public class EdDSAPrivateKey extends Object implements EdDSAKey, PrivateKey
Warning: Private key encoding is based on the current curdle WG draft, and is subject to change. See getEncoded().
For compatibility with older releases, decoding supports both the old and new draft specifications. See decode().

This implements the following specs:
This encodes the seed. It will return null if constructed from a spec which was directly constructed from H, in which case seed is null.
For keys in older formats, decoding and then re-encoding is sufficient to migrate them to the canonical encoding.
Relevant spec quotes:OneAsymmetricKey ::= SEQUENCE { version Version, privateKeyAlgorithm PrivateKeyAlgorithmIdentifier, privateKey PrivateKey, attributes [0] Attributes OPTIONAL, ..., [[2: publicKey [1] PublicKey OPTIONAL ]], ... } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING PublicKey ::= OCTET STRING Attributes ::= SET OF Attribute
... when encoding a OneAsymmetricKey object, the private key is wrapped in a CurvePrivateKey object and wrapped by the OCTET STRING of the 'privateKey' field. CurvePrivateKey ::= OCTET STRING
AlgorithmIdentifier ::= SEQUENCE { algorithm OBJECT IDENTIFIER, parameters ANY DEFINED BY algorithm OPTIONAL } For all of the OIDs, the parameters MUST be absent.
id-Ed25519 OBJECT IDENTIFIER ::= { 1 3 101 112 }
