Constructor Detail

NoekeonEngine

public NoekeonEngine()
Create an instance of the Noekeon encryption algorithm and set some defaults

Method Detail

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.

init

public void init(boolean forEncryption,
                 CipherParameters params)
initialise

Specified by:
init in interface BlockCipher
Parameters:
forEncryption - whether or not we are for encryption.
params - the parameters required to set up the cipher.
Throws:
java.lang.IllegalArgumentException - if the params argument is inappropriate.

processBlock

public int processBlock(byte[] in,
                        int inOff,
                        byte[] out,
                        int outOff)
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:
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.

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
