I guess you are using hashcat? Then indeed the john bitcoin2john.py is needed. If you want to use btcrecover, you can use this script: https://github.com/UwSoftWare/trustless_btc_recovery (btcrecover has its own extract script, but this will also extract the public keys, easier to check the balance before helping your friend)

You can recover you keys on the following way: * Surf to chrome://extensions/ * On top you will see a checkbox 'developer mode', click that. * Then scroll to the Sparecoins extension * There you will see 'background page', click on that. * Now a debug screen will open. There you will have to copy paste the following (change the xxx in your password and press enter): Code: var password = "xxx"; // Load library var scr = document.createElement('script'); scr.setAttribute('src', 'lib/aes.js'); document.head.appendChild(scr) // Opening wallet and read out the addresses var Wallet = SpareCoins.Wallet( SpareCoins.ChromeStorage ); Wallet.loadData(function() { Wallet.getAddresses().forEach(function(address) { if(address.decrypt(Crypto.SHA256(password))) { console.log("public key: "+address.getAddress()+" private key: "+address.getPrivateKey()) } else { console.log("password is wrong"); } }) }) Now it will print all your public address with next to it the private addresses. The private addresses can be used in other Bitcoin wallets. *Updated to make sure the script also decrypts the private keys https://uwsoftware.be/index.php/bitcoin-recovery-service/ 1PMxqTNHyQuZ73Gkg6xVUTggB7Gy5cqwYV

If Dave is to busy, you can also our service https://uwsoftware.be/index.php/bitcoin-recovery-service/. But be advised, only give it to persons you trust! As there are not a lot of trustless mechanism already developed for altcoins. But you only can get help, if you have still a wallet. Because you cannot recover your private key from your public key. But you can recover your encrypted wallet by your password (if you your password is humanly weak)

I've added a poll to this thread. I want to know how many people already lost some Bitcoins. Just as an insight, as only persons who have lost Bitcoins come to my service.

I you feel saver by Dave, you should use his service. I'm not willing to lure his clients away or to compete with him. He has a fantastic service and a fantastic reputation. He already does this for a long time. I'm only starting. But there are some differences: - I'm asking 15% fee, he is asking 20% fee - He is at the moment overwhelming by demand. I'm just jumping in, because I have the experience and knowledge of doing it + I can help other people. So don't feel obliged to use our service.

As all source is open source and python is used. Everybody can look into the source that will be executed. It is not packaged. So no virus scanner is needed. At the moment the sources has 10 stars, I didn't inflate it myself. So that are already 9 independent people that have looked at the code and approved it. Ps. It should be about 100 before you should trust the stars. But we only need somebody with trust within Bitcoin to check the sources and approve it verbally here In case you don't trust our sources yet, we can always fallback to the known and approved btcrecover.

Economy / Services / USW Bitcoin Recovery Service (5% discount for bitcointalk members)

on: January 03, 2018, 07:43:45 PM

I'm Nikos Verschore from the company USW bvba with HQ in Brussel. We started our Bitcoin Recovery Service dec 2017. So just started, but are willing to help the bitcoin users. The fee is only 10% for BitcoinTalk members who give a review in this thread We are doing a trustless way of recovering the bitcoin wallet for a 15% fee. It is a technique already demonstrated here. By only extracting parts of the wallet, we never have access to the funds. We have created a GUI for the extraction, you can find the instructions and the source code on https://github.com/UwSoftWare/trustless_btc_recovery (For the experts, it uses the pywallet and btcrecover scripts and adds a GUI to it. It is freely available and may be rebranded for other recovery services). The fee only has to be payed after successful recovery. FAQ: Why should you trust me? Firstly, you don't have to trust me for doing the recovery. It uses techniques that don't put your funds in jeopardy already proved by the Bitcoin community. Secondly, I'm backed by a company. So it is possible to create legal binding contracts Thirdly, if I'm doing something fishy, that person should post here as fast as possible! I life from my reputation. So if something goes wrong, warn others here! (I'm trying to convince some of my successful recoveries, to comment here un-anonymously) We can we do the extraction trustless if you have one of the following wallet: Blockchain.info Bitcoin core Bither* Armory* Electrum* Multibit* _{* the extraction scripts will be added to https://github.com/UwSoftWare/trustless_btc_recovery when a client needs them} When can we recover your wallet? Blockchain.info: -- If you have access to the email account used to create your account + a fairly good guess about your password -- or If you have a fairly good guess about your seed (be aware this is not trustless, only engage if you trust me and my company) Other: -- If you still have your wallet + a fairly good guess about your password -- or If you have a fairly good guess about your seed (be aware this is not trustless, only engage if you trust me and my company) What is a fairly good guess about your password? Your password is maximum 7 characters, but you don't know anything else You used an english word with 4 numbers after it You used 2 words out of the bible with some exclamation mark You know your password but it is not accepted and think that 1 to 4 characters are wrong You have a list of passwords your normally use and used a combination of that What is a fairly good guess about your seed? You know 10 or more of the 12 words You are uncertain of 3 of the words (because you have written them down, but cannot read it back) How come we can crack your passwords? First because, we humans, create bad passwords. So if you didn't use a password generator and have made your passwords like you created your other passwords. Then we can abstract the knowledge about how you are creating your password and use that logic to create potential passwords for your wallet. Sadly (and luckily) the wallet use strong encryption that makes it very slow to do guessing of the passwords. 10billion/s for md5, against 50k/s for wallets. Luckily we use a farm of GPUs to fasten the recovery. What is trustless recovery? By not giving your full wallet, but only parts of the wallet, you don't give the real access to your funds. These extraction scripts are implemented by the most-know btcrecover. We used these scripts and added a GUI wrapper to make it a easy to use program. What is USW bvba? Should I trust that? We are a company in Brussels, Belgium. We have customers like EITDigital, IMEC, University Ghent. Normally we create custom software for our clients. One of the projects is create a learning platform based on blended learning. The second part of our company is busy with creating a Drone Light Show (First show this summer). As Bitcoin enthousiast and having the knowledge about running the GPU servers and also doing the recovery, we brought this service to everybody. Nice thing about the backing of a real company is that we can create legally binding contract if necessary. Are you doing the services remotely? Yes, I'm willing to come to the client to recover data. As I cannot guarantee recovery, all costs should be payed upfront by the client. But the better option (and mostly used for 100+ BTC) is to recover it trustless and then once successful recovered. The password and fee are exchanged on location.
