Method Summary

Modifier and Type	Method and Description
public int	Returns: the amount of data written to output. doFinal(byte[] array holding input data to the cipher. input, int offset into input array data starts at. inputOffset, int length of the input data in the array. inputLength, byte[] array to hold the cipher output. output, int offset into output array to start saving output. outputOffset) Perform the cipher encryption/decryption returning the output in output.
public int	Returns: the cipher's blocksize. getBlockSize() Return the blocksize (in bytes) of the underlying block cipher.
public void	init(byte[] array holding the initialization vector (IV). iv, int offset into the array the IV starts at. ivOff, int length of the IV in the array. ivLen) Initialise the parameters for operator.
public void	setKey(byte[] array holding the block cipher key. key, int offset into the array the key starts at. keyOff, int length of the key in the array. keyLen) Set the key to be used by the block cipher implementation supporting this service.

doFinal	back to summary
public int doFinal(byte[] input, int inputOffset, int inputLength, byte[] output, int outputOffset) throws IOException Perform the cipher encryption/decryption returning the output in output. Note we have to use doFinal() here as it is the only way to guarantee output from the underlying cipher. Parameters input:byte[] array holding input data to the cipher. inputOffset:int offset into input array data starts at. inputLength:int length of the input data in the array. output:byte[] array to hold the cipher output. outputOffset:int offset into output array to start saving output. Returns:int the amount of data written to output. Exceptions IOException: in case of failure.

doFinal

public int doFinal(byte[] input, int inputOffset, int inputLength, byte[] output, int outputOffset) throws IOException

Perform the cipher encryption/decryption returning the output in output.

Note

we have to use doFinal() here as it is the only way to guarantee output from the underlying cipher.

Parameters

Returns:int

the amount of data written to output.

Exceptions

getBlockSize	back to summary
public int getBlockSize() Return the blocksize (in bytes) of the underlying block cipher. Returns:int the cipher's blocksize.

getBlockSize

public int getBlockSize()

Return the blocksize (in bytes) of the underlying block cipher.

init	back to summary
public void init(byte[] iv, int ivOff, int ivLen) throws IOException Initialise the parameters for operator. Parameters iv:byte[] array holding the initialization vector (IV). ivOff:int offset into the array the IV starts at. ivLen:int length of the IV in the array. Exceptions IOException: if the parameters are inappropriate.

init

public void init(byte[] iv, int ivOff, int ivLen) throws IOException

Initialise the parameters for operator.

Parameters

Parameters key:byte[] array holding the block cipher key. keyOff:int offset into the array the key starts at. keyLen:int length of the key in the array.

setKey

public void setKey(byte[] key, int keyOff, int keyLen) throws IOException
