Class ECDHPublicBCPGKey

java.lang.Object

org.bouncycastle.bcpg.BCPGObject

org.bouncycastle.bcpg.ECPublicBCPGKey

org.bouncycastle.bcpg.ECDHPublicBCPGKey

All Implemented Interfaces:

BCPGKey, org.bouncycastle.util.Encodable

public class ECDHPublicBCPGKey
extends ECPublicBCPGKey

Base class for an ECDH Public Key. This type is for use with PublicKeyAlgorithmTags.ECDH. The specific curve is identified by providing an OID. Regarding X25519, X448, consider the following: Modern implementations use dedicated key types X25519PublicBCPGKey, X448PublicBCPGKey along with dedicated algorithm tags PublicKeyAlgorithmTags.X25519, PublicKeyAlgorithmTags.X448. If you want to be compatible with legacy applications however, you should use this class instead. Note though, that for v6 keys, X25519PublicBCPGKey or X448PublicBCPGKey MUST be used for X25519, X448.
