Method Details
- initialize
  
  public void initialize(int keysize, SecureRandom random)
  
  Specified by:
  
  initialize in class KeyPairGeneratorSpi
- initialize
  
  public void initialize(AlgorithmParameterSpec params, SecureRandom random) throws InvalidAlgorithmParameterException
  
  Overrides:
  
  initialize in class KeyPairGeneratorSpi
  
  Throws:
  
  InvalidAlgorithmParameterException
- generateKeyPair
  
  public KeyPair generateKeyPair()
  
  Specified by:
  
  generateKeyPair in class KeyPairGeneratorSpi
- createNamedCurveSpec
  
  protected EdDSANamedCurveSpec createNamedCurveSpec(String curveName) throws InvalidAlgorithmParameterException
  
  Create an EdDSANamedCurveSpec from the provided curve name. The current implementation fetches the pre-created curve spec from a table.
  
  Parameters:
  
  curveName - the EdDSA named curve.
  
  Returns:
  
  the specification for the named curve.
  
  Throws:
  
  InvalidAlgorithmParameterException - if the named curve is unknown.
