public class ECSecretBCPGKey

extends BCPGObject

implements BCPGKey

Base class for an EC Secret Key. This type is for use with PublicKeyAlgorithmTags.ECDH or PublicKeyAlgorithmTags.ECDSA. The specific curve is identified by providing an OID. Regarding X25519, X448, consider the following: ECDH keys using curve448 are unspecified. ECDH secret keys using curve25519 use big-endian MPI encoding, contrary to X25519SecretBCPGKey which uses native encoding. Modern implementations use dedicated key types X25519SecretBCPGKey, X448SecretBCPGKey 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, X25519SecretBCPGKey or X448SecretBCPGKey MUST be used for X25519, X448.
