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

Overview
--------

**aes_ctr_mode_example**  the example project shows the implementation of aes-ctr mode of equal symmetric encryption and decryption algorithm.
- The equal symmetry encryption and decryption algorithm of this project adopts aes128 encryption algorithm CTR counting 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-CTR mode tests:
   Performing CTR tests:
   CTR test #1 (encryption SP 800-38a tests):
   ===================================================================
   PASS - test_1_and_2.
   CTR test #2 (decryption SP 800-38a tests):
   ===================================================================
   PASS - test_1_and_2.
   All CTR tests succeeded!
   ===================================================================
   PASS - main.
