I have a question and why two different private keys can lead to the same address in certain circumstances?
Example:000000000000000000000000000000000000000000000050574a424748444e47
fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88
1ECDtqs8nAUyxNuTY4kTV6rHr6NoVUkMna
s= fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88
N = 115792089237316195423570985008687907852837564279074904382605163141518161494337
because s being larger than the order of the curve N they are equivalent to the same private key.
r= fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88 % N
r= 000000000000000000000000000000000000000000000050574a424748444e47
r = s
In answer to your question, I have to do a study in the elliptical curve that I may have made it easier to make some key encryption calculations, and one of those things is to calculate the private key address, and to calculate the private key and to calculate the number. Say, did I calculate correctly?
