Detailed Description

Represents a Transport Data message

Constructor & Destructor Documentation

WireGuardTransportDataLayer() [1/2]

pcpp::WireGuardTransportDataLayer::WireGuardTransportDataLayer ( uint8_t *  data, size_t  dataLen, Layer *  prevLayer, Packet *  packet  )

inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in

WireGuardTransportDataLayer() [2/2]

pcpp::WireGuardTransportDataLayer::WireGuardTransportDataLayer	(	uint32_t	receiverIndex,
		uint64_t	counter,
		const uint8_t *	encryptedData,
		size_t	encryptedDataLen
	)

A constructor that creates a new Transport Data message

Parameters

[in]	receiverIndex	The receiver index
[in]	counter	The counter field
[in]	encryptedData	The encrypted data
[in]	encryptedDataLen	The length of the encrypted data
