public interface EdECPrivateKey
implements EdECKey, PrivateKey

java.security.interfaces.EdECPrivateKey

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.

Summary

Inherited constants

From interface java.security.PrivateKey

long

serialVersionUID

This constant was deprecated in API level 34. A serialVersionUID field in an interface is ineffectual. Do not use; no replacement.

From interface java.security.Key

long

serialVersionUID

This constant was deprecated in API level 34. A serialVersionUID field in an interface is ineffectual. Do not use; no replacement.

Public methods
`abstract Optional<byte[]>`	`getBytes()` Get a copy of the byte array representing the private key.

Inherited methods

        NamedParameterSpec


      getParams()

Returns the algorithm parameters associated with the key.

From interface javax.security.auth.Destroyable

`default void`	`destroy()` Destroy this `Object`.
`default boolean`	`isDestroyed()` Determine if this `Object` has been destroyed.

From interface java.security.Key

`abstract String`	`getAlgorithm()` Returns the standard algorithm name for this key.
`abstract byte[]`	`getEncoded()` Returns the key in its primary encoding format, or null if this key does not support encoding.
`abstract String`	`getFormat()` Returns the name of the primary encoding format of this key, or null if this key does not support encoding.

Public methods

getBytes

public abstract Optional<byte[]> getBytes ()

Get a copy of the byte array representing the private key. This method may return an empty Optional if the implementation is not willing to produce the private key value.

Returns
`Optional<byte[]>`	an `Optional` containing the private key byte array. If the key is not available, then an empty `Optional`.
