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. Webb20 okt. 2016 · Java's default encoding for a PublicKey is "X.509" which is not just the EC point; it is an ASN.1 structure identifying the algorithm (EC) and parameters (here prime256v1) PLUS a BIT STRING wrapping the point; see rfc5280 section 4.2.1.7 and rfc3279 section 2.3.5.. Similarly the default encoding for PrivateKey is "PKCS#8" …
