WebMar 18, 2024 · When we generate an EC public/private key pair, we pick a number x and compute the elliptic curve point x G, which is G (the well-known "generator point") added to itself x times. The public key is the point x G; because it is a point, we need to state whether we're expressing that point in compressed or uncompressed format. WebWhat they mean is not that some curves are inherently unsafe, but that safe implementation of some curves is easier than for others (e.g. with regards to library behaviour when it …
