tpfAppCryproCb

Crypto Callback function receiving the crypto related messages.

Parameters

[in]	u8MsgType	Crypto command about which the notification is received.
[in]	pvResp	A pointer to the result associated with the notification.
[in]	pvMsg	A pointer to a buffer containing the notification parameters (if any). It should be Casted to the correct data type corresponding to the notification type.
