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

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

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.
