getEncoded
public byte[] getEncoded()Returns the private key in its canonical encoding.This implements the following specs:
- General encoding: https://tools.ietf.org/html/rfc8410
- Key encoding: https://tools.ietf.org/html/rfc8032
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] IMPLICIT Attributes OPTIONAL, ..., [[2: publicKey [1] IMPLICIT PublicKey OPTIONAL ]], ... } Version ::= INTEGER PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier PrivateKey ::= OCTET STRING PublicKey ::= BIT 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 }
- Specified by:
