Constructors

ECPublicKeySpec

public ECPublicKeySpec(ECPoint w,
                       ECParameterSpec params)

Creates a new ECPublicKeySpec with the specified parameter values.

Parameters:

w - the public point.

params - the associated elliptic curve domain parameters.

Throws:

NullPointerException - if w or params is null.

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

Methods

getW

public ECPoint getW()

Returns the public point W.

Returns:

the public point W.

getParams

public ECParameterSpec getParams()

Returns the associated elliptic curve domain parameters.

Returns:

the EC domain parameters.
