extends Object implements KeySpec



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

Summary

Public constructors

ECPrivateKeySpec(BigInteger s, ECParameterSpec params)

Creates a new ECPrivateKeySpec with the specified parameter values.

Public methods

ECParameterSpec getParams()

Returns the associated elliptic curve domain parameters.

BigInteger getS()

Returns the private value S.

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.
