# 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()
    Returns the parameters associated with this key. The parameters are optional and may be either explicitly specified or implicitly created during key pair generation.
    Specified by:
      `getParams` in interface `AsymmetricKey`
    Specified by:
      `getParams` in interface `EdECKey`
    Implementation Requirements:
      The default implementation returns `null`.
    Returns:
      the associated parameters, may be `null`
