I have a basic question regarding the understanding of EC cryptography:
As far as I understand the n is the private key in EC (how many times you add the starting point to itself).
Taken from this site (https://blog.z.cash/pairing-cryptography-in-rust/) "Alice multiplies Bob’s public key by her (scalar) private key, and vice versa, to find a shared secret in the presence of an eavesdropper."
So if n is a 256 bit sized number I would have to add the point like 10 ** 77 times to itself. Even if one calculation takes only nanosecond in total this would take 10**50 times of the age of the univ…
