Method Detail

init

public void init(boolean pEncrypt,
                 CipherParameters pParams)

Description copied from interface: BlockCipher

Initialise the cipher.

Specified by:

init in interface BlockCipher

Parameters:

pEncrypt - if true the cipher is initialised for encryption, if false for decryption.

pParams - the key and other data required by the cipher.

reset

public void reset()

Description copied from interface: BlockCipher

Reset the cipher. After resetting the cipher is in the same state as it was after the last init (if there was one).

Specified by:

reset in interface BlockCipher

getAlgorithmName

public java.lang.String getAlgorithmName()

Description copied from interface: BlockCipher

Return the name of the algorithm the cipher implements.

Specified by:

getAlgorithmName in interface BlockCipher

Returns:

the name of the algorithm the cipher implements.

getBlockSize

public int getBlockSize()

Description copied from interface: BlockCipher

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

Specified by:

getBlockSize in interface BlockCipher

Returns:

the block size for this cipher in bytes.

processBlock

public int processBlock(byte[] pInput,
                        int pInOff,
                        byte[] pOutput,
                        int pOutOff)

Description copied from interface: BlockCipher

Process one block of input from the array in and write it to the out array.

Specified by:

processBlock in interface BlockCipher

Parameters:

pInput - the array containing the input data.

pInOff - offset into the in array the data starts at.

pOutput - the array the output data will be copied into.

pOutOff - the offset into the out array the output will start at.

Returns:

the number of bytes processed and produced.
