Detailed Description

Helper class defining an encrypted DTLS endpoint. Note that multiple connections are multiplexed onto a single DTLS socket.

Member Function Documentation

Accept()

ConnectResult AzNetworking::DtlsEndpoint::Accept	(	const DtlsSocket &	socket,
		const IpAddress &	address
	)

Accepts a connection from the remote encrypted endpoint.

Parameters

socket	the dtls socket being used for data transmission
address	the address of the remote endpoint connecting to us

Returns

a connect result specifying whether the connection is still pending, failed, or complete

Connect()

ConnectResult AzNetworking::DtlsEndpoint::Connect	(	const DtlsSocket &	socket,
		const IpAddress &	address,
		UdpPacketEncodingBuffer &	outDtlsData
	)

Opens a connection with the remote encrypted endpoint.

Parameters

socket	the dtls socket being used for data transmission
address	the address of the remote endpoint being connected to
outDtlsData	data buffer to store the dtls handshake packet

Returns

a connect result specifying whether the connection is still pending, failed, or complete

DecodePacket()

const uint8_t* AzNetworking::DtlsEndpoint::DecodePacket	(	UdpConnection &	connection,
		const uint8_t *	encryptedData,
		int32_t	encryptedSize,
		uint8_t *	outDecodedData,
		int32_t &	outDecodedSize
	)

If the endpoint has encryption enabled, this will decrypt the transmitted data and return the result.

Note

sizes have to be signed since OpenSSL often returns negative values to represent error results

Parameters

connection	the UDP connection being used for data transmission
encryptedData	the potentially encrypted data received from the socket
encryptedSize	the size of the received raw data
outDecodedData	an appropriately sized output buffer to store decrypted data
outDecodedSize	the size of the output buffer

Returns

pointer to the decoded data

IsConnecting()

bool AzNetworking::DtlsEndpoint::IsConnecting

(

)

const

Returns whether or not the endpoint is still negotiating the dtls handshake.

Returns

true if the endpoint is still in a connecting state

ProcessHandshakeData()

ConnectResult AzNetworking::DtlsEndpoint::ProcessHandshakeData	(	UdpConnection &	connection,
		const UdpPacketEncodingBuffer &	dtlsData
	)

Attempts to complete the dtls handshake and establish an encrypted connection.

Parameters

connection	the UDP connection being used for data transmission
dtlsData	data buffer containing dtls handshake packet

Returns

a connect result specifying whether the connection is still pending, failed, or complete
