Did Ethereum ever use wallet.dat?

I could've sworn this old wallet.dat file of mine was from some random mining I did very early on but figuring out how to access it has been a PITA.
Once a year or so I've been coming across the file in my backups but after a little searching for accessing it I give up. I downloaded Bitcoin and Litecoin core tried it there and no luck and I don't think I mined anything other than those and ETH.
Any help here would be appreciated! Thanks.

Need help with old wallet file

Hello,

I used to mine Bitcoin back in the day, but then stopped for the reason I don't remember. Somehow I lost my wallet file, I think I just got new computer and did't transfer the wallet file.
Few days ago I was going through old flash drives and guess what, I found old wallet.dat file, it was waiting for me on the drive :))
Now I'm supper happy and exited, but I can not remember my passphrase. I know for sure It was one of the nicknames I used + 5 random special characters, total 12 chars.
I know which nickname I've used 100%, but have no idea about the special characters. So.. my password is XXXXX^%#@! or something like that.
I've tried number of passwords, I'm writing down passwords on paper and trying different combinations, but this is frustrating :(
I need some help with this. Whoever helps me to recover my BTC will get nice reward.

I'm sure about first part, don't remember special characters..

Running with Elliot????? , looks like it would take few hours on my video card.

Got suggestions in PM to add space in the beginning or end also trying all lowercase.
so will be trying these :
EDIT4: All those combinations didn't crack my wallet, not sure what to do now. ( I sent it to Dave though)
Couple people in PM suggested to post wallet hash here, so I managed to extract it, here it is:
$bitcoin$96$cb210f922805aa13ba72fb38d921884917ab3056a5f008887c38c79ba391b2edc820df06567a962c65f909c7d9e16dc5$16$7ac499ba7b78e1d8$225043$96$8675736541d6cf4fab984563730c345a631ae3aab9efe108bce6d3c3ef0461b19f024a86aed6aaaaaffc7f52a16a0565$66$03fffad60604333b736c5aa526d4e4af42fb7c9cfd25046fe6036b79c44ed23c12
EDIT5: I have no luck recovering the password, everybody I've contacted are unable to help me so far.. so
I've decided to sell my wallet as been recommended multiple times in PM.
I can not recover the passphrase so can't use any BTC inside the wallet , selling it to whoever can crack the wallet hash would return me some of my BTC.
You can buy my wallet here - https://satoshidisk.com/pay/C7Vb2p

'''
This is an increased reward since my previous post, and also I have got a potential hint now
Hello,
I have old Bitcoin Core wallet files that I remember possible parts of the password, I think it was encrypted in 2013, and that it was likely (but not 100%) without special character but including numbers. So the password might be crackable, also it was most likely in Chinese (probably simplified but maybe pinyin).
The way you have to do crack this is by using the [extract scripts here]1 which will be enough to get the wallet.dat password, BUT not enough to steal the BTC in the wallets. It just contains the encrypted master key and some other info.
I have a total of more than 10 wallets all with the password generated on the program, totaling to about 100 BTC. So you'll get 20% of each wallet you crack. See it as the hunger games as I'll let anyone with good rigs or chinese dictionary work on it!
But I'd like to start with one first. If you can do this, message me about your chinese password dictionary or what you can do. Don't bother messaging if you have a poor computeGPU, it will take years! Or if you have a new/throwaway account...

Simple methods for physically protecting your Bitcoins from armed robbery and theft

