Public Constructors

public RC2Engine ()

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 RC2 cipher.

Parameters
encrypting whether or not we are for encryption.
params the parameters required to set up the cipher.
Throws
IllegalArgumentException if the params argument is inappropriate.

public final 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).
