public Class ECDHPublicBCPGKey

Class Inheritance

Imports

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.
