EdECPrivateKeySpec

class EdECPrivateKeySpec : KeySpec
kotlin.Any
   ↳ 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

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

Public methods
ByteArray

Get the byte array representing the private key.

NamedParameterSpec

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

EdECPrivateKeySpec(
    params: NamedParameterSpec,
    bytes: ByteArray)

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

Parameters
params NamedParameterSpec: the algorithm parameters.
bytes ByteArray: the key as a byte array. This array is copied to protect against subsequent modification.
Exceptions
java.lang.NullPointerException if params or bytes is null.

Public methods

getBytes

Added in API level 33
fun getBytes(): ByteArray

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

Return
ByteArray the private key as a byte array.

getParams

Added in API level 33
fun getParams(): NamedParameterSpec

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

Return
NamedParameterSpec the algorithm parameters.
