WolfSSLDecryptVerifyCallback

```
public interface WolfSSLDecryptVerifyCallback
```
wolfSSL Decrypt/Verify callback interface. This interface specifies how applicaitons should implement the decrypt/ verify 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.setDecryptVerifyCb() method to be registered with the native wolfSSL library.

```
    Atomic record layer decrypt/verify callback method. This method acts as the decrypt/verify callback to be used with the wolfSSL atomic record layer processing.
    
    Parameters:
    
    ssl - the current SSL session object from which the callback was initiated.
    
    decOut - output buffer where the result of the decryption should be stored.
    
    decIn - the encrypted input buffer
    
    decSz - the size of the input buffer, decIn
    
    content - used with setTlsHmacInner(), the type of message
    
    verify - used with setTlsHmacInner(), specifies whether this is a verification of a peer message.
    
    padSz - output variable that should be set with the total value of the padding. When setting this, the first element of the the array should be used.
    
    ctx - user-registered decrypt/verify context
    
    Returns:
    
    0 upon success, otherwise a negative value on failure.
