Wallet.dat

The wallet.dat file contains your private keys, public keys, scripts (which correspond to addresses), key metadata (e.g. labels), and the transactions related to your wallet. If you have an HD wallet, it also includes the HD seed and the derivation paths for each private key.

I had about $8 USD worth of bitcoin in a wallet, and I backed up the wallet.dat to my dropbox. According to the modified date of the file this was in April 2013, so it was probaby from bitcoin qt version 0.8.1, or maybe a little earlier.

I downloaded the latest version of bitcoin core, added the wallet.dat file to the data directory, started it with -rescan, and waited almost a month (!) for the blockchain data to get up to date. The balance showed as 0 the whole time. I thought it would update once the blockchain was totally downloaded, but it still just says 0.

In the JSON dump of the wallet.dat file, you will find the private key, in the field labeled "sec." Don't share that with with anyone. That key will allow anyone to sweep your bitcoins into their wallet.

Bitcoin wallet.dat allows you to store your public keys, private keys, scripts corresponding to your addresses, and key wallet metadata DAT file on your computer. Tracking your wallet transactions, such as labels, is also possible.

Note: When you back up these DAT files, you can name them LitecoinWallet.dat, Bitcoin-backup.dat, and so on. However, when restoring the wallet.dat files, ensure you rename them back to wallet.dat. Its recommended not to delete wallet.dat files. Just rename them to old-wallet.dat files.

A Bitcoin wallet is stored as a wallet.dat file that is partially encrypted using a user generated password. The private key of your wallet (a 256-bit number) is symmetrically encrypted with a random master key and that master key is subsequently encrypted with the user-defined password. The wallet.dat hash then, is the converted binary blob of your wallet into a human-readable string of letters and numbers. This answer assumes that the extraction was done using a JohnTheRipper script and may not necessarily be accurate if another method or hash was extracted from the wallet file. The assumed script referenced, to be exact, is the bitcoin2john.py. If an alternative method was used, this answer might not be accurate.

Because there are a number of ways to extract some form of hash from the wallet.dat, there isn't specifications about how you came about getting that hash, and because various wallet software operates differently from one another, I can only speculate what process and wallet you used in saying that: for the most part your assumptions are correct. I would just make a note to clarify that the first string is the "hashed form" of the master key as broadly explained in the answer to the first question. Remember that the master key is encrypted using an encryption key which was generated from the user password.

This should be partially covered by the answer to the first question but to summarize as an example, (and not getting into too much of the technical details that you yourself can, with due diligence, find online) and with a need to oversimplify a complicated process; if you had 100 words that you think might be the password, Hashcat would hash those prospective passwords based on the information provided from the wallet.dat hash, which includes the salt, iterations, etc. among other things. Most hashing constructions are more complex than simply concatenating a password and salt but in this case, Hashcat is using the applicable and identified algorithms it has been provided to apply those to the list of prospective passwords (AKA wordlists) it's been given and generates a hash as if it were the password and then compares the resulting hash to the wallet hash to see if there is match. The work is, at the lowest level, a hashing and guessing game to find a match. Once it finds a match, depending on, again, the settings, it will either stop, go through the rest of the words in the word list, or closes. In the case of the last option, you would need to run Hashcat again with the option of revealing the hashed passwords.

Hardware failure, software failure, data corruption, blue screen of death, device stolen or whatever it is. As long as you have your wallet backup file stored safely; you can access your coins back. Wallet backup is the most essential measure you must consider in order to keep your holdings safe. There are two ways to backup your Bitcoin core wallet. 1. Wallet.dat and 2. Private keys. For the first one you need to simply copy the wallet.dat and put it in a secure location. For the second one you need to use your wallet console window to export private keys.

If you are exporting private keys then remember that each wallet address has a unique private key associated. So make sure to export the keys for each and every address for which you have funds. Store this private key information in a USB drive or write it down in a safe place where no one can access this. But for how many address? We know getting private key for each address and managing them is quite difficult. Also if a single letter or digit of your private key gets misplaced then there is no hope of recovery. For this reason we also recommend you to backup your wallet.dat file. For better security both options are recommended and this particular article explains both wallet.dat backup and exporting private keys in detail.

Note: This core wallet backup and restore tutorial is not only for Bitcoin core but also applies to all other cryptocurrency core wallets. Also this guide is for Windows, but the procedure is same for Linux as well as Mac. The wallet.dat file is cross platform compatible so you can move across different computer or an operating system.

Note: When you backup you can name the file to anything. For example Bitcoin-backup.dat, LitecoinWallet.dat, Dashbk.dat. But when restoring this file make sure to rename it back to wallet.dat. Also very important that before you restore wallet.dat with a backed up file check whether if the current wallet is storing any coins. If it is so then backup that as well or send the coins to the wallet address that you control. We do not suggest deleting wallet.dat. Instead rename it to old-wallet.dat or something.

Go to File -> Backup Wallet. This will generate a wallet.dat file, which stores a list of all the key pairs you have used. Restoring this file will give you access to your Dogecoin. Store it somewhere safe, in a device not connected to the internet.

IMPORTANT: wallets created with Dogecoin Core releases older than version 1.10, instead, contain a list of randomly generated private keys. Even when imported in Dogecoin Core 1.14+, these wallets will keep using this way of generating addresses, so whenever you generate a new public address with Dogecoin Core or you spend coins, it is recommended that you create a new backup, as the old wallet.dat files might not contain a copy of the private key associated with the new public address or with possible change addresses - thus, upon restoring the wallet, you might be missing part of your Dogecoin.

The wallet.dat file is not a plain-text file. It is a BDB (Berkeley Database). For this reason, it might be a good idea to create a plain text backup of your wallet, containing a list of all private and public keys currently in use by Dogecoin Core. In order to do so:

I was thrilled. I went to the internet to check. The address indeed contained some fractions of a bitcoin. I searched my file system for a wallet.dat file and got lucky. There it was, under /Library/Application Support/Bitcoin/.

First, I made sure all my Wifi and Bluetooth connections on the laptop were turned off, and the laptop was not connected to the internet. Better safe than sorry. Second, I created a safety copy of the entire directory and put it on a memory stick. Third, I removed all access rights from the wallet.dat file using sudo chmod a-rwx wallet.dat to ensure nobody, except myself, could by mistake or with bad intent read out or modify the wallet.

I own a new MacBook Pro, so in theory I could have installed a new version of Bitcoin Core there and then try to import the old wallet.dat. But the problem was that Bitcoin Core these days require at least 320 GB of disk space, and I only have 512 GB available, with roughly half of it already filled. So, there simply was not enough disk space available.

Next problem was that I had no clue how to import my 2011 Bitcoin wallet.dat into Electrum. I searched around and found this medium.com post from 2017 that in the end turned out to be quite helpful yet leaving out some details. From what I understood from this site and other related material there was simply no way how to import my old wallet.dat file into Electrum, they were incompatible.

Depending on the size of your wordlist and complexity of the password, this can take a very long time. Also Please only use this method on your own wallet.dat files! I hope you are able to now recover your wallet.dat password.

This documentation describes how to safely back up your wallet file forsafe storage in case your computer or laptop is damaged or lost. DashCore stores all data necessary to control your Dash addresses in asingle file called wallet.dat. This wallet is in the Berkeley DBformat and stores the pairs of private/public cryptographic keys used tomanage your balances on the Dash blockchain. Dash Core makes most ofthese operations transparent and even generates automatic backups ofyour wallet file in case it is corrupted, but the user is responsiblefor ensuring that these backups are stored in a safe place. If youlose access to your wallet file, you will permanently lose access toyour Dash. 041b061a72
