Sm2 invalid point encoding 48

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.

That means that, as you read bytes that are encoded with BER, first you encounter a type, called in ASN.1 a tag. This is a byte, or series of bytes, that tells you what type of thing is encoded: an INTEGER, or a UTF8String, or a structure, or whatever else.
