Title: hash bitcoin NEED HELP FOR RECOVERING OLD WALLET
Post by: EdouardDuval on August 29, 2022, 12:16:47 PM
Hi everyone, hope you doing well.
My question is, is there another software than hashcat for resolving this kind of hash?
$bitcoin$64$xxxxxx$16$0af493ab2796f208$99974$2$00$2$00
Thanks you for your help.

Why do not you want to use hashcat? It seems to have the best performance for your needs.

The other options are John the Ripper (https://github.com/openwall/john, https://www.openwall.com/john/) and btcRecover (https://btcrecover.readthedocs.io/en/latest/). If you want to use CPU only, it will be very slow, if you have GPU available, follow instruction how to enable it in btcrecover (https://btcrecover.readthedocs.io/en/latest/GPU_Acceleration/#btcrecover-gpu-acceleration-guide)

All depends if you have any clues, what the password is. If you know nothing, even length, it is very difficult and the most probably not worth to do it.
If you have any knowledge about password, you should thing what are you sure about and what is doubtful. For example you may be sure that length is 10 characters, or you may think it might be 8-12 characters.
Then think if you build your password from a "real" words, sentences or numbers. Was there any "template" of passwords you used in the past (like name + number)? What mistake was done? uppercase/lowercase, typo etc.

But if all you know is that - for example - it was 16 random characters, it does not seem to be doable...

In general there are 2 options:
1) you use dictionary, for example from leaked passwords etc. And you may add some rules which would convert input into several outputs (for example it takes password "Jessica" and produces Jessica1, Jessica2 etc.
2) you use pure brute-force, which is doable for passwords 7-8 characters long. And of course you may think about charset (language) - did you use plain text, or accented characters or Japanese?

If you have set a custom password then dictionary is not going to be useful for you. The dictionary is only meant for people who have set a very weak password so that it can be cracked instantly.

You should stick with token lists, but instead of adding stuff to the end of the password, try to replace some words with others, do number and special characters substitution and concatenation.

Hi everyone, hope you doing well.
My question is, is there another software than hashcat for resolving this kind of hash?
$bitcoin$64$xxxxxx$16$0af493ab2796f208$99974$2$00$2$00

Is it your wallet or found/bought online?
End of extracted hash is like in some forged wallets offered for sale:

Yes, knowing hash it is only possible to find password. But at the end it is just a "word", you cannot do anything with it without wallet.dat file.
