The Bouncy Castle Java API for handling the OpenPGP protocol. This jar contains the OpenPGP API for JDK 1.8 and up. The APIs can be used in conjunction with a JCE/JCA provider such as the one provided with the Bouncy Castle Cryptography APIs.

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)
