An interface for an elliptic curve private key as defined by
RFC 8032: Edwards-Curve
Digital Signature Algorithm (EdDSA). These keys are distinct from the
keys represented by
ECPrivateKey
, and they are intended for use
with algorithms based on RFC 8032 such as the EdDSA Signature
algorithm.
An Edwards-Curve private key is a bit string. This interface only supports bit string lengths that are a multiple of 8, and the key is represented using a byte array.

Method Details
-
getBytes
Optional<byte[]> getBytes()Get a copy of the byte array representing the private key. This method may return an emptyOptional
if the implementation is not willing to produce the private key value.- Returns:
- an
Optional
containing the private key byte array. If the key is not available, then an emptyOptional
.
