Method Detail

inetAddressToInt

public static int inetAddressToInt(URI serverUrl,
                                   InetAddress requesterIpAddress,
                                   SqrlConfig config)
                            throws SqrlException

Throws:

SqrlException

validateInetAddress

public static boolean validateInetAddress(InetAddress requesterIpAddress,
                                          int inetInt,
                                          SqrlConfig config)
                                   throws SqrlException

Throws:

SqrlException

validateNut

public static void validateNut(String correlator,
                               SqrlNutToken nutToken,
                               SqrlConfig config,
                               SqrlPersistence sqrlPersistence,
                               SqrlTif.TifBuilder tifBuilder)
                        throws SqrlException

Validates the SqrlNutToken from the SqrlClientRequest by:

1. check the timestamp embedded in the Nut has expired 2. call SqrlPersistence to see if the Nut has been replayed

Parameters:

correlator -

nutToken - the Nut to be validated

tifBuilder -

Throws:

SqrlException - if any validation fails or if persistence fails

computeNutExpiresAt

public static long computeNutExpiresAt(SqrlNutToken nutToken,
                                       SqrlConfig config)

Computes when a given SQRL "nut" nonce token will expire

Parameters:

nutToken - the token for which expiration time will be computed

config - the SQRL config

Returns:

the time, in millis, when the token will expire
