Interface EdECPublicKey

All Superinterfaces:
AsymmetricKey, DEREncodablePREVIEW, EdECKey, Key, PublicKey, Serializable
public interface EdECPublicKey extends EdECKey, PublicKey
An interface for an elliptic curve public key as defined by RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA). These keys are distinct from the keys represented by ECPublicKey, and they are intended for use with algorithms based on RFC 8032 such as the EdDSA Signature algorithm.

An Edwards-Curve public key is a point on the curve, which is represented using an EdECPoint.

  • Method Details

    • getPoint

      EdECPoint getPoint()
      Get the point representing the public key.
      Returns:
      the EdECPoint representing the public key.

    • getParams

      default NamedParameterSpec getParams()
