ECPublicKeySpec

AI-generated Key Takeaways

ECPublicKeySpec is an immutable class that defines an elliptic curve public key along with its parameters.
It includes the public point W and the associated elliptic curve domain parameters.
You can retrieve the public point using getW() and the domain parameters using getParams().
A new ECPublicKeySpec is created using the public point and domain parameters, throwing exceptions if inputs are invalid.

public class ECPublicKeySpec extends Object
implements KeySpec

This immutable class specifies an elliptic curve public key with its associated parameters.

ECPublicKeySpec(ECPoint w, ECParameterSpec params)

Creates a new ECPublicKeySpec with the specified parameter values.

ECParameterSpec	getParams() Returns the associated elliptic curve domain parameters.
ECPoint	getW() Returns the public point W.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.

Creates a new ECPublicKeySpec with the specified parameter values.

w	the public point.
params	the associated elliptic curve domain parameters.

NullPointerException	if `w` or `params` is null.
IllegalArgumentException	if `w` is point at infinity, i.e. ECPoint.POINT_INFINITY

Returns the associated elliptic curve domain parameters.

Returns the public point W.
