Title: Re: HELP ! How to restore an encrypted bitcoin wallet Post by: HELP.org on September 14, 2014, 02:56:28 PM I am sure some experts will chime in as I have never run it myself. I have always used a deterministic wallet where one key generates all the keys and you don't have this problem.
pywallet.py is a program used to get data from Bitcoin wallets that may have been damaged and can't be opened by the program. Python is the programming language and you will need to install an interpreter so that python programs can run on your computer. Here is Python for Windows: https://www.python.org/download/windows/ one you install that you can run Python programs such as pywallet.py Title: Re: HELP !

Check https://bitcointalk.org/index.php?topic=34028.0 for more details. Python is a language like C, C++, Java etc... Pywallet is written in Python language, that's why it is pywallet where py stands for python. It has many features, mainly related to restore/backup of wallet. ~~MZ~~ Title: Re: HELP ! How to restore an encrypted bitcoin wallet Post by: joyyen on September 14, 2014, 03:16:51 PM i have installed the python 2.7.8 so what is the next step ?
can anyone send me a full tutorial link ? Title: Re: HELP ! How to restore an encrypted bitcoin wallet Post by: deepceleron on September 14, 2014, 03:26:02 PM Asked both of them now. Awaiting response :) The second that you say the word "format" or "repartition", the only hope is to yank the drive from service and scan the whole surface for any recoverable private keys. Data likely will no longer be where it should be, recovery software will find junk in the sectors where "wallet.dat" is indicated to have been. After IMMEDIATELY discontinuing use of any drive with possibly-recoverable bitcoins on it, you need to boot another operating system off another drive, and use software that will mount and scan the entire original drive by raw disk sector to discover any recoverable private key data that could be left on the drive. Get a second hard drive to run off of or bootable USB with a linux distro on it, and get pywallet running on it: https://bitcointalk.org/index.php?topic=34028.0 Then use the command below, pointed to the appropriate device corresponding to the old hard drive and the correct drive size/area to scan, pywallet will go through these steps: 1. read every byte on the disk to look for keys 2. create a recovery file of private keys which enables 3. attempt recovery of password-encrypted keys using possible phrases python pywallet.py --recover --recov_device /dev/sdb --recov_size 120GB --recov_outputdir ~/foundkeys It takes about 10 hours to fully 0-wipe a 2TB hard drive, expect longer for key recovery just to read and process the whole drive. Several threads are around discussing this, but there is not one that is at "master tutorial" level. Title: Re: HELP !

Title: Re: HELP ! How to restore an encrypted bitcoin wallet (bounty 0.04btc) Post by: deepceleron on September 14, 2014, 06:53:11 PM If the wallet.dat backup was made AFTER you encrypted it, and you haven't made more than 100 transactions, you backup should still be current. The wallet file has a pool of 100 future addresses to keep the backup from becoming obsolete for a while, however, when you encrypt it, the unused address in the pool are replaced with new addresses.
Problems restoring a backup like you indicate are usually from corruption by copying the wallet.dat file while Bitcoin is still running. The safe way to make a backup is to use the menu option in the program. The only file that contains your bitcoins is wallet.dat. If you formatted or erased the partition containing your wallet, then you must find a valid and working backup. If you do not have a backup that works, the only hope is to have immediately stopped using the disk with the deleted partition, so that data recovery can be done as I outlined above.

Thank god ! Title: Re: HELP ! How to restore an encrypted bitcoin wallet (bounty 0.04btc) Post by: HELP.org on September 17, 2014, 03:16:23 AM Use a deterministic wallet and backup the key remotely. If you don't label it as a Bitcoin wallet backup key nobody will know what it is.

Thank god ! congrats Title: Re: HELP ! How to restore an encrypted bitcoin wallet (bounty 0.04btc) Post by: joyyen on September 20, 2014, 06:24:36 PM i Just realize that This option can also solve my problem
as today i have found out i have the same problem on my dogecoin wallet so i followed this instruction On others post by sonny I have never got this problem, so I have no idea why it happens and how to fix it. https://en.bitcoin.it/wiki/Running_Bitcoin Code: -salvagewallet Attempt to recover private keys from a corrupt wallet.dat If you are using Linux, run "./bitcoin-qt -salvagewallet". If you are using Windows, make a shortcut for your bitcoin.exe and append "-salvagewallet" to the target, and then open the program using that shortcut. If you have any bitcoin in your wallet, do NOT delete your wallet.dat, or you will lose your bitcoin. If you have no bitcoin yet, feel free to delete the wallet.dat file. Thanks god now i also recovered my Dogecoin wallet ! |
