Detailed Description

Represents a Cookie Reply message

Constructor & Destructor Documentation

WireGuardCookieReplyLayer() [1/2]

pcpp::WireGuardCookieReplyLayer::WireGuardCookieReplyLayer ( 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

WireGuardCookieReplyLayer() [2/2]

pcpp::WireGuardCookieReplyLayer::WireGuardCookieReplyLayer	(	uint32_t	receiverIndex,
		const uint8_t	nonce[24],
		const uint8_t	encryptedCookie[32]
	)

A constructor that creates a new Cookie Reply message

Parameters

[in]	receiverIndex	The receiver index
[in]	nonce	The nonce field
