# Equal symmetric encryption and decryption algorithm AES-CTR ## Overview **aes_ctr_prng_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 AES encryption algorithm ctr-prng 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: ```console tc_start() - Performing CTR-PRNG tests: All CTR PRNG tests succeeded! =================================================================== PASS - main. =================================================================== PROJECT EXECUTION SUCCESSFUL ```
