/** This test is intended to test the ESAPI command Esys_HMAC with password

|
|
* We create a symmetric HMAC key signing key which will be used
|

* for signing. This key will be used to create the HMAC for a test

|
|
* Tested ESAPI commands:
|
|
* - Esys_CreatePrimary() (M)
|
|
* - Esys_FlushContext() (M)
|
|
* - Esys_HMAC() (O)
|

* @param[in,out] esys_context The ESYS_CONTEXT.
