Hi i lost my seed from multibit but i do have my password. Wanted to recover my seed with "decrypt bitcoinj seed". When it asks my password and i type it down it says incorrect password. This is very strange because i can log into my wallet with that same password. The wallet file is also encrypted. Could you please help me with this.... Really appreciate your help.

Bitcoin Daytrader (4 months ago)
If you have a private key you should not need to have a password and should be able to import the key in any wallet, unless it is an encrypted private key in which case I do not know how to decrypt it.

Hello, can you get me into my toast wallet? I can see my XRP , I just cant send it bc i for got my passphrase?
Bitcoin Daytrader (8 months ago)
Hi Dustin, There is a big chance that it would work in btcrecover, but you need to have the wallet file or a backup of that wallet and try to run it in btcrecover. I'm not 100% sure it will work.
Milen Rizov (9 months ago)
What about if we know only 80% of password?
Ahmed Shawky (3 months ago)
Bitcoin Daytrader what do u mean buy wildcard
Bitcoin Daytrader (9 months ago)
Hi Milen, then btcrecover is the tool for you, because you can setup btcrecover to recover the remaining 20%. You can do this by using wildcards or trying out different typos.

Bitcoin Daytrader I need help
Bitcoin Daytrader (9 months ago)
I'm very sorry to hear that. It seems that your password is longer than the amount of %9in, or that it contains signs as [email protected]#$%^& since the %in is only using digits, lower or uppercase letters. If you are sure that you have used 9 or less signs you can always try the following token.txt %P %P %P %P %P %P %P %P %P Where the wildcard %P stands for Pretty much anything on the keyboard, this token is even more hard for your pc, but since you are using a .key file you are in luck since .key files are pretty fast. Every %P creates 1 sign, letter (small and big) special letter or a number. So the amount of %P creates the length of the password, in this case 9x %P equals a password of 9 characters long.

Hey I have a corrupted backup wallet.dat will this work for that?
Bitcoin Daytrader (9 months ago)
Go to https://github.com/jackjack-jj/pywallet Follow the installation guid at the bottom of the page first. After the installations you download pywallet.py and safe it somewhere on your pc lets safe it in the C:\btcrecover-master> folder and copy your wallet there too. Go to the btcrecover-master folder in CMD: cd C:\btcrecover-master So your command window should now look like this: C:\btcrecover-master> Then you run CMD just as we do with btcrecover but you change btcrecover,py in pywallet.py To get the --help argument list of pywallet.py type. C:\Python27\python pywallet.py --help From the info of that list you can build the right command C:\Python27\python pywallet.py --recover --recov_device YOURWALLET.dat --recov_size 20Mo --recov_outputdir wallet_recovered.dat --passphrase=YOURWALLETPASSWORD This results in a new file: wallet_recovered.dat that hopefully show you your private keys. I hope you can get it to work
Skele Profile (9 months ago)
So how do I do this? But with pywallet.py?
Bitcoin Daytrader (9 months ago)
Hi Alex, I'm sorry but Probably not, It depends. If your wallet got corrupted after a wallet crash, so let say you open your wallet and your pc all a sudden turns off there is a chance by using the pywallet.py script, but this is not guaranteed. If you found an old hard disk where you accidentally deleted the wallet and used a file recovery program to get you corrupted wallet back, you probably wont get the access back, since that usually means that big parts of the wallet file are missing.

Hello, how to do if we have serious doubts about the words that make up our password (actually I have no idea) it's been years and I created a lot of passphrase .. What to do? I have a Dash Core and Litecoin Core wallet, help me please

Emmanuel Roche (9 months ago)
Ok no problem, thanks for your answers! It was in 2014, the codes I used have not changed much since then but I tried everything and nothing makes it .. I have to try all combinations, there is a lot of dash and ltc on these portfolios .. If you do a tutorial on it one day, I'll be the first one! thanks dude
Bitcoin Daytrader (9 months ago)
Hi Emmanuel, I'm sorry for my late reaction but my pc quit on me. This is a very hard question, some brute forcers go a little deeper and try it with HashCat, but I have no experience with that yet, so I cant help you further. I would just try to relive the moment you created the password, try to think about what you thought about at the time. If you want to try every combination possible I hope you got a big strong new pc, cause the searching time grows exponentially when adding an extra character. I really hope you get some clues soon about your password, because bitcoin is extremely well encrypted and very hard to hack, that is why it is worth so much. If just anybody could easily brute force a wallet, no one would keep thousands of dollars in btc. ;)

what option is used to tell it to try each token on the list x number of times?

