    Specified by:
    
    getEllipticCurve in interface EllipticCurveJwk
    
    Returns:
    
    the curve.
  - getX
```
public String getX()
```

    the public key x-coordinate.
  - getD
```
public String getD()
```
    Returns the private key d value.
    
    Returns:
    
    the private key d value.
  - parse
```
public static OkpJWK parse(JsonValue json)
```
    Parses a JWK from a JsonValue json object.
    
    Parameters:
    
    json - JsonValue json object
    
    Returns:
    
    a OctJWK object
  - toJsonValue
```
public JsonValue toJsonValue()
```
    Description copied from class: JWK
    
    Returns a json representation of the JWK.
    
    Overrides:
    
    toJsonValue in class JWK
    
    Returns:
    
    A JSON representation.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - isPrivate
```
public boolean isPrivate()
```
    Description copied from class: JWK
    
    Indicates if any private key attributes are present in the JWK.
    
    Overrides:
    
    isPrivate in class JWK
    
    Returns:
    
    true if this JWK contains any private key attributes.
  - getPublicJwkBuilder
```
protected Optional<JWK.Builder<?>> getPublicJwkBuilder()
```
    Description copied from class: JWK
    
    Return a builder with all the values set for representing the public components of the JWK. Common JWK attributes will be added in JWK.toPublicJwk().
    
    Specified by:
    
    getPublicJwkBuilder in class JWK
    
    Returns:
    
    The builder.
  - toPrivateKey
```
public PrivateKey toPrivateKey()
```
    Converts the JWK to a private key object.
    
    Returns:
    
    the equivalent private key object.
  - toXECPublicKey
```
public PublicKey toXECPublicKey()
```
    Converts the JWK to a Java 11 XECPublicKey instance. If using Java prior to Java 11 then this returns null.
    
    Returns:
    
    the XECPublicKey corresponding to this JWK.
  - toXECKeyPair
```
public KeyPair toXECKeyPair()
```
    Returns a KeyPair object containing the XECPrivateKey and XECPublicKey for this JWK. Only supported in Java 11+. On earlier Java versions it will return a pair of null keys.
    
    Returns:
    
    the XEC key pair.
  - toECPublicKey
```
public ECPublicKey toECPublicKey()
```
    Description copied from interface: EllipticCurveJwk
    
    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.
    
    Specified by:
    
    toECPublicKey in interface EllipticCurveJwk
    
    Returns:
    
    the public key.
  - toPublicKey
```
public PublicKey toPublicKey()
```
    Description copied from interface: EllipticCurveJwk
    
    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.
    
    Specified by:
    
    toPublicKey in interface EllipticCurveJwk
    
    Returns:
    
    the public key.
  - isPublicKeyValid
```
public boolean isPublicKeyValid()
```
    Determines whether the public key is valid. Currently for Curve25519, we blacklist all the points of small-order given by https://cr.yp.to/ecdh.html#validate.
    
    Specified by:
    
    isPublicKeyValid in interface EllipticCurveJwk
    
    Returns:
    
    true if the public key is a valid point on the curve.
  - toKeyPair
```
public KeyPair toKeyPair()
```
    Converts the JWK to a key-pair.
    
    Specified by:
    
    toKeyPair in interface EllipticCurveJwk
    
    Returns:
    
    the key-pair equivalent to this JWK.
  - generateKeyPair
```
public static OkpJWK generateKeyPair(SupportedEllipticCurve curve)

    Returns:
    
    the freshly generated JWK.
