What exactly is the output? #191

thanks for this program by the way! I've ran this a few times, and when I use a wordlist like so: $brainflayer -v -b btc.blf -i wordlist.txt, I get a 40 character long address (I think), then a word. but, how is this cracking anything? Wouldn't I need the private key? is the 40 character output a private key or an address or? Plus, aren't the wallet word lists 12 words long?

Plus, I did try just the incremental method : $brainflayer -c e -v -b eth.blf -I 0000000000000000000000000000000000000000000000000000000000000001 , and I get different results that seem to show an Ethereum address, then supposedly a private key so Addressxxxxxxxxxxxxxxxxx : PrivateKeyxxxxxxxxxxxxxxxxxxxxxxxx
, but all of them are false positives, so zero balance, and the address was never used it looks like? so, I'm not 100% sure what I'm looking at, or what other steps I need to take to run it properly? I'm using ubuntu 22.04 or thereabouts.
I get no errors compiling and running,

Thanks!

you should know this. easy question. I'm questioning whether this produces useful information or not?

ryancdotorg commented 6 months ago

I don't appreciate your tone.

try ctrl-f "false positive" on the readme

IntrinsicInnovation commented 6 months ago

lol, why am I getting ethereum addresses? is it supposed to do that, or what is wrong with my parameters?

ryancdotorg commented 6 months ago

false positives are addressed in the readme

brainflayer outputs 160 bit values used as internal representation of addresses by many cryptocurrencies, along with the matching input. as a deliberate design decision, it does not output private keys unless private keys were the input

ok, thanks, sorry for that. Also, when I type it in in blockchain.com it just says ether addresses. still not 100% clear on that, as in blockchain.com it says its ether. I do get a private key too, but doesn't seem to relate to address? tried as a bitcoin address and it's always 0 balance.
