net.i2p.crypto.eddsa.EdDSAPublicKey
- All Implemented Interfaces:
Serializable
,Key
,PublicKey
,EdDSAKey
An EdDSA public key.
For compatibility with older releases, decoding supports both RFC 8410 and an older draft specification.

getEncoded
public byte[] getEncoded()Returns the public 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
For keys in older formats, decoding and then re-encoding is sufficient to migrate them to the canonical encoding.
Relevant spec quotes:
In the X.509 certificate, the subjectPublicKeyInfo field has the SubjectPublicKeyInfo type, which has the following ASN.1 syntax: SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT 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:

in interfaceKey
- Returns:
- 44 bytes for Ed25519, null for other curves