One thing about Bitcoin is that it goes back to Gold. In times where Gold (and similar currencies) were popular Robin Hood, Jesse James, and other street bandits could make fortunes robbing stage coaches in transit. If Bitcoin becomes more mainstream, times like these could come again.
While it seems far fetched, robbing a house built on fiat has the reward potential of about $25,000 tops. It's not feasible to execute a bank transfer, make a HUGE purchase on a credit card, or ATM withdrawal more than $1,000 or what not. Anything in under 1 to 2 hours is limited to $25,000.
Except with Bitcoin. Hacking an exchange, or robbing a person, has virtually unlimited potential, and millions can be transferred in minutes. It's the most profitable form of person to person armed robbery bar none, with second place capping out at around $25,000.
So what do you do?
Remove any possibility of a thief acquiring more than $25,000. Will this create some hassle? Sure, but for social leaders and millionaires, it's likely worth it. For anonymous individuals of low profile, IT IS STILL IMPORTANT, because one needs to have a good story.
During a robbery, you want to do the following:
There are two things necessary to achieve this:
1) Attempt to PREVENT withdrawals from exchanges to unknown Bitcoin addresses, or other wallets altogether. And to put new addresses on a one-week lock. 2 Factor Authentication does nothing for you in the event of a robbery. Instead, only allow withdrawals to 1 BTC address, the one in your bank vault.
2) Make a multi-signature wallet on Bitcoin Core or other, 2 of 4 (or 2 of 6 or similar). Unlike other methods where the passwords are kept with friends or family, instead get FOUR safe deposit boxes in four separate banks. Within each bank keep ONE password and a USB drive for your wallet .dat file. In order to access your 'vault' you MUST visit TWO different banks, and access your safe deposit box in each.
For Accounting purposes, you should do the following:
All Incoming Funds -> Vault BTC Address (multisig 2 of 4)
Decoy Stash (small random incoming funds, etc, transfers to Trezor, large and midsized outflows). USB drives or similar. Transfers mostly to keep up activity.
Trezor (or mobile hardware wallet) - For small outgoing purchases, minor trades, etc - mobile, safe to use on public machines.
tl / dr : So in the end, you should have:
  • Hot Wallet (Trezor) for shopping, trades ($5,000)
  • Decoy Stash ($10,000)
  • Real Stash, Vault - 2 of 4 multisig - in 4 Bank Lock Boxes, password in the boxes, 1 per Bank (Millions). With all incoming funds set to pay to this public address (or these public addresses if you have multiple businesses, etc).
  • Exchanges - Require pre approved BTC withdrawal addresses, new addresses 1 week delay prior to transfer, etc.
Such a setup such as that caps the ability for any armed robber to score more than $15,000 off your person, does not require (significant) coordination with family members (nor jeopardizes them), and forces your person to be transferred between two banking institutions before accessing significant funds (allowing for time to phone the police, and for them to arrive at your future destination, etc).
Even if you do not take these precautions, it is important to have this 'story' ready, so that you can discourage a robber from accessing your 'vault'. Simply tell them it is held in a Safe Deposit Box at 4 banks, and that you need to visit 2 of the 4 banks in order to access the funds. Such a setup takes 90 minutes for you to access funds as needed, but makes any form of extortion next to impossible. It's a highly believable story, and keeps you safe.
However, keep in mind making a token offering (say $1,000 to $10,000) can make a robber very happy, and keep them from going home empty handed. Just something to keep in mind. So there you have my suggestion as to how to physically protect your Bitcoins, and understanding the realities of physical threats.

Could I reasonably attempt to brute force the password to an old TrueCrypt volume of mine?

I had $20-30 worth of bitcoin back in 2013 when mining first exploded, where the price was about $1000 per Bitcoin. So, given the recent explosion in Bitcoin price it got me thinking about trying to find my old Bitcoin wallet and see if it has anything left in it. I found my old hard drive and plugged it into my computer to copy the files over. While I had labeled the drive "ALMOST DEAD" and it regularly made clicking sounds while plugged in, I managed to copy over my Documents folder from it. On there I found my Bitcoin folder, with a 16GB copy of the blockchain (oh, how times have changed...) and a "wallet.dat" file. Awesome! Trying to import it into BitPay brought me to a new issue; I don't remember the password! I tried all of the possibilities that came to my head, and none of them seemed to work.
I poked around a little folder in my old files and found an encrypted TrueCrypt volume. At the time I did like to save my important passwords that I couldn't change in text files, and store those in a TC volume. So there's a reasonable chance that volume contains my wallet decryption password.
So here's my question; would it be futile to set my computer loose on that volume and try to brute force the password? My knowledge of security at the time wasn't great so I think it's reasonably likely that the volume was encrypted with an 8 character password, maybe a 10 character password, that was just alphanumeric. I know that for cracking an MD5 hash that would be a hilariously easy crack, but for a proper hashing strategy, like bcrypt with a cost of 12, that becomes a serious issue very quickly, because calculating one hash takes a long time. I don't know whether there is a "hash" function to calculate for trying a password on a TC volume. The volume is 100MB; how long would it take to try one password on that? My computer has a GTX 1070 and i7-6700k with 16GB of RAM; does that help me here? If I can, what tool would I use to automatically try all of the combinations, or is there a simple script I should write?
Also, would it be better to try to crack the password to the Bitcoin wallet directly? I'm assuming not.
TL;DR: Cracking a 100MB TrueCrypt volume, with a GTX 1070, i7-6700k, and 16GB of RAM, most likely a 8-10 character alphanumeric password. Can I do this? If so, what tool/scripts should I use to implement it?
Thanks!

Help with wallet.dat file

I work at a pawnshop and just spent the last two months or so going through a little over 250 laptops we have here, An old HP DV9000 we took on pawn in 2012 and an apple MacBook Pro 13 that was pawned in July 2014 that now has a cracked monitor but both have wallet.dat files . What do I do to check for bitcoin or check the computer further?

Dave Bitcoin of walletrecoveryservices.com just cracked a wallet for me (whose passphrase I lost in May).

Background:
In May I got the "brilliant" idea of beefing up the security of my BitcoinQT wallet by replacing its password with a longer passphrase. Somehow I managed to mistype the passphase twice. I tried every thing I could think of (adding spaces, inverting capitalization, etc. etc.) but without success, even automating the guesses with a simple script from someone on bitcointalk.
Eventually I wrote the coins off and my next wallet passphrase was typed with extreme caution. (Plus I switched to using Armory where the paper backup feature is a nice safety valve.) I gave the wallet.dat file to a few people who contacted me via the bitcointalk forums, and thought that was the end of it.
So last night, I'm obsessively watching the BTC-CNY exchange rate like everyone else, when I get an email from one "Dave Bitcoin" who announced that he had cracked the passphrase (after more than 5 months!). In short order he sent me 2.0 of the original 2.5 BTC in the wallet (keeping a finder's fee we had agreed to when I originally sent him the wallet file, not that I was in a particularly good bargaining position).
It was a very pleasant surprise that he (a) was able to crack the wallet, and (b) was honest enough to return the coins. He mentioned in the email that part of his motivation for (b) is that he has started a business doing wallet recovery. I figure the least I can do is vouch for his competence and integrity. So all you morons out there who lost a wallet like me, consider using Dave's services at http://walletrecoveryservices.com/.

How to store your cryptos at home

Hello everybody,
I was an early adopter of cryptos. I started with Bitcoins in 2013 and operated with Localbitcoins and MtGOX. After the MtGOX crack (where I lost close to 10 BTC) I decided I was going to manage my cryptos at home.
Thus, I installed Bitcoin Core, synchronized and moved all my remaining BTCs home. I've been 4 years executing it on a weekly basis. Over 100Gb of DB and longer and longer waiting times made the process more and more painful for my Intel I3 old pc.
Then ETH and LTC and other coins appeared. I got into them via Kraken and decided to do exactly the same: ethereum node and Litecoin Core executed localy and backups of my wallets.dat files.
But that is just not possible anymore. ETH is extremely slow, my SSD is full and I just cannot have the PC working 24h to synchronize fully.
Now I have everything in Kraken and I fear another MtGOX.
So my question is: how can I safely store my cryptos at home without depending on an external agent?
Thanks a lot!
TL;DR: I store my BTC, LTC and ETH runing the core apps in my home PC. I don't have enough Hardware to continue doing that. What are the alternative solutions that don't rely on third parties?

