      public static NamedECDomainParameters lookupDomainParameters(ASN1ObjectIdentifier paramOid)
      Retrieve an EC based domain parameter by OID. A custom curve will be returned if one is available.
      Parameters:
      paramOid - object identifier for the domain parameters.
      Returns:
      the matching domain parameters if found, null otherwise.
