Webb18 mars 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. Webb10 mars 2024 · The encoding of the private key consist of a SEQUENCE with many elements; trying to parse that as point is of course nonsense. removeSignByte is also not complete: the coordinates x and y could also be smaller than 32 bytes (try and look up I2OSP function also used for RSA).
