My generic answer to these questions is to debug with a SW TPM.  The
trace will tell you exactly what parameter is wrong.

I am trying to create a pair of keys through openssl and wrap the key using SRK.

I wrapped the key using a parent key which in turn is wrapped by SRK. When I load the parent key first, it returns success. When I load the actual key(hKey), it returns unsupported key parameters.

initFlags for hKey

initFlags = TSS_KEY_TYPE_LEGACY | TSS_KEY_SIZE_2048  |
                   TSS_KEY_VOLATILE | TSS_KEY_AUTHORIZATION |
                   TSS_KEY_NOT_MIGRATABLE;