You can find a very big tutorial at the official github of btcrecover https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md I hope this will help you a lot!

Ok I'll try to find out but is there anywhere I can find like standard token-lists and or good explanations or examples of the use of some of these options?

I actually don't know, I usually repeat the same token on different rows.

what if i cant rember any parts of the password? any suggestions

Hi mate, maybe you can find the information you need on this page, It uses pywallet.py as the extracting script. https://walletrecoveryservices.com/limited/

Bitcoin Daytrader hi Daytrader, do you know how to display the hash of the wallet file? I am trying to find the hash of the file i am trying to crack so i can use hashcat. Cheers Dude
Bitcoin Daytrader (10 months ago)
Hi GR, Thanks for using my tutorial, Yes you can use the wallet.dat file too, you can replace the .key file with the wallet.dat file. If you don't know anything about your password it is going to be a hard bruteforce, depending on the lenght of the password. You should check out the wildcard list for the token.txt file at https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md You will need something like:  %2i[0-9a-z] Where the number 2 is the amount of letters, be aware this could take a very long time for password longer than 6 characters
revonover (10 months ago)
how about the password is a phrase with space? put in some phrases in the token.txt? And i tried your method, i saw you use -no-eta -d command to unlimit time to match password, but where should i put in this command?
revonover (10 months ago)
thank you!! you are amazing! save my day!!
Bitcoin Daytrader (10 months ago)
after: C:\Python27\python btcrecover.py --wallet yourwallet.dat/.key/.wallet --tokenlist token.txt --no-eta -d
revonover (10 months ago)
thank you Daytrader!! will try it immediately! and -no-eta -d command, where should i put in?
Bitcoin Daytrader (10 months ago)
Hi Revonover, Thank you for checking out my video!! You can't put a space in a row of your token file, the program btcrecover would think that it is supposed to chose one of the words you put on one row. If you want to put a space in the token.txt you should use a wildcard, this is what represents a space: %s - a single space A percent sign with a small letter s, for more info on all the wildcards check the official tutorial:  https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md
TopSetupPL (10 months ago)

TopSetupPL (10 months ago)
What command to use to set a password length limit? thanks
Bitcoin Daytrader (10 months ago)
You can add a maximum amount of tokens with btcrecover.py --max-tokens 5 In this case it is only going to combine 5 tokens at max

Is there any way to limit ram usage? When it counts passwords it uses a lot of ram. 89m 400k uses about 16gb of ram :/

TopSetupPL (10 months ago)
thanks again :) you'll be rewarded ones i get what i lost ;)
Bitcoin Daytrader (10 months ago)
TopSetupPL, thank you for using my tutorial, you could try to skip it with --no-eta -d in the command, or try to work on your token.txt file

Litecoin is also currently worth a lot. and I have a lot of them. Is there a similar recovery program for LTC? I last logged in 5 years ago! So I have no idea of my passphrase
Bitcoin Daytrader (10 months ago)
Ross Williams, thank you for the view, you can use this programm too, just put your litecoin wallet in the command where I put a .key file, like this - - wallet wallet.dat and work on your token.txt file

Landan Jensen (10 months ago)
I have a 64 character random password, is there anyway to brute-force without a token list? Thanks.
Landan Jensen (10 months ago)
Bitcoin Daytrader damn, that's what I thought. Thanks anyways!
Bitcoin Daytrader (10 months ago)
64 character without a tokenlist is 100% impossible, you need a supercomputer to bruteforce a random 16 character within a year or 10, so 64 would maybe possible in the year 3000 since it takes the computer all characters ^64. Lets calculate it for fun.. There are 26 standard letters and 10 numbers, every letter could be a big letter so an other 26 characters, not thinking about Ó,ö,ä,!,@,#,$ kinda letters.. so that's 26+26+10= 62, so your computer is going to try: 62^64 = 62*62*62......*62*62 (64 times) = something with more than 100 zeros, my Texas Instruments TI-83 calculator could not even calculate the exact number. It stopped at 62^55=3.8 *10^98 which means a 3 with 98 zeros, My pc takes half a hour for one million tries. So for a 55 character random password without a token it would take my pc, 1,5*10^92 hours... that's 150.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000 Hours that's still a Gazillion years XD

