Method Summary

Modifier and Type	Method and Description
int	getMultiBlockSize() Return the multi-block size for this cipher (in bytes).
int	processBlocks(byte[] in, int inOff, int blockCount, byte[] out, int outOff) Process blockCount blocks from input in offset inOff and place the output in out from offset outOff.

Method Detail

getMultiBlockSize

int getMultiBlockSize()

Return the multi-block size for this cipher (in bytes).

Returns:

the multi-block size for this cipher in bytes.

processBlocks

int processBlocks(byte[] in,
                  int inOff,
                  int blockCount,
                  byte[] out,
                  int outOff)
           throws DataLengthException,
                  java.lang.IllegalStateException

Process blockCount blocks from input in offset inOff and place the output in out from offset outOff.

Parameters:

in - input data array.

inOff - start of input data in in.

blockCount - number of blocks to be processed.

out - output data array.

outOff - start position for output data.

Returns:

number of bytes written to out.

Throws:

DataLengthException
