ECPublicKey

AI-generated Key Takeaways

• ECPublicKey interface provides access to an elliptic curve public key, extending PublicKey and ECKey.

• It includes a method getW() to retrieve the public point W of the key.

• You can obtain the elliptic curve domain parameters using the inherited getParams() method.

• Standard key functionalities like getting the algorithm, encoded key, and format are inherited from the Key interface.
