handshakes are based on eapol-key. The eapol-key structure is as follows:
PTK generation
To generate a PTK, five necessary elements are required: PMK, anonce (nonce 1), snonce (nonce 2), authenticate MAC (Mac 1), and supplicant MAC (MAC 2 ). For example:
The two nonce values are random numbers generated by authenticator and supplicant respectively.
The output of this topology contains four parts. In fact, data encr and data mic are combined as the

Embed sub-objects in our objects
There are several rules for sub-objects. A child object is treated as a "Base Object", and its vtable pointer must be the first real member of our object. For example, let's use our imicin sub-object as the base object, so that we define our object (we call it iaudiocard), embed the imicin sub-object to the first position, and then embed other sub-objects:
Typedef struct {imicin mic; // Our imicin (base) Sub-objec
