Class ECPublicKeySpec

  • All Implemented Interfaces:
    KeySpec 

    public class ECPublicKeySpec
extends Object
implements KeySpec
    This immutable class specifies an elliptic curve public key with its associated parameters.

    • Constructor Detail

      • 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
