/** This test is intended to test Esys_ECDH_ZGen.

|
|
* The test is based on an ECC key created with Esys_CreatePrimary
|
|
* and data produced by the command Esys_EC_Ephemeral.
|
|
*
|
|
* Tested ESAPI commands:
|
|
* - Esys_CreatePrimary() (M)
|
|
* - Esys_ECDH_ZGen() (M)
|
|
* - Esys_EC_Ephemeral() (F)
|
|
* - Esys_FlushContext() (M)
|
|
* - Esys_StartAuthSession() (M)
|
|
* - Esys_ZGen_2Phase() (O)
|
|
*
|
|
* @param[in,out] esys_context The ESYS_CONTEXT.
