| RSA Example |
| ======================================================================= |
| |
| This project demonstrates RSA sign and verify operations using SSS APIs. |
| |
| Refer - :file:`simw-top/sss/ex/rsa/ex_sss_rsa.c` |
| |
| Prerequisites |
| ======================================================================= |
| |
| - Build Plug & Trust middleware stack. (Refer :ref:`building`) |
| |
| |
| About the Example |
| ======================================================================= |
| This example does a RSA signing and verify operation. |
| |
| It uses the following APIs and data types: |
| - :cpp:func:`sss_asymmetric_context_init()` |
| - :cpp:enumerator:`kAlgorithm_SSS_RSASSA_PKCS1_PSS_MGF1_SHA256` from :cpp:type:`sss_algorithm_t` |
| - :cpp:enumerator:`kMode_SSS_Sign` from :cpp:type:`sss_mode_t` |
| - :cpp:enumerator:`kSSS_CipherType_RSA` from :cpp:enumerator: `sss_cipher_type_t` |
| - :cpp:func:`sss_asymmetric_sign_digest()` |
| - :cpp:enumerator:`kMode_SSS_Verify` from :cpp:type:`sss_mode_t` |
| - :cpp:func:`sss_asymmetric_verify_digest()` |
| |
| .. note:: |
| This example tries to delete key first. Deletion would be successful, if the key already exists. |
| Otherwise it would return an error message which is perfectly alright and the example could be successfully executed. |
| |
| |
| |
| Console output |
| ======================================================================= |
| |
| |
| If everything is successful, the output will be similar to: |
