Walletwasabi: I forgot my password, just remember the mnemonics, can I still retrieve bitcoin?

I forgot my password, just remember the mnemonics, can I still retrieve bitcoin?

[suisuiyiyi]

Is there a python program that cracks passwords? Or can someone say the encryption rules? I remember part of the password. I hope I can crack it through my own dictionary.

[MaxHillebrand]

Unfortunately no, without the password it is impossible to generate the private key to spend your bitcoin, you need BOTH the mnemonic and password.
But, there is a password finder command line tool that does a brute force "attack" on your wallet to guess the password. Check it out, I hope it helps.

I tried this and could not find the password. T_T

[suisuiyiyi]

Can someone say the encryption rules? I am losing a lot. I have to retrieve my bitcoin. 😢

[suisuiyiyi]

I sorted out hundreds of passwords I might use, but I don't know how to automate the tests.

[MaxHillebrand]

Check out the documentation of the password finder, here it says to run the command $ wassabee run help findpassword with the flags if you have included -n numbers and -x special characters. For example, $ wassabee findpassword -n --wallet:MagicalCryptoWallet

However, if you have a password longer than 8 digits or so, then it will take a very long time until your computer might find it.

[MaxHillebrand]

I'm not sure if there is an automated way of checking the password with a set word list...
So, either run the password finder, or manually type in the passwords from your list in the GUI.

@suisuiyiyi if you know the mnemonics and you have a set of possible passwords then you can recover your bitcoins. Take a look at the KeyManager::Recover method https://github.com/zkSNACKs/WalletWasabi/blob/30c2d613f3e48c22ef465b67969ad740be369d0c/WalletWasabi/KeyManagement/KeyManager.cs#L166

Take into account that it is infeasible to bruteforce a password so, if you really have no idea what your password is the you cannot recover the wallet. Here you have the encryption spec, but i am think it will not be useful for you.

Just to be clear, @suisuiyiyi do you still have your wallet file?

Yes I have.

Thank you for your help.
I will not give up recover my bitcoin in the future. T_T(Crying)

[suisuiyiyi]

I created a python program that automatically tries passwords.
I hope I can find my lost password. Crying

[nopara73]

Just to be clear, @suisuiyiyi do you still have your wallet file?

Yes I have.

So password finder bruteforcish tactic has the most chances. Messing with recovery magic would be counterproductive.

[kravens]

@suisuiyiyi To speed up the ''brute-force'' finding, you could try to parallel compute the xpub on a strong GPU for different passwords until you match the xpub in the Wasabi-wallet.json file! See pycuda or pyopencl.

Yes, the CPU is too slow.
I don't understand Bitcoin algorithms, I need to take the time to learn.

My password may be a bit long. Crying

[suisuiyiyi]

I use my program to find the password. I will write a blog later, hoping to help people who have lost their passwords like me.

Happy to hear that!

[thggar]

@lontivero Are you able to give a quick explanation on how to run Keymanager Recover?

I know my mnemonics and have and have a set of possible password variations but so far unable to get KeyManager::Recovery to run.

Your help would be greatly appreciated!!

[suisuiyiyi]

@ec4hunnid Do you still have your wallet file?

[thggar]

@suisuiyiyi I dont :/

Only have seed words, very likely set of password variations, addressmanagermain.dat, wallettransactions.json, and well a very corrupted original wallet file.

The corrupted wallet file contains a bunch of random firefox data so i think it is at the point of no return in terms of being able to fully recover and use your Bip38BruteForcer on it.

[suisuiyiyi]

@ec4hunnid I think the first you should look for the EncryptedSecret value in the file which you have.
Maybe you can try the file recovery program.

[nopara73]

Yes, it's hard enough to find a typo when the correct or incorrect combination can be validated against an encrypted secret. Without this it's nearly impossible: https://github.com/zkSNACKs/WalletWasabi/issues/1356

There's this service that's being recommended on Reddit a lot, so you may want to try it: https://walletrecoveryservices.com/

[thggar]

Shoot!
Ive checked all files that were recovered using file recovery program yet none contain the encrypted secret.

Unless there is a way to use mnemonics and password variations as @lontivero mentioned I guess the only other option would be to give walletrecoveryservices.com a try.

If do appreciate the input tho guys! If anyone else else has a suggestion im all ears

[suisuiyiyi]

Write a program, use the mnemonics and all possible passwords to generate wallet and verify it if bitcoin in it......

[nopara73]

One more thing that may help. @ec4hunnid there's a wallet backups folder. You may find your correct wallet there. Or if you ever renamed your wallet file, you will definitely find your correct wallet there with the old name.

[suisuiyiyi]

@ec4hunnid .walletwasabi/client/WalletBackups/

Try to recover and find all the json files in your system.

[thggar]

Never renamed it. And actually the only way I found the ANY copy of the wallet was using a file recovery tool which after 16 hours dug up the corrupt backup from walletwasabi/client/WalletBackups. At this point ive generated over 100 recovery wallets by hand hoping to get my password correct and have had no success.

[suisuiyiyi]

@ec4hunnid The wallet file not only in .walletwasabi/client/WalletBackups, but also in .walletwasabi/client/Wallets.

You should try to repair the corrupt backup file.

[lontivero]

@ec4hunnid if you have your mnemonics then you do not need your wallet file. What you need is: (your mnemonics) + (a list of passwords) + (one of your wallet addresses).

Using the NBitcoin library you can do something like this (pseudo code):

mnemonics = Mnemonic("your words go here ...")
foreach pwd in list_of_passwords:
    ek = mnemonics.DeriveExtKey(pwd)
    epk = ek.Derive("m/84'/0'/0'/0").Neuter()
    addr = epk.PubKey.GetSegwitAddress(Network.Main) 
    if addr == "bc1q.....": // my first address
         print "Eureka! My password is {pwd}"
         break

[thggar]

@lontivero Thank You for your reply! I have all those (mnemonics, list of passwords, and my wallet addresses)

I will give this a try now. Assuming this code would be added to the Program.cs file and then ran?

[lontivero]

That's pseudo-code, that means it is not valid c# code and will not compile. However, it should be very easy to make it valid c# code and make it compile.

[thggar]

(Example)

mnemonics = Mnemonic("sand water ice left right south north east west sail boat coin")
foreach pwd in list_of_passwords:
ek = mnemonics.DeriveExtKey(pwd)
epk = ek.Derive("m/84'/0'/0'/0").Neuter()
addr = epk.PubKey.GetSegwitAddress(Network.Main)
if addr == "bc1qsmr7uprqfgnfkxm0xek86znhf4efykwzmjpjz9": // my first address
print "Bit_Coin Wassup--B Testing3Password b!keride"
break

Researching coding on blockchain now will update as I progress.

[suisuiyiyi]

@ec4hunnid I have a lot of work to do recently. Don't worry about this.
I will try to help you when I have more free time.