This is amazing bro :) now how to use it to recover my second password? how to direct it to just brutefoce the second password? I double encrypted my wallet and now i have totally no idea what my second password was coz i was too dumb not to write it down as i did with my main password and now to my surprise i'm screwed by me. Totally dumb, shit happens. Thank god i found your amazing tutorials that would really help people having this problem like me. Hope to hear some advice from you bro:) thanks:)
Bitcoin Magnet (10 months ago)
Thanks a lot man :) i will try this :)
Bitcoin Daytrader (10 months ago)
Hi man, in your case you can use the btcrecover tool, if you start the program with your tokenlist and wallet in the argument it will search for your first blockchain.info password (btcrecover.py --wallet wallet.aes.json --tokenlist token.txt), you just have to add the argument --blockchain-secondpass to search for the second password, but you need to enter the first password (it wil ask you when you run btcrecover) So if you have python2.7 and all the extra's for btcrecover running on your pc and have an idea what you password could be, make the tokenfile and try it out.. It would be awesome, if you find it back ;)
Bitcoin Magnet (10 months ago)
Thanks for your response Bitcoin Daytrader :) Yes the blockchain.info wallet and i have the wallet.aes.json backup file i downloaded with the python script from blockchain.info. Would love to see that upcoming tutorial of yours :) what would i do? do i have to brute-force it offline?(since i have the back up file) or just the online brute-force? in my case which method would you suggest? thanks man :)
Bitcoin Daytrader (10 months ago)
Hey Bitcoin Magnet, thanks for you view. What kind of wallet are you using? Today I have recorded a couple of new tutorials, one of which is on how to brute-force the second password of the online blockchain.info wallet using btcrecover. I will need to edit this video first so expect that to be online within a week. Regards

I installed everything up to this point. I am trying to recover 2 words from my 12 word seed phrase from my electrum wallet. I have the first 8 words in the correct order as well as the last 2 words. I am just missing 2 words in between. How would I do this using the electrum seed word list? other than knowing 10 of the 12 seed words, I just have the public address.
Grace Love (4 months ago)
Bitcoin Daytrader please what is your email address so I can write to you please
Ayrat Bulatov (8 months ago)
You can use The Grideon BITCOIN PASSWORD RECOVERY tool for that. Just use mask option to separate your pass into 3 parts. 1st and 3rd parts will have only one set of words you already know, and the middle is up to you (you can put a dictionary in there or setup any rules for the search).
Brian Kaspiev (10 months ago)
that would be awesome
Bitcoin Daytrader (10 months ago)
Hey Naturally Baby, I have not been in the same situation yet, so I can't give you a straight answer right away, but I am almost certain that it can be done using btcrecover. I need to get in to your problem first and try to replicate your situation here with an new wallet. This will be one of the projects for this week. When I have found a solution I will let you know. Regards
Dancing Dragon (10 months ago)
I was wondering can you do this online? I dont have a download file as the wallet is based online.
Bitcoin Daytrader (10 months ago)
Hey Dancing Dragon, It depends on the online wallet. I do know how to do that for blockchain.info wallets, a new tutorial on that topic is going to be uploaded next week but for other online wallets I think you would have to write the brute-force script yourself in php or python.
C K (10 months ago)
Hi, I used your tutorial and managed to figure out the password, but in fact the problem is another. lol Do you know how to solve this problem? file: wallet / crypter.cpp, line 198
C K (10 months ago)
Thanks, but problem continues even with -salvagewallet
Bitcoin Daytrader (10 months ago)
Hey Leo Kawata, If you want to salvage your wallet you have to run the bitcoin core in CMD. Copy your backup to a safe place in case it wont work. Open CMD and type: cd C:\Program Files\Bitcoin this brings you to the bitcoin directory (if you installed it in program files ofcourse) Then you run bitcoin core with the salvage option by typing: bitcoin-qt -salvagewallet If you don't add the salvage line, the wallet just starts normaly. With the -salvagewallet argument the wallet resets. I hope this helps you out my friend Regards
Bitcoin Daytrader (10 months ago)
Not yet, never had to use it, but I could try ofcourse.
C K (10 months ago)
Bitcoin Daytrader the backups must have a problem in the encryption, because when I type the password to see the private key the same message appears. Do you know how to used commands line? -salvagewallet?
Bitcoin Daytrader (10 months ago)
Hey Leo, I've been searching and found a possible solution for you, you only need your bitcoin core wallet passphrase. You need to know the btc address you want the private key from, check your transactions. Then you need to go in the top of bitcoincore click Help\Debugscreen\Console In the console you can type commands. First type: walletpassphrase YOURPASSWORD 600 (the 600 is the amount of seconds your wallet is open in the console 600sec=10min) if it is all ok you will get a response NULL Then you type: dumpprivkey YOURWALLETADDRESS Repeat this for more addresses You could use the private keys in a other wallet that can import privatekeys. I hope this will help you to get your access back. Regards

