ECPublicKeySpec

public ECPublicKeySpec(ECPoint w,
                       ECParameterSpec params)

Creates a new ECPublicKeySpec with the specified parameter values.

参数:

w - the public point.

params - the associated elliptic curve domain parameters.

抛出:

NullPointerException - if w or params is null.

IllegalArgumentException - if w is point at infinity, i.e. ECPoint.POINT_INFINITY
