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.
