Equal symmetric encryption and decryption algorithm AES
==============================================================================================================

Overview
--------

**aes_example**  the example project shows the implementation of AES mode of equal symmetric encryption and decryption algorithm.
- The equal symmetry encryption and decryption algorithm of this project adopts aes128 NIST mode to complete the module encryption and decryption test.

Board Setting
-------------

- No special settings

Running the example
-------------------

When the project runs correctly, and the serial port terminal will output the following information:

.. code-block:: console

   tc_start() - Performing AES128 tests:
   AES128 test_1 (NIST key schedule test):
   ===================================================================
   PASS - test_1.
   AES128 test_2 (NIST encryption test):
   ===================================================================
   PASS - test_2.
   AES128 test_3 (NIST fixed-key and variable-text):
   ===================================================================
   PASS - test_3.
   AES128 test #4 (NIST variable-key and fixed-text):
   ===================================================================
   PASS - test_4.
   All AES128 tests succeeded!
   ===================================================================
   PASS - main.
