    • init

      public void init(boolean forEncryption, CipherParameters params) throws IllegalArgumentException
      Description copied from interface: BlockCipher
      Initialise the cipher.
      Specified by:
      init in interface BlockCipher
      Parameters:
      forEncryption - if true the cipher is initialised for encryption, if false for decryption.
      params - the key and other data required by the cipher.
      Throws:
      IllegalArgumentException - if the params argument is inappropriate.

    • getAlgorithmName

      public 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[] in, int inOff, byte[] out, int outOff) throws DataLengthException, IllegalStateException
      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.
      Throws:
      DataLengthException - if there isn't enough data in input , or space in out.
      IllegalStateException - if the cipher isn't initialised.

    • 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
