se.swedenconnect.sigval.commons.algorithms.NamedCurveRegistry

public class NamedCurveRegistry
extends Object

Registry over supported named EC curves. Any EC curve can be specified using the defined curve parameters of EC cryptography. Some curves with specific parameters have been assigned OID identifiers. These are called "named curves"
