/** This test is intended to test the function Esys_MakeCredential
 *  We start by creating a primary key (Esys_CreatePrimary).
 *
 * Based in the primary a second key will be created.
 * The public part of the key will be loaded by the function
 * Esys_LoadExternal. A credential will be encrypted with this
 * key with the command Esys_MakeCredential. The credential
 * will be activated with Esys_ActivateCredential.
 *
 * Tested ESAPI commands:
 *  - Esys_ActivateCredential() (M)
 *  - Esys_Create() (M)
 *  - Esys_CreatePrimary() (M)
 *  - Esys_FlushContext() (M)
 *  - Esys_Load() (M)
 *  - Esys_LoadExternal() (M)
 *  - Esys_MakeCredential() (M)
 *  - Esys_ReadPublic() (M)
 *  - Esys_StartAuthSession() (M)
 *
 * Used compiler defines: TEST_SESSION
 *
 * @param[in,out] esys_context The ESYS_CONTEXT.
