Public Methods
public
String
getAlgorithmName
()
Return the name of the algorithm the cipher implements.
Returns
- the name of the algorithm the cipher implements.
public
int
getBlockSize
()
Return the block size for this cipher (in bytes).
Returns
- the block size for this cipher in bytes.
public
void
init
(boolean encrypting, CipherParameters params)
initialise a DESede cipher.
Parameters
encrypting
| whether or not we are for encryption. |
params
| the parameters required to set up the cipher. |
public
int
processBlock
(byte[] in, int inOff, byte[] out, int outOff)
Process one block of input from the array in and write it to
the out array.
Parameters
in
| the array containing the input data. |
inOff
| offset into the in array the data starts at. |
out
| the array the output data will be copied into. |
outOff
| the offset into the out array the output will start at. |
Returns
- the number of bytes processed and produced.
public
void
reset
()
Reset the cipher. After resetting the cipher is in the same state
as it was after the last init (if there was one).
