Method Detail

generateHMACSHA1

public static Map<String,String> generateHMACSHA1(DeviceHandler deviceHandler,
                                  byte[] data,
                                  int keyHandle,
                                  byte flags,
                                  boolean last,
                                  boolean toBuffer)
                                           throws YubiHSMCommandFailedException,
                                                  YubiHSMErrorException,
                                                  YubiHSMInputException

Generate HMAC SHA1 using a key handle in the YubiHSM.

Parameters:

deviceHandler - the device handler

data - the data used to generate the SHA1

keyHandle - the key handle to use in the YubiHSM

flags - the commands flags, send (byte) 0 to use defaults

last - set to false to not get a hash generated for the initial request

toBuffer - set to true to get the SHA1 stored into the internal buffer, for use in some other cryptographic operations.

Returns:

a map containing status and SHA1 hash

Throws:

YubiHSMCommandFailedException - if the YubiHSM fail to execute the command

YubiHSMErrorException - if validation fail for some values returned by the YubiHSM

YubiHSMInputException - if an argument does not validate

execHMACSHA1_Raw

public static byte[] execHMACSHA1_Raw(DeviceHandler deviceHandler,
                      byte[] data,
                      int keyHandle,
                      byte flags)
                               throws YubiHSMCommandFailedException,
                                      YubiHSMErrorException,
                                      YubiHSMInputException

Generate HMAC SHA1 using a key handle in the YubiHSM.

Parameters:

deviceHandler - the device handler

data - the data used to generate the SHA1

keyHandle - the key handle to use in the YubiHSM

flags - the commands flags, send (byte) 0 to use defaults

Returns:

an array of bytes

Throws:

YubiHSMCommandFailedException - if the YubiHSM fail to execute the command

YubiHSMErrorException - if validation fail for some values returned by the YubiHSM

YubiHSMInputException - if an argument does not validate

next

public static Map<String,String> next(DeviceHandler deviceHandler,
                      byte[] data,
                      int keyHandle,
                      boolean last,
                      boolean toBuffer)
                               throws YubiHSMCommandFailedException,
                                      YubiHSMErrorException,
                                      YubiHSMInputException

Add more input to the HMAC SHA1.

Parameters:

deviceHandler - the device handler

data - the data to add before generating SHA1

keyHandle - the key handle to use in the YubiHSM

last - set to false to not get a hash generated after this call

toBuffer - set to true to get the SHA1 stored into the internal buffer, for use in some other cryptographic operations.

Returns:

a map containing status and SHA1 hash

Throws:

YubiHSMCommandFailedException - if the YubiHSM fail to execute the command

YubiHSMErrorException - if validation fail for some values returned by the YubiHSM

YubiHSMInputException - if an argument does not validate
