Modified Lattice Attack Script

I tweaked the gen_data.py script found at this GitHub repo: https://github.com/bitlogik/lattice-attack. Now, whenever you generate sets of R,S,Z(HASH) Signatures, you can see the K_Nonce value used. Just a heads up, it doesn't show up in the json file like the other data; you'll see it directly in the Terminal. The full modified code is below. Make sure to enter your own public keys' XY coordinates in gen_data.py. I also updated ecdsa_lib.py to include a print function for the K_Nonce. With R,S,Z(HASH) and now K nonce out in the open, you can head over here and plug in your data: https://rawcdn.githack.com/nlitsme/bitcoinexplainer/aa50e86e8c72c04a7986f5f7c43bc2f98df94107/ecdsacrack.html to find the Private key. With this info, you’re pretty close to getting the private key. Best of luck!

Hi there,  This is interesting, but is not quite working for me. After I generate the json file, once I run the lattice.py I get this error: Loading data from file data7.json Public key data invalid, not on the given SECP256K1 curve. I think it has to do with the format that the xY coordinates I am putting in is not correct. My question it, where and how you get this XY ( or RS) coordinates from, so that they are in the right format to go in gendata.py? Thanks for your input

KRASH Can you add calculation of privkey to scrypt? pvk = (inv(r) *  ( (k*s)-z )    ) % N

I have added those definitions but I get an error. Is that the right part of the code on the lattice_attack.py for them to go in? THANKS. mahuro@machine1:~/lattice-attack$ python3 lattice_attack.py -f data7.json   File "/home/mahuro/lattice-attack/lattice_attack.py", line 41     r * pvk = (  (k*s)-z )  % N     ^^^^^^^ SyntaxError: cannot assign to expression here. Maybe you meant '==' instead of '='?

Not sure where in the code should it go the definitions you mentioned. I get another error, but I think I am closer now. I think I simply need to change of private_value to integer, But I am not sure how. There is a comment in the lattice_attack.py that says how to convert between integer and hex, but it doesnt say where those given equations should go: # To convert to integer : # if got bytes use : int.from_bytes(bytesvar, bytesorder="big") # if got hex use : int(hexintvar, 16) # Has anyone got this to actually work? just curious...

krossfire know kode, he can do it

theres no point running this. as the rsz created will not point to the correct private key or public key. ran it a long time ago.
