I have a 2013-2014 240-byte wallet backup file from Bitcoin Wallet (by )Andreas Schildbach). I generated the passphrase using a pattern of two English proper nouns and 1-2 numbers.

I cannot positively say I know the proper nouns, or the capitalization. I do not know the overall length. am not positive the numbers are adjacent in the passphrase.

I am aware of Hashcat generally, and have done basic attacks on this passphrase using my best guess wordlist and standard wordlists. What are some more advanced technique ideas I can apply to this?

the chance is very low. unless you have clues. brute force is not a way to get back your password. the time cost is very high. if you have many btc in the wallet. then you can try it. but the chance is too low.

  • @ndemarco we have the tool to do that work. but the chance is very low if you don't have any clues. impossible without clues. i guess you even don't know how many btc in the backup. maybe empty after you recovered. – btc2doge Apr 5 at 13:12
  • just checked. if you have clues. hints. we have a high chance to get back your coin. the document is not a key. it is a encrypted backup. need do decryption first. it takes time. just helped another guy on this same backup. she has hints. so did not take much time. – btc2doge Apr 6 at 14:29
