Hello
Can you write a random point example? I didn't understand.
Can you write a random point example? I didn't understand.
With that attack we can easily recover any private key.
i am run this code output

can you explain how to recover private key.
If we can do this with fixed real public key we can recover private key,
give me example value and code ,recover private key
Target point is
G = E(0x79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798, 0x483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47d08ffb10d4b8)
X = 0x79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798
Y = 0x483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47d08ffb10d4b8
what is a priv of you secp257k1 loint ?
what is a benefit of this "attack"?
It can recover private key for 10 - 15 minutes.
