WolfSSLMacEncryptCallback

```
public interface WolfSSLMacEncryptCallback
```
wolfSSL MAC Encrypt Callback Interface. This interface specifies how applicaitons should implement the MAC Encrypt callback class to be used by wolfSSL when using atomic record layer callbacks.
After implementing this interface, it should be passed as a parameter to the WolfSSLContext.setMacEncryptCb() method to be registered with the native wolfSSL library.

```
    Atomic record layer MAC Encrypt callback method. This method acts as the Atomic User Record Processing Mac/Encrypt callback to be used with the wolfSSL atomic record layer processing.
    
    Parameters:
    
    ssl - the current SSL session object from which the callback was initiated.
    
    macOut - output buffer where the result of the mac should be stored.
    
    macIn - the mac input buffer
    
    macInSz - the size of the mac input buffer, macIn
    
    macContent - used for setTlsHmacInner(), the type of message
    
    macVerify - used for setTlsHmacInner(), specifies whether this is a verification of a peer message.
    
    encOut - the output buffer where the result on the encryption should be stored.
    
    encIn - the input buffer to encrypt
    
    encSz - the size of the input buffer, encIn
    
    ctx - custom user context to be used
    
    Returns:
    
    0 upon success, otherwise a negative value on error.