Hello Bitcoin Daytrader, Thanks for the awesome tutorials. I am having the exact same error as Thiago Mesquita, No such file or directory: 'token.txt' I have however, created my token.txt file with my notepad and saved it in the btcrecover-master folder. I dont understand what I'm missing. I followed every step to the letter and keep getting the same error. Any help would be appreciated, keep up the awesome videos. Cheers
Bitcoin Daytrader (10 months ago)
Hi Thiago, It seems that you did not create a token file yet. You can do this by opening a new notepad, write some tokens down (part of the password you remember) and save the notepad file as token.txt in the btcrecover-master folder. Hope this helps you out. R egards
i want to see these steps using wallet.dat for altcoins.

Hey, how do i create a tokenlist with letters like #,@ . eg [email protected] but i am not sure which alphanumeric was used in the password.
Bitcoin Daytrader (11 months ago)
If you place the ^ sign in front of Spirtit in the token.txt file it tries combinations starting with that word, but for a full list of wildcards I suggest reading the manual. You can find that here https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md
SPORTS GALLERY (11 months ago)
the Last Alphabet am Not sure if it is @ or $ or #. Which widecard do i use there?? any idea. Greets
Bitcoin Daytrader (11 months ago)
Hey Sport Gallery, have you tried putting the alphanumeric in the typo.txt file or maybe you can put them on separate rows in your token.txt file like Spirit, (enter) # (enter) @ I hope this can help you out. Greets

Bitcoin Daytrader (11 months ago)
I'm sorry Sefa, but I have not used electrum litecoin wallet yet, so I don't know how to export you private keys. Does the wallet work with BIP-32 Mnemonic Code? (the 12 word phrase) If so you need to convert the 12 words to wallet addresses and public/private keys.
mikey (11 months ago)
Hey, i need help with exporting my private key from multibit classic to electrum. I havent touched my btc for years and having checked it recently i am now aware that multibit is no longer supported. https://www.youtube.com/watch?v=LaijbTcxsv8 They provide this video on how to export the private key but they say not to password protect it? Is it safe to do it like this ? as im not sure why they dont say you should password protect the private key? would appreciate your help!! thanks man
mikey (11 months ago)
Thanks a lot for your help!
Bitcoin Daytrader (11 months ago)
Hi Michael, The reason you password protect the export of the private keys for a personal backup is to ensure you can not read the file created if you open it in any text editing program like notepad. Try it!! (for instance richtclick on you exported privatekey file and open with Notepad) In your case it is different, you want to know the privatekey. So dont password protect it, safe the file, open it, use it on your new electrum wallet and if it works be sure to delete your exported privatekey from the computer. The tutorial you showed me is a good one! :D And for your own safety NEVER USE PUBLIC COMPUTERS when working with private keys.
