All Known Implementing Classes:

EcJWK, OkpJWK
```
public interface EllipticCurveJwk
```
Encapsulates common functionality for JWKs that represent elliptic curve keys: EcJWK and OkpJWK.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`SupportedEllipticCurve`	`getEllipticCurve()`	The elliptic curve this JWK is on.
`boolean`	`isPublicKeyValid()`	Determines whether the public key is a valid point on the underlying elliptic curve.
`ECPublicKey`	`toECPublicKey()`	Converts the public claims in the JWK into a public key object.
`KeyPair`	`toKeyPair()`	Converts the JWK to a key pair.
`PublicKey`	`toPublicKey()`	Converts the public claims in the JWK into a public key.

- Method Detail
  - isPublicKeyValid
```
boolean isPublicKeyValid()
```
    Determines whether the public key is a valid point on the underlying elliptic curve. This eliminates points of small-order and potentially other anomalous points. The caller should still check whether the point is on the curve it expected.
    
    Returns:
    
    true if the public key is a valid point on the curve.
  - toECPublicKey
```
ECPublicKey toECPublicKey()
```
    Converts the public claims in the JWK into a public key object. This method is only compatible with EcJWKs and will throw an exception if called on an OkpJWK.
    
    Returns:
    
    the public key.
  - toPublicKey
```
PublicKey toPublicKey()
```
    Converts the public claims in the JWK into a public key. Note that the public key returned may not be an ECPublicKey. For instance, on Java 11 an OkpJWK may return a XECPrivateKey.
    
    Returns:
    
    the public key.
  - toKeyPair
```
KeyPair toKeyPair()
```
    Converts the JWK to a key pair.
    
    Returns:
    
    the key pair.
  - getEllipticCurve
```
SupportedEllipticCurve getEllipticCurve()
```
    The elliptic curve this JWK is on.
    
    Returns:
    
    the elliptic curve.
