Class ECKeySizeParameterSpec

java.lang.Object

com.tencent.kona.sun.security.util.ECKeySizeParameterSpec

All Implemented Interfaces:

java.security.spec.AlgorithmParameterSpec

public class ECKeySizeParameterSpec
extends java.lang.Object
implements java.security.spec.AlgorithmParameterSpec

This immutable class is used when randomly generating a key pair and the consumer only specifies the length of the key and therefore a curve for that key size must be picked from a the list of supported curves using this spec.

ECKeySizeParameterSpec

public ECKeySizeParameterSpec(int keySize)

Creates a parameter specification for EC curve generation using a standard (or predefined) key size keySize in order to generate the corresponding (precomputed) elliptic curve.

Note, if the curve of the specified length is not supported, AlgorithmParameters.init will throw an exception.

Parameters:

keySize - the key size of the curve to lookup

Method Detail

getKeySize

public int getKeySize()

Returns the key size of this spec.

Returns:

the standard or predefined key size.
