I was playing with the constants related to the implementation of endomorphism on the secp256k1 curve, and through strange manipulations, I was able to derive LAMBDA and LAMBDA^2 from B1 and B2. I am not familiar with the original document, so this was a bit of a discovery for me. But overall, there's probably nothing useful here.

We turn the integer variable into a binary format, add a bit in front, remove a bit in the back, and convert back to an integer variable.
def int_to_binary_with_fixed_length(n, length):
binary_repr = format(n, f"0{length}b")
return binary_repr

Я попросил chatGPT написать код для получения публичного ключа из приватного ключа. Она написала. Вот и все, в принципе.

Many people know how to get a private key from a nonce. But I did not find information on how to get a nonce from a private key. If someone also does not know how to search, then here is a ready-made solution. And here is what I took as a basis: https://asecuritysite.com/ecdsa/ecd3
import ecdsa
import random
import libnum
import hashlib
G = ecdsa.SECP256k1.generator
ORDER = G.order()
