Some of the digits could be a 1 or a lower case L or an upper case I for example.

Is there software where I can type in all the digits I know and let the software try the remaining digits? There would be no more than about 10,000 things it could be. We know for certain what at least 18 of the digits are. But too many are ambiguous for us to try them all manually.

Thanks in advance.

There is some advice and some scripts here:

Of course you should be very careful to read the code before you run it on your system.

thank you very much.

If possible I would advise you to run it on your computer disconnected from the internet just to be safe. And I it works extract the private keys and use them to transfer for coins to another wallet you control. That would be best unless you're absolutely sure you understand every line of code and compile it yourself.

If you know which 4 to change then it should be pretty fast to crack it.  Those scripts should be all you need.

So far I have tried 64 different passwords manually. None have worked so I'm obviously still getting something wrong.

That link you sent me looks excellent, but I lack the necessary knowledge to run the scripts.

Sent the guys in that thread private messages offering money to sort it out.

$100 bucks in BTC to anyone that sorts it!

(I see from the other thread that there is a way -involving salt- that allows you to crack the password without being able to steal the coins).

I'm not going to risk getting called a scammer over 100 bucks. The wallet contains 22 btc, so it's not a huge % to pay out, and realistic for me to do.

Thanks all

1LG8EFSBMAowMtmHYzH2s5VEa2FV1Csphm is the address. Obviously, I can't sign anything as I don't know the password :s

It's not too difficult to run the scripts.  I'm not sure which salt method you're talking about though.  Beware of anyone who wants you to send your wallet to them.

1)
xxxxx 1 xxxxx 1 xxxxx 1 xxxxx 1 xxxxx   (one-one-one-one)
xxxxx 1 xxxxx 1 xxxxx 1 xxxxx l xxxxx    (one-one-one-L)
xxxxx 1 xxxxx 1 xxxxx 1 xxxxx l xxxxx    (one-one-one-I)

2)
xxxxx 1 xxxxx 1 xxxxx L xxxxx 1 xxxxx   (one-one-L-one)
xxxxx 1 xxxxx 1 xxxxx L xxxxx l xxxxx    (one-one-L-L)
xxxxx 1 xxxxx 1 xxxxx L xxxxx l xxxxx    (one-one-L-I)

and so on.
Is it password for online wallet or is it password for your local file wallet.dat?
In second case you can put your password here (because nobody [?] has this file to decrypt)

if you're talking about the script in page 2, the easiest way to run it would be to create a ubuntu vm in vmware, configure the script to connect to a bitcoind instance in the host operating system, and run the script in the guest operating system.

"easiest"

Well thanks for making me feel even less techy than I already do.

I have ubuntu installed in parallels already, along with bitcoind and the wallet-qt (but version 0.9.0. I can't work out how to install 0.9.1, because the ppa:bitcoin/bitcoin thing is running behind, and I don't know how to build it from the download on bitcoin.org.)

I also don't know how to import the wallet.dat into the ubuntu wallet.

If someone helps me do all this, I'm sure I'll have more questions afterwards.

Where is my knight in shining armour then?

you don't need to have bitcoin installed on the guest machine. you can run bitcoin on the host machine, then get the script in the guest machine to connect to the bitcoin instance via RPC.

You shouldn't need to use 0.91. You can import the wallet.dat in a number of ways:

Copy it to a USB drive on the host, then connect the drive to the guest
Create a shared drive (I've never used parallels before so I don't know what this involves)
Scp it over
Put it on dropbox
Email it to yourself

Obviously some are more / less secure and easy/ more difficult (scp is probably the best I think)

thanks for the help guise, got this sorted in the end!

My friend wrote a scrypt and tried 2 million passwords.

I'm gonna advise him to start doing this professionally, it's gonna be needed so much.

2 million passwords in one scrypt ..that is perfect he should take your advise seriously.i am glad to solve it.

This scrypt would have carried on forever, it just stopped at under 2 million because it found the password.

also double check obvious numbers that you are sure of (18 of them) and maybe you will find another posible gap there.
