I guess it comes down to a couple of reasons:
1) If I distribute the tool (open source-wise), then unscrupulous persons can use it. In fact I have already been approached by someone wanting to buy my software stack, but I turned them down outright, since it was probably a botnet owner or similar... I didn't want to be sullied by the bad guys.
2) If I distribute the tool, then I have little chance of making any money. Currently I am working on several wallets with substantial 'rewards'. (as well as some with little or no reward, I might point out)

Also, (as pointed out later in this thread), quite a few of the specific wallets that I've worked on do indeed require tweaks to the algorithms... no matter how generic you make them, someone always has another bit of remembered logic up their sleeve... like "wordnumberwordnumber where I'm pretty sure that the numbers were the reverse of each other's digits", etc, etc

Maybe when/if I get tired of bitcoins and wallet decryption stuff, then I will open-source it.

Do you have any vouches from users who had their wallet recovered?

It is interesting that most users prefer to remain quiet. (perhaps a degree of embarassment).

Currently I am busy with attempts on multiple wallets. (both bitcoin/litecoin based and blockchain.info based)

The majority of wallets decryptions that I've attempted have been unsuccessful, but I have had a number of notable successes. I might prod those (successful) wallet users, and see if they will put a message up here about their experiences.

Cheers

Hi
To put your mind at ease, no, I haven't identified any encryption weaknesses or shortcuts to the decryption mechanism in the bitcoin, litecoin or blockchain wallets.

Development on the toolset continues. It is surprising how many different types of {x} there are amongst people's "I thought I knew my passphrase but it doesn't work, and it might be because {x}"
 

Regards.

Wallet recovery is definitely possible to do without scamming. I would not be so quick as to yell scam, but I would be sure not to send my whole wallet to just anyone who requests it!

It reminds me a lot of hired vanity address generators. It does not seem smart to let someone generate a whole private key for you, however https://bitcoinvanity.appspot.com/ seems to have a good way to do this. If you generate your own part-private (or split-private) key then you would be fine.

I do not see why a system built on no trust needed would need to rely on so much trust. If I don't understand something, I may risk some money in attempts of understanding if it's legit and logical, but I don't risk more than I'd be willing to lose.

We should not forget that Pirateat40 had the best OTC reputation for some time

Looks like I was having one of my grandpa moments. I thought I had read that trust would build over time and this service would be accepted, which is why my response was saying that services should not rely on trust but comprehension of the underlying procedures. Sorry for any misunderstanding.

What this guy has to offer is essentially a lot of computing power that can be rented for the time needed to brute-force a mistyped password. It is pretty awesome and I would definitely recommend anyone who needs a service like this to read into it.

ok, we are in touch. Dave

i was so going to jump on your service, till you mentioned that you cant get 15+ lettered passwords, its a shame, i blame hardware for that one, not you

it is a blockchain.info wallet.aes.json, i have no re-callable memory of what it was, i probably used lastpass password generator (nothing in its history though :/)

the one thing i never got out of this, was your cost of service, or is it what ever it is worth to the person?

i'll continue scouting all my HDDs for any random file with the password or mnemonic stored in it (im so good like that, texting up my password, leaving them laying around.. like keys to my cars left laying around in the pub)

Anywho, scam yodellers still have no proof that you are scamming, and you haven't been shut down and out yet, so you're out there doing good then
