| /** This test is intended to test parameter encryption/decryption, session management, |
| * hmac computation, and session key generation. |
| * |
| * We start by creating a primary key (Esys_CreatePrimary). |
| * The primary key will be used as tpmKey for Esys_StartAuthSession. Parameter |
| * encryption and decryption will be activated for the session. |
| * The session will be used to Create a second key by Eys_Create (with password) |
| * This key will be Loaded to and a third key will be created with the second |
| * key as parent key (Esys_Create). |
| * The type of encryptin can be selected by the compiler variables (-D option): |
| * TEST_XOR_OBFUSCATION or TEST_AES_ENCRYPTION. |
| * Secret exchange with a ECC key can be activated with the compiler variable |
| * -D TEST_ECC. |
| * |
| * Tested ESYS commands: |
| * - Esys_ContextLoad() (M) |
| * - Esys_ContextSave() (M) |
| * - Esys_Create() (M) |
| * - Esys_CreatePrimary() (M) |
| * - Esys_FlushContext() (M) |
| * - Esys_Load() (M) |
| * - Esys_StartAuthSession() (M) |
| * |
| * Used compiler defines: TEST_ECC, TEST_AES_ENCRYPTION, TEST_BOUND_SESSION |
| * TEST_XOR_OBFUSCATION |
| * |
| * @param[in,out] esys_context The ESYS_CONTEXT. |
| * @retval EXIT_FAILURE |
