<n​ever_ever_quit:matrix.org> would anyone know how to extract a hash from FEATHER wallet .keys file?

<n​ever_ever_quit:matrix.org> lost a good amount - and don't have the seed (i accidentally deleted text file i stored all my info in)

<n​ever_ever_quit:matrix.org> i have the keys file. so technically, if i can somehow figure out the password i could still access the funds.

<n​ever_ever_quit:matrix.org> however, the password is 20+ character, random characters, letters, numbers.

<n​ever_ever_quit:matrix.org> was thinking of trying to use HASHCAT to brute force it.

the keys there are derived via Cryptonight V0

I don't think you would get there with 20+ characters

<n​ever_ever_quit:matrix.org> probably not, heh.

<n​ever_ever_quit:matrix.org> ...but maybe good to keep the long game in mind on this one.

<n​ever_ever_quit:matrix.org> any idea on how to extract it?

<n​ever_ever_quit:matrix.org> probably not, heh.

<n​ever_ever_quit:matrix.org> my expectations are low.

<n​ever_ever_quit:matrix.org> ...but maybe good to keep the long game in mind on this one.

<n​ever_ever_quit:matrix.org> any idea on how to extract it?

<r​brunner7:monero.social> IMO you probably need a custom-written program for brute-forcing it. First, the encryption algorithm of the file is proprietary, and the check "Success, this is the correct password" is also highly specific - you would need to check for some characteristic bytes that a Monero wallet file *in particular* has to decide whether decryption succeeded. And as DataHoarder already said, w<clipped message>

<r​brunner7:monero.social> ith a fully random 20 character password probably forget it, for runtime alone.

yeah. I implemented the decryption/check and it also depends on ... version it was created

<r​brunner7:monero.social> I mean, frankly, we want to be it almost impossible, right?

<r​brunner7:monero.social> If anybody can just lift off Monero wallet files with a trojan and then sprinkle a bit of HASHCAT over it to open, that would be in dire need of improvement.

should use RandomX for derivation nowadays :)

there are Cryptonight ASIC after all

specially V0

"and don't have the seed (i accidentally deleted text file i stored all my info in)"

don't wallets tell you to write down your seed on a piece of paper :P

i mean the official program really tries to make you write down your seed

<n​ever_ever_quit:matrix.org> figured as much. this happened a while ago so every once in a while i check in on new possibilities of maybe one day being able to unlock it.

<n​ever_ever_quit:matrix.org> recent recommendation was attempting with something like Haschat,

<n​ever_ever_quit:matrix.org> but also continuously imagining something custom to give it a shot with.

<n​ever_ever_quit:matrix.org> as tech evolves, maybe one day it could be possible.

<n​ever_ever_quit:matrix.org> older version, probably mid/late 2023ish.

never_ever_quit: if it's just uppercase and lowercase and numbers

the number of possibilities would be 62 ^ 20

<n​ever_ever_quit:matrix.org> nah, that actually would've been safer, haha.

<n​ever_ever_quit:matrix.org> was working w/ encrypted textfile in sandboxed environment.

<n​ever_ever_quit:matrix.org> had just done some wallet consolidating,

<n​ever_ever_quit:matrix.org> created new wallet/seed for storage of the funds, wrote fresh seed/pw in a new file.

<n​ever_ever_quit:matrix.org> boom. txt file was obliterated accidentally when my laptop ran out of bat and hadn't saved it.

<n​ever_ever_quit:matrix.org> usually always have backups otherwise.

<n​ever_ever_quit:matrix.org> big mistake.

62 ^ 20 = 704,423,425,546,998,022,968,330,264,616,370,176

number of possiblities

if it's really fully random, then it would be much much higher than that

<n​ever_ever_quit:matrix.org> yeah, was a mix of everything.

<n​ever_ever_quit:matrix.org> uppercase/lowercase letters, numbers, special characters etc. heh

<n​ever_ever_quit:matrix.org> the only thing i could maybe provide is a rendition of the 'style/gesture' of my key presses.

<n​ever_ever_quit:matrix.org> i notice that many of the pw's i would make for wallets around that time (which there were many), would share some similarities.

<n​ever_ever_quit:matrix.org> buy beyond that, nothing really. no keywords for potential bruteforce.

<n​ever_ever_quit:matrix.org> maybe one to save for a quantum era.

well, yeah you're fucked

nah quantum is only good for key exchanges

quantum can factorize very large numbers easily

but it cannot bruteforce a password

infact, it'd be much slower than a traditional computer at that task

<n​ever_ever_quit:matrix.org> there's several pw i created from that era that have similar starting 3-4 characters.

<n​ever_ever_quit:matrix.org> would chances increase enough to make it worth a try if I was able to piece together a string of sequential characters?

<n​ever_ever_quit:matrix.org> no guarantee that this one had exact same structure,

<n​ever_ever_quit:matrix.org> but there is small possibility and amount is sizeable enough that i'd like to exhaust any options.
