-snip- you don't actually need to worry much as there are some scripts which you can perform on your PC which can take out the password from .dat file. -snip-
Its not as easy as you might think. Lets say you have a good randomly generated password with 6 alphanumerical symbols [a-z,A-Z,0-9] and remember nothing about it. Thats 8 62 possible combinations. With 1600 passwords checked per second (its roughly what my GPU does on bitcoin core wallet files) it would take 1.9*10 45 years to crack the password. Testing a few million passwords is no problem though, but you will have to remember a lot about your password to get there. You can´t check 1600 passwords a second, sorry to dissapoint you. Most properly written encryption software will allow 1 per second if the iterations are set high. In your case, you may need the help of a professional. If you had a passphrase with a high bit rate you are going to have to remember a good portion of your password, and then a script can be written to attack it. Again though, if the encryption for the wallet was written propertly, you may only be able to try 1 password per second. I used a script written by someone else to crack my LUKS encryption password to a flashdrive. I knew what the pw was. just didn´t know what symbols I added to the beginning and end. I was able to incorporate the symbols I thought were used in the script and after several days i got it. however, i knew most of the passphrase. LUKS encryption only allows you to try 1 password per second because of high iterations. The other option may be to try to do a forensic search to see if the password was cached somewhere? This is unlikely however, as good encryption software prevents this from happening.

Its not an estimate. Btcrecover[1] achives ~1.68kP/s on my GPU (GTX 970) vs. bitcoin core wallet files. I cant get it to work with UTF encoding, which slows it down significantly for certain passwords, but that might just be a problem on my end. The CPU (4th gen i5) does ~360kP/s vs. multibit key files (no GPU support) using the same set of tools. Things like the saber cluster[2] will rip weak passwords a new one and thats a "cheap" 1 year old cluster. Most properly written encryption software will allow 1 per second if the iterations are set high. In your case, you may need the help of a professional. If you had a passphrase with a high bit rate you are going to have to remember a good portion of your password, and then a script can be written to attack it.

Yes its possible to crank up the number of rounds to slow things down or even use a nested scheme of several encryption mechanisms like e.g. VeraCrypt or TrueCrypt, however most bitcoin wallets dont seem to use it to an extent that it slows attacks down to 1 try per second. IIRC bitcoin core sets the number of rounds when creating the wallet for the first time. Its aiming at 1 attempt per second per core when it does it by itself. Its however possible to attack the wallet.dat directly or rather a certain string from it and not use core for it which can speed things up even on a CPU. Just give btcrecover a try.

What is the 1. btcrecover-tokens-auto.txt 2. tokens.txt
Cannot find btcrecover.py I look every folder inside btcrecover-master. No btcrecover.py I understand inside btcrecover-master are Python script file called btcrecover.py,but cannot find it? So where I put wallet.dat and I think tokens.txt Very confused.
You need to create the token file for your case. Its explained here[1]. The wallet file and the token can be anywhere, but its easiest if they are just in the same folder with the btcrecover.py file. If you download the .zip file from git and extract it the file is in the main folder. The same folder contains a TUTORIAL.md and a README.md.

Also I have problem with pyopencl download. In that Guide given web page download , takes to Pytonxy download page and there have not the PyOpenCL download exe. So how and where to download? I have TeamViewer and my E-Mail is: x58x58@gmail.com . I am always at computer. IF somebody looks over TeamViewer what I do wrong? Please help!

I did exacly like this tutorial say's ] https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#the-token-fileDo anybody knows where do download PyOpenCL Do we need Pythonxy ? I also did downloads for Linux Ubuntu, Downloads go smootly, but in end, do anybody knows how do use Pyhton Terminal. So, right now have problems on Windows and Linux. I think if find and download windows PyOpenCL, it will start and work and if find how give orders to Pyhton Terminal , it will work too. So, Anybody? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) ?

About five years ago I had in Bitcoin Wallet 12 BTC and I bought it $ 5 for each. I was keeping Encrypted password in Extrenal HD. Then Extrenal HD crash and I lost password. I was using that time Dell Inspiration 1750 and weeks later crash Screen. I was calculating and not buy new Screen, but instead buy new computer. Dell was work if I hooked up extrenl screen. I bought new computer and Dell computer I put storage. So, I have encrypted 16 numbers and letters lost password, but what I know is 10 password letters and numbers. 5 missing. Now I am at forum and try to put work brutal btcrecover, but at this point non working yet. So I make offer. If somebody help set up in my computer brutal btcrecover from A to B in WINDOWS, I WILL pay half bitcoin. If helping setup LINUX, I pay half bitcoin. If set up both I will pay 1 bitcoin
Option 2 I sell Wallet.dat where is 12 BTC and all password information for 1 BTC or best offer.

Ok, if I put the 1 BTC on escrow, and after making sure that your wallet indeed have the 12 BTC that you say; then escrow will release the 1 BTC to you, deal? The other option: send me your wallet, with whatever you think your password could be, and after I find the correct password and open the wallet, I'll keep 20% of it and send you the rest.

I am tired at this bull sh talk. You just living paycheck to paycheck and have not money for 1 BTC. There always be some one who are serious and want do good deal. So knock off your Bla bla bla talk and I will be a round and wait who have that little money to invest and take good profit from it.

Yep that must be it. Its impossible that its that you are #1 a newbie account that can easily fanish without any consequences #2 unable or unwilling to go an inch out of your way to make a deal happen #3 unable or unwilling to accept commonly accepted help #4 unable or unwilling to even show an address or otherwise prove that you own the claimed amount in the past. Just go back to grinding faucets[1], no one here is stupid enough to fall for your attempts. [1] https://www.blocktrail.com/BTC/address/1KNxTij6FFN2Y7HrpPXTGxz79zWsP6ZKgk