'''
That's not true. The core has more features than electrum- it just requires use of the CLI. Honestly, you shouldn't be using multi-sig in the first place if you can't figure out how to generate an address using the CLI.
Open up the debug window CLI tab, type `help' and you'll see how much you can do and the information you can ascertain with the core node that you can't with electrum.
Electrum relies on the core node for all of its functionality, save their proprietary mnemonic seed backup algorithm, which is much less secure than BIP33 (which can be generated with the core; electrum literally provides you with the dictionary to carry out an attack on its addresses, and it doesn't use an EC in its cryptographic process, meaning the encryption entropy is low and the nonces are predictable).
I could order some RIPEMD-160 ASIC chips for $2/piece and have a Chinese fabricator design a PCB using some cheap 22nm SHA-256 chips and the RIPEMD chips, replace cgminer or bfgminer's computational sections with the ultra optimized vanitygen algos for brute forcing priv keys, switch out stratum for JTR-style threaded rainbow tables based on a few hundred thousand rounds of mnemonic generation using electrum's suite- along with some open source code analysis, and in a month I could create a machine that could generate and test hundreds of thousands to millions of mnemonics per second.
The only reason this hasn't been an active practice is because destroying bitcoins keypair-cryptography (or at least appearing to have done so) would send the price under a dollar in 24hours. An update would be patched within a few days and it should be a lot of hard work for nothing. But I wouldn't be surprised if this is occurring actively on a small scale, with old addresses presumed to be "lost." Even if an active address was hit, as long as it wasn't overdone, people would shrug it off as a physical compromise of their own network/machine/software, not an epidemic- but considering the frequency of exchanges getting "hacked" and the actual ease by which the attack could be carried out, I think there's an equal possibility that the security is already completely compromised.
Theoretically all mnemonic backups are inherently insecure (as is any password using dictionary words, no matter how long) but at least using ECDHE and a deterministic seed, you're actually getting a password with a strength equal to that of the sum of its characters as ASCI to BASE/56 encoded bits. Without that, you may as well have a 12 character passphrase (with the possible characters equal to the number of words in the abridged electrum dictionary.) So it's {POSSIBLE WORDS}12 for electrum vs. something closer to {(POSSIBLE WORDS60)(POSSIBLE HD-SEEDS)}256 for a BIP33 mnemonic using SecP256k ECDHE algo (assuming average number of letters in a word are 5 and HD seeds are pseudo-random.) But mnemonic seeds are still insecure even with BIP33. Use the core wallet and you get a key with true randomness using entropy from blockchain derived sources, 2 rounds of SHA-256 and a final RIPEMD-160 round with a 256-Bit secret generated in conjunction with with an extremely secure ECDHE curve=trillions upon trillions of possibilities. That not only makes a single key harder to break, it means there is a much less likely chance of someone randomly guessing secrets and testing them to see if they come out to a funded address in the whole scheme of things.
It's like if I tried to break into every Dell server. If many people were using weak passwords, and I could try a password on all of them at the same time- I'd surely crack a bunch, and make Dell look bad as a company, even though the servers were inherently fine. Keeping the network strong means making sure you do your part to save face, after all bitcoin is owned and CONTROLLED by the userbase.
As a side note, RIPEMD was only used in the public scheme along with SHA256 (despite being significantly weaker) because at the time SHA256 was the only widely implemented and highly secure algorithm- meaning it could be as widely adopted and widely mined as possible. So SHA-256 was the logical choice for the main block algorithm. There wasn't another option for the wallet address' scheme that would be secure tunneling enough and still computationally feasible and easy to integrate. So SHA-256 was most secure, but without the round of RIPEMD-160 as the deterministic round, wallets could be brute forced at the same time as mining, with the same hardware.
For the most secure, fool-proof, uncrackable wallet, here's what I do/used to do: Use the Core node to bake Segwit P2SH addresses. I don't use HD wallets period, but HD is secure enough as long as you're using a truly random secret. Remember that the secret in a BIP33 HD wallet is the master privkey, additionally, each address has it's own xpriv, which, considering the combinations possible, saving the individual xprivs makes the most sense anyway. If you plan on spending the coins soon, just secure the wallet .dat file with a strong 16+ character (A-Z,a-z,()$&@#$/?¿%÷,0-9) passphrase (this is just the wallet file pw it has nothing to do with your addresses) then just throw the wallet on a flash drive or better yet an SD card or 2 and call it a day.
For addresses you plan to put on ice for a while, concat your coins into a handful of accounts, don't store more than $1,000/address. Then using the `dumpprivkey' Core CLI command (I think that's the command, it's something like that, type help and you'll see it if I'm wrong), a text encrypting program (for good measure) and a barcode/QR code generator (all offline!), get the private keys for each address, encrypt the text with an easy to remember password (you'll be taking the keys offline, and storing physically, so no need to worry too much about that pass, it's better to just keep them physically safe), and then generate QR codes for each. Paste them all into a word doc with the corresponding (lightly) encrypted numbers you generated the QRs with. Print out a couple copies and then delete the addresses from the wallet.
Put those paper wallets somewhere safe. You could also split the key down the middle and store the 2 parts of the paper wallets in different places instead of encrypting the plaintext xprivs. So you'd need to scan both paper keys and paste the solutions together to access the coins.
That's all a bit extreme... in reality, unless you're super paranoid and storing millions, you'll be fine by keeping your coins in the core node with decent firewall and a good .dat passphrase.
BUT ELECTRUM IS NO GOOD!

I recovered my lost Bitcoins!

