---|---|---|
int |
doFinal(byte[] out,
int outOff) |
Compute the final statge of the MAC writing the output to the out
parameter.
|
java.lang.String |
getAlgorithmName() |
Return the name of the algorithm the MAC implements.
|
int |
getMacSize() |
Return the block size for this cipher (in bytes).
|
void |
init(byte[] key) |
Initialise the MAC.
|
void |
reset() |
Reset the MAC.
|
void |
update(byte in) |
add a single byte to the mac for processing.
|
void |
update(byte[] in,
int inOff,
int len) |
void init(byte[] key) throws java.lang.IllegalArgumentException
key
- the key required by the MAC.java.lang.IllegalArgumentException
- if the params argument is
inappropriate.java.lang.String getAlgorithmName()
int getMacSize()
void update(byte in) throws java.lang.IllegalStateException
in
- the byte to be processed.java.lang.IllegalStateException
- if the MAC is not initialised.void update(byte[] in, int inOff, int len) throws java.lang.IllegalStateException
in
- the array containing the input.inOff
- the index in the array the data begins at.len
- the length of the input starting at inOff.java.lang.IllegalStateException
- if the MAC is not initialised.int doFinal(byte[] out, int outOff) throws java.lang.IllegalStateException
doFinal leaves the MAC in the same state it was after the last init.
out
- the array the MAC is to be output to.outOff
- the offset into the out buffer the output is to start at.java.lang.IllegalStateException
- if the MAC is not initialised.void reset()
