Class EdECPrivateKeySpec

java.lang.Object

java.security.spec.EdECPrivateKeySpec

All Implemented Interfaces:

KeySpec

public final class EdECPrivateKeySpec
extends Object
implements KeySpec

A class representing elliptic curve private keys as defined in RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA), including the curve and other algorithm parameters. The private key is a bit string represented using a byte array. This class only supports bit string lengths that are a multiple of 8.

Since:

15

Constructor Details

EdECPrivateKeySpec

public EdECPrivateKeySpec(NamedParameterSpec params,
 byte[] bytes)

Construct a private key spec using the supplied parameters and bit string.

Parameters:

params - the algorithm parameters.

bytes - the key as a byte array. This array is copied to protect against subsequent modification.

Throws:

NullPointerException - if params or bytes is null.

Method Details

getParams

public NamedParameterSpec getParams()

Get the algorithm parameters that define the curve and other settings.

Returns:

the algorithm parameters.

getBytes

public byte[] getBytes()

Get the byte array representing the private key. A new copy of the array is returned each time this method is called.

Returns:

the private key as a byte array.
