| Symmetric AES Example |
| ======================================================================= |
| |
| This project demonstrates symmetric cryptography - AES encryption and decryption operations. |
| |
| Refer - :file:`simw-top/sss/ex/symmetric/ex_sss_symmetric.c` |
| |
| Prerequisites |
| ======================================================================= |
| |
| - Build Plug & Trust middleware stack. (Refer :ref:`building`) |
| |
| |
| About the Example |
| ======================================================================= |
| This example does a symmetric cryptography AES encryption and decryption operation. |
| |
| It uses the following APIs and data types: |
| - :cpp:func:`sss_symmetric_context_init()` |
| - :cpp:enumerator:`kAlgorithm_SSS_AES_CBC` from :cpp:type:`sss_algorithm_t` |
| - :cpp:enumerator:`kSSS_CipherType_AES` from :cpp:type:`sss_cipher_type_t` |
| - :cpp:enumerator:`kMode_SSS_Encrypt` from :cpp:type:`sss_mode_t` |
| - :cpp:func:`sss_cipher_one_go()` |
| - :cpp:enumerator:`kMode_SSS_Decrypt` from :cpp:type:`sss_mode_t` |
| |
| |
| |
| Console output |
| ======================================================================= |
| |
| |
| If everything is successful, the output will be similar to: |
| |
| .. literalinclude:: out_ex_symmetric.rst.txt |
| :start-after: sss :WARN :!!!Not recommended for production use.!!! |
