The Bouncy Castle Java APIs for the OpenPGP Protocol. The APIs are designed primarily to be used in conjunction with the BC LTS provider but may also be used with other providers providing cryptographic services.

The newest version!

/**
 * Base class for an EdDSA Public Key.
 * Here, the curve is identified by an OID and the key is MPI encoded.
 * This class is used with {@link PublicKeyAlgorithmTags#EDDSA_LEGACY} only and MUST NOT be used with v6 keys.
 * Modern OpenPGP uses dedicated key types:
 * For {@link PublicKeyAlgorithmTags#Ed25519} see {@link Ed25519PublicBCPGKey} instead.
 * For {@link PublicKeyAlgorithmTags#Ed448} see {@link Ed448PublicBCPGKey} instead.
 * @see 
 *     OpenPGP - Algorithm-Specific Parts for EdDSALegacy Keys (deprecated)
