If your goal is detect password and if u accept bruteforce method yes ; i can proof it.
Then why don't you post it here so everyone knows you are not just talking?
alas, he can't do it.
Guys calm down, im waiting rockyou.txt
Edit : seed is already avaible in unencrpyted wallet, i mean no need to money transfer etc, its just password challange.
Edit2 : i tried opencl with 7 gpu bruteforce ; 1024 iteration sha512 decrypt not efficient even if opencl. Also password not in the rockyou.txt list.
I've made a random password similar to something like this: KdR.72.G@$.1eeFug.1@#s!
Just something random that you will never find in any password lists or anything, so don't even try to find it, you'll just lose your time, the whole point was to find someone capable of retrieving the password from the encrypted and decrypted file, not to bruteforce it cause it was pointless.
Again as outlined earlier by other bt members "known plaintext attacks" are not possible
I have looked at the amount again and it's laughing at me back with an evil smile, and I can never access it. I guess it's the power of encryption and the universe.
I am thinking of bruteforcing it more and more, probably the length of the password is not that high, who knows, but I don't have the tools or computers required for the job, might be a dead end eventually.
LATER EDIT: THE PASSWORD TO THE PUZZLE WAS: AFS.ss4.19doEE1!wt1
One can easily verify, but since no one posted it or messaged it to me, I find this lead a dead end. I will go the bruteforce way
You cannot, If the password is anything close to 10+ characters you will not make it in lifetine with todays speed of computers.

Are you referring to the BIP39 passphrase? or the wallet password?
