WebApr 4, 2024 · type PublicKey. PublicKey is an ECDH public key, usually a peer's ECDH share sent over the wire. These keys can be parsed with crypto/x509.ParsePKIXPublicKey and encoded with crypto/x509.MarshalPKIXPublicKey. For NIST curves, they then need to be converted with crypto/ecdsa.PublicKey.ECDH after parsing. WebECDH is used for the purposes of key agreement. Suppose two people, Alice and Bob, wish to exchange a secret key with each other. Alice will generate a private key d A and a public key Q A =d A G (where G is the generator for the curve). Similarly Bob has his private key d B and a public key Q B =d B G.
