=======================================================================
 SE05X WiFi KDF Example
=======================================================================

This project is to demonstrate Password based KDF (PBKDF) operation using
SE05X. This operation is used in deriving Pre-Shared key (PSK) for WiFi ssid
using stored passwords.


Building the Demo
=======================================================================

- Build Plug & Trust middleware stack. (Refer :ref:`building`)
- Project: ``ex_se05x_WiFiKDF_inject``
- Project: ``ex_se05x_WiFiKDF_derive``


Running the Example
=======================================================================

If you have built a binary, first flash the ``ex_se05x_WiFiKDF_inject``
binary on to the board and reset the board. Then flash ``ex_se05x_WiFiKDF_derive``
binary and reset the board.

If you have built an *exe* to be run from PC using VCOM, run as::

    ex_se05x_WiFiKDF_inject.exe <PORT NAME>
    ex_se05x_WiFiKDF_derive.exe -s <ssid_name> <PORT NAME>

Where **<PORT NAME>** is the VCOM COM port and **<ssid_name>** is the
name of SSID for which you want to derive the PSK.


Console output
=======================================================================

During injection, if everything is successful, the output will be similar to:

.. literalinclude:: out_ex_se05x_WiFiKDF_inject.rst.txt
   :start-after: sss   :WARN :!!!Not recommended for production use.!!!

While deriving the key, if everything is successful, the output will be similar to:

.. literalinclude:: out_ex_se05x_WiFiKDF_derive.rst.txt
   :start-after: sss   :WARN :!!!Not recommended for production use.!!!
