Doc from org.bouncycastle.openpgp.operator.PGPKeyPairGenerator.generateEd25519KeyPair.

Generate an elliptic curve signing key over the twisted Edwards curve25519. The key will use PublicKeyAlgorithmTags#Ed25519 which was introduced with RFC9580. For legacy Ed25519 keys use generateLegacyEd25519KeyPair().

Returns:PGPKeyPair

Doc from org.bouncycastle.openpgp.operator.PGPKeyPairGenerator.generateLegacyEd25519KeyPair.

Generate a legacy elliptic curve signing key pair over the twisted Edwards curve25519. Legacy keys have good application support, but MUST NOT be used as OpenPGP v6 keys. The key will use PublicKeyAlgorithmTags#EDDSA_LEGACY as algorithm ID. For OpenPGP v6 (RFC9580) use generateEd25519KeyPair() instead.
