Status: Exhausted Bitcoin Wallet Passphrase Recovery

[suhel1986]

HI,

I tried following command, It started cracking Bitcoin Wallet Passphrase and status came: Exhausted

C:\Users\wq\Desktop\hashcat-4.1.0>hashcat64.exe -a 3 -m 11300 wallethash.txt ?a?a?a

I tried on 2 different wallets and got the same result.

This what came up in orange when started in CMD;

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework

Approaching final keyspace - workload adjusted.

Cracking performance lower than expected?

* Append -w 3 to the commandline.
  This can cause your screen to lag.
* Update your OpenCL runtime / driver the right way:

* Create more work items to make use of your parallelization power:

Driver temperature threshold met on GPU #3. Expect reduced performance.

I would like to know what am I doing wrong in here,

Many Thanks

you are guessing a password of 3 'characters' long. That's only 857375 passwords (kind of like aaa until ~~~). You can guess 1115 hashes per second so in 12 minutes you tried all 3 characters and none were the correct password.

You are the Champion.  I will try more.

God Bless you.

Sorry mate I am not so good at this one, now I got following error,

I guessed if the password was 10 to 15 char long I used following command and I got this error



Integer overflow detected in keyspace of mask: ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?

I you can correct my error with examples and educate me, that will be so helpful

You are trying 10 to 15 char, that is waaaaaayyyyyyyyy too long. You are never gonna get that.

A length of 10 generates a total of 95 (characters in ?a) to the power of 10 possibilities. In total 59873693923837890625 passwords. At your speed of 1115 H/s that will take 1702764467 years.

You can't brute force a Bitcoin Wallet Passphrase letter for letter. You need to use https://hashcat.net/wiki/doku.php?id=dictionary_attack which combines your words in the Passphrase. Only problem there is you need a wordlist which has all the words in the passphrase and isn't too long. otherwise you will run in to the same problem.

Our solar system would come to an end before you would crack it with that mask.
I recommend utilizing different method.

Bitcoin wallet & 15 chars is not doable in a human life.

By the way your problem is the last '?' character, remove it :

C:\Users\wq\Desktop\hashcat-4.1.0>hashcat64.exe -a 3 -m 11300 wallethash.txt ?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?a?

Finally hashcat-4.1.0 is outdated. Use v5.1.0

Does that mean using Hashcat's Brut Force is Impossible on Bitcoin,

Because this is the minimum estimated time:
