• java.lang.Object

Fields Summary
private ECPoint	w
private ECParameterSpec	params

Constructors Summary

public ECPublicKeySpec(ECPoint w, ECParameterSpec params) Creates a new ECPublicKeySpec with the specified parameter values. param w the public point. param params the associated elliptic curve domain parameters. exception NullPointerException if w or params is null. exception IllegalArgumentException if w is point at infinity, i.e. ECPoint.POINT_INFINITY if (w == null) { throw new NullPointerException("w is null"); } if (params == null) { throw new NullPointerException("params is null"); } if (w == ECPoint.POINT_INFINITY) { throw new IllegalArgumentException("w is ECPoint.POINT_INFINITY"); } this.w = w; this.params = params;

Methods Summary
public java.security.spec.ECParameterSpec	getParams() Returns the associated elliptic curve domain parameters. return the EC domain parameters. return params;
public java.security.spec.ECPoint	getW() Returns the public point W. return the public point W. return w;
