EdECPrivateKeySpec

public final class EdECPrivateKeySpec
extends Object implements KeySpec

java.lang.Object
   ↳ java.security.spec.EdECPrivateKeySpec


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.

Summary

Public constructors

EdECPrivateKeySpec(NamedParameterSpec params, byte[] bytes)

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

Public methods

byte[] getBytes()

Get the byte array representing the private key.

NamedParameterSpec getParams()

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

Inherited methods

Public constructors

EdECPrivateKeySpec

Added in API level 33
public EdECPrivateKeySpec (NamedParameterSpec params, 
                byte[] bytes)

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

Parameters
params NamedParameterSpec: the algorithm parameters.

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

Throws
NullPointerException if params or bytes is null.

Public methods

getBytes

Added in API level 33
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
byte[] the private key as a byte array.

getParams

Added in API level 33
public NamedParameterSpec getParams ()

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

Returns
NamedParameterSpec the algorithm parameters.
