ECPrivateKeySpec

AI-generated Key Takeaways

ECPrivateKeySpec is an immutable class that defines an elliptic curve private key and its parameters.
It includes a constructor to create a new ECPrivateKeySpec with a private value (S) and elliptic curve domain parameters (ECParameterSpec).
This class provides methods to retrieve the associated elliptic curve domain parameters (getParams()) and the private value (getS()).
ECPrivateKeySpec inherits methods from java.lang.Object, such as clone(), equals(), hashCode(), and toString().

public class ECPrivateKeySpec extends Object
implements KeySpec

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

ECPrivateKeySpec(BigInteger s, ECParameterSpec params)

Creates a new ECPrivateKeySpec with the specified parameter values.

ECParameterSpec	getParams() Returns the associated elliptic curve domain parameters.
BigInteger	getS() Returns the private value S.

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 ECPrivateKeySpec with the specified parameter values.

s	the private value.
params	the associated elliptic curve domain parameters.

NullPointerException	if `s` or `params` is null.

Returns the associated elliptic curve domain parameters.

Returns the private value S.
