    transform(byte[] data)
    Transform the byte array according to the cipher mode.
    void
    transform(byte[] src, int start, byte[] dest, int offset, int len)
    Transform the byte array according to the cipher mode; it is legal for the source and destination arrays to reference the same physical array so care should be taken in the transformation process to safeguard this rule.

    • init

      void init(int mode, byte[] iv, byte[] keydata) throws IOException
      Initialize the cipher with up to 40 bytes of iv and key data. Each implementation should take as much data from the initialization as it needs ignoring any data that it does not require.
      Parameters:
      mode - the mode to operate
      iv - the initiaization vector
      keydata - the key data
      Throws:
      IOException

    • transform

      void transform(byte[] data) throws IOException
      Transform the byte array according to the cipher mode.
      Parameters:
      data -
      Throws:
      IOException

    • transform

      void transform(byte[] src, int start, byte[] dest, int offset, int len) throws IOException
      Transform the byte array according to the cipher mode; it is legal for the source and destination arrays to reference the same physical array so care should be taken in the transformation process to safeguard this rule.
      Parameters:
      src -
      start -
      dest -
      offset -
      len -
      Throws:
      IOException
