Someone know how more easy ?

[COBRAS]

Good day.

Someone know how to find privkey more easy at curve with k not k = 7, but with any other k , for ex k = 1, k= 2, k =.... n ?


Thank you

Finding a private key of a given address is like finding an atom in the universe by which I mean it's impossible.

If it is possible, Bitcoin blockchain is useless and very risky to use, hence I believe nobody will have belief in Bitcoin and use it to store money.

Combinations of Bitcoin private keys is 10⁷⁷ and the universe has 10⁸⁰ atoms. You can not find an atom in the universe so neither find a Bitcoin private key to hijack a wallet of someone else.

Idea from this code of Krashfire, but hi not on connection now...

Looks like hi find something for change points order

Krashfire finds something what looks like a privatekeys in subgroups, but code need to be  midified and verified.


Output reult of his sceypt:

(privkey,order), (privkey,order)....


Partial private keys for {name}
[(0, 3), (6, 13), (1502, 3319), (8892, 22639)]
-------------------------------------------------


so for reconstruct final privkey need additional work, but, I think he is MAKE INTERESTING SCRYPT,I try to do the same with subgroups, but I take any privkeys..... Many thanks Krashfire for his scrypt


So, have someone any ideas how to modify Krashfire scrypt for take result ?
