Another thing is that they should create an opensource script that grabs the portions from the wallet that they need for a safe decryption. Because the script will be opensource people will have confidence that it is doing exactly what it is supposed to do and not anything else.

It really is easy enough to follow the instructions manually: pywallet --dumpwallet, edit human-readable dumpfile (remove all addresses except 2)

I'm currently working on several wallet decryptions.

Cool. Do they look like they have a chance of success, i.e. did the users provide helpful enough info?
Hi
Still working on the wallets. One of the 'customers' has some reasonable idea of the password, but also a big list of possible variations and alternatives. Some of those alternatives have required me to make some enhancements to the logic in the service to cater for that type of permutation.
So... no luck yet, but continuing to work on them.

I see that the 1 BTC is still secure. (I was a tad worried that I might have overlooked some aspect of the wallet format that might have lead to a vulnerability to the third-party trustlessness that I explained. Fortunately, it seems like it is all secure Smiley )
Thanks for your suggestion and help on this 'proving not a scam' process, Molecular, it has been really helpful.

Cheers
Dave

Hi Erpalum.
( I assume that you are the person who sent me information today using a completely different email name ? )
I shall try to recover your wallet, but your information on the remembered password is a bit skimpy, so we'll have to see...

Dave

Tell you what...  If (and it is a fairly bit if in this case), I make any money from helping Erpalum, I will send you 10%.

Oh, really?


oh, i will add one more thing, if you decide against using my help, you might try the user "walletrecoveryservices" or something to that effect. he claims to have invented a program that can strip the public key out of wallet.dat files and use it to bruteforce the account with no possibility of stealing the funds. to my knowledge he hasn't proven that it works or is real, but he's made the claim. i'm not sure what his rates are either. if you do choose to use the walletrecovery guy, please be aware his account isn't very old and he could very well be a scammer.

Scammer Fails So Hard

Ok, let's harden the assumption he can't scam us.


I accept your challenge, Molecular.!!!
I have transferred 1.00 BTC to that address, 19xTYJg3i1YuoHtYqtNhXcer65K9wZ1n4b
You have published the details of that wallet above, so everyone reading this now knows the same details as the walletrecoveryservices.com website is asking for when it tries to decode a wallet.
There is 1.00 BTC in that wallet.
I can't steal it, and I do not believe that anyone else can either. Prove me wrong, skeptics!
If you think that the concept behind the wallet password recovery service is flawed, here is your chance to prove it, and earn some cash.

Here is the record of the 1.00BTC transaction: https://blockchain.info/address/19xTYJg3i1YuoHtYqtNhXcer65K9wZ1n4b

I'm trusting Molecular to return my 1 BTC at the end of this exercise... sometimes you have to show some trust to earn some trust... Smiley


Cool.

Money has arrived:




ok, so a week has passed and walletrecoveryservices PMed me wanting his 1 BTC back, so I sent it to him.



notice how someone used the 1ErroNQ... address? It was in the wallet dump I published, so anyone might've used it.

not so the 19xTYJg... address. The bitcoin seems to have been secure there despite me having published the wallet (omitting that address, of course) and the password.

Ergo, I'm quite sure walletrecoveryservices has no way to steal your money if you send him your wallet dump after removing addresses with money on them.

That was me (notice the address and public message). I just wanted to see how difficult it would be to extract the private key from the wallet fragment given the password (answer: fairly easy, just a messy hack of the the pywallet code).

As for the rest of the wallet. Its completely secure. Your only option is to brute force it, which is an impossible solution (the numbers are just way too large to be feasible, it would take until the end of eternity, then start again for an eternity of eternities kind of unfeasible).

Anyway the challenge was fun, I learned something about wallets and the various encryptions used  Cheesy

I can confirm that Molecular has sent me back my 1BTC.
Thank-you very much, Molecular, for both your honesty (in returning my 1BTC), and your willingness to get to the bottom of whether the walletrecoveryservices.com service was trying to scam anyone.

Dave

It would be interesting if you could create a "pool" of people's machines to crack (err... recover) wallets, and distribute the fee to them based on how much work they did. I imagine you could do something similar to mining pools.

or similar to vanitygen-pool. cool idea.

I'm not sure its feasable. You'd have to find a way to divide up the search space and somehow make provable some subspace has been searched. This is different from vanitygen or mining where there are many solutions, not just one.

Yes, I've thought a bit about doing this (splitting up the search space and making a public API to access it).
Perhaps in the future.
However, for now, I can just run up multiple amazon instances to do the same thing.
p.s. In response to demand, I now have added the ability to walletrecoveryservices.com to brute force crack the blockchain.info wallet format too. If you have a wallet.aes.json file backup (for your mobile or online account), then I can help you recover your password if you've forgotten it.

Dave

Does that blockchain.info wallet format also allow removing the keys that have money on them in the same way as the bitcoind one?

The blockchain.info wallet backup format contains a sharedKey, various options, and (I believe) just the last used address. You can't separate the information in the same way as the wallet.dat format allows.
 So no, if there are bitcoins attached to that particular address, then they are potentially thievable. However if the bitcoins are on other addresses, then I don't believe that those addresses are disclosed in the backup. (afaik)

The temperance and perspicuity you display is admirable.
The fact that such an offering could be done by an unscrupulous scammer does not make you one.
Holding the tool vs distributing it is an interesting choice.  Would you care to comment on that?

I can state with some confidence this is no scan. He has some cracking power available, so it males sense to offer as service.