Just thought I would give an update to this post. It’s related to the issue of change going to a different address that has been in contention lately, so figured it was relevant.
I managed to get my coins back today, and wow it feels good!
The cause of the missing coins was because I was making payments from the same wallet on two computers while they were syncing with the block chain. For whatever reason, a change address for a transaction went missing. I had tried many times to load different wallets and rescan the blockchain again and again and never had any luck. In the end I had a mess of different wallet files, 16 in total, none of which included the relevant address when loaded in Bitcoin-qt.
Well after the price went over $100 I figured I would have another crack at it and took a different approach to see if I could recover the coins.
I installed pywallet and did a dump of each wallet file that I had. I have never deleted a wallet file and this is what saved me.
I searched the dumped wallet files and in one of the files I found the address I was looking for! I assumed I must have missed this wallet so I loaded up Bitcoin with the relevant wallet and let it sync….
I was disappointed; the transactions as they loaded did not contain the change I had expected. But I had seen it in the dump of the wallet.dat it must be there!
I ran the following command within the Bitcoin console after unlocking the wallet.
Dumpprivkey  
My heart skipped a beat, it returned a key!
I then imported this key to a blockchain.info wallet using the import feature and my balance adjusted! I had recovered my missing Bitcoins! I then transferred them to my new secure wallet and the transaction confirmed, happiest day of my life.
Here are some things I have learned that should probably be common knowledge for anyone using Bitcoin.

Here's my situation.....
I know this is an all too common problem (and you've probably heard a lot of similar stories) but I'd appreciate any advice I can get. I purchased some bitcoins back in 2013. They were in a Bitcoin-QT wallet on my now very old and slow Macbook (which I still have). However, I wrote my passphrase on a piece of paper that is long gone now! I'm well aware that without the passphrase or seed phrase I'm unable to recover the coins.
HOWEVER, I might know part of the passphrase - but not too sure. I've now created a new BitcoinCore wallet and have imported the located the wallet.aes.json or wallet.dat file from the old mac (just waiting for the initial synchronization which should be finished in a couple of days.
I know it is difficult (if not impossible) to crack the passphrase via brute-force but I just heard about new Forensic software called Passphrase ([[link]2 ) that apparently has the ability to recover lost bitcoin passwords from Bitcoin.info and Bitcoin Core wallet services. It is very expensive (USD$1,095/year) but just wondering if anyone has used it before or knows how effective it will be in my situation.
Hoping someone can help!!!!!
Thanks

I'm giving away Bitcoin

Hi guys. I realize this is pretty dumb, but I've lost the passphrase to my old Bitcoin Core wallet. I've tried quite a few bruteforcing apps with no luck (duh), old backups(no use), wallet recovery services(not interested) et cetera.
Thanks for staying this long with me. Almost there. So, why I'm here is - I'm going to share my old wallet.dat's and ask y'all to crack them. As a reward you can keep 50% of money in the wallet, which is 5$ and not a cent more. That should make around 70$.
Now, I perfectly understand that if you do manage to get the money, nothing would be stopping you from taking all of them. Well, on the other side I believe that it still would be better than the money laying w/o use. Besides, Redditors are awesome.
The passphrase is about 13 digits long, with no repeating symbols. The minus is that it can contain any keyboard symbols (Uppercase, lowercase letters, numbers, and [email protected]#...) The files (wallet.dat backups) are up on google drive - https://drive.google.com/drive/folders/0B3eCKZXI79O8aklyUUk5WXBtWGc?usp=sharing I wish you good luck.
P.S: Sorry for the, uhm, title.
P.P.S: English isn't my native language, so have some mercy.
P.P.P.S: I can provide any ownership proofs. Say, dance around my PC with transaction history onscreen?
P.P.P.PS: Yes, I'm fully aware of the fact that I'm not very smart.

Old Wallet.dat into new Bitcoin Core Wallet - Locked and zero balance/history

I put some BTC on an old bitcoin core wallet which was on an external USB drive back in 2015. I then encrypted and locked it with a password. I now want to retrieve the coins but when I attached the drive to my current laptop, I am seeing zero balance and no transaction history. I spent about a week downloading the entire blockchain again, now up to date but it is still showing zero.
However, the password I noted is not working and the wallet is locked. Should the bitcoin core wallet show the balance when the wallet is locked, or do I need to put in the password first? I thought the password was only required to send. I really want to see the balance, so that if there is something there (I really thought there was, and if it's empty why would I have locked it in the first place).
I can't export the private key without the passphrase. I also tried the dumpwallet keys.txt command in the console but unfortunately I get met with:
Error: Please enter the wallet passphrase with walletpassphrase first. (code -13)
I'm assuming that as the wallet.dat has been moved to a new client, it wont show me anything at all until I unlock the wallet.
Before I start launching into btcrecovery to try and crack my own password, is there any way I can see my balance or any public keys from the wallet.dat ? I would rather not go through it all and then find the balance really is zero.
thanks for any help
