Member Function Documentation

◆ close()

SINT32 CATLSClientSocket::close ( )

virtual

Shuts down the socket.

This is an overridden virtual function which shuts down the TLS layer first

Reimplemented from CASocket.

References CASocket::close(), m_bConnectedTLS, and m_pSSL.

Referenced by doTLSConnect(), CAAccountingBIInterface::initBIConnection(), CAAccountingBIInterface::terminateBIConnection(), and ~CATLSClientSocket().

◆ connect()

SINT32 CATLSClientSocket::connect	(	const CASocketAddr &	psa,
		UINT32	msTimeout
	)

virtual

Establishes the actual TCP/IP connection and performs the TLS handshake.

Establishes the TCP/IP connection, performs the TLS handshake and checks the server certificate validity.

Reimplemented from CASocket.

References CASocket::close(), CASocket::connect(), doTLSConnect(), and E_SUCCESS.

Referenced by CAAccountingBIInterface::initBIConnection().

◆ doTLSConnect()

SINT32 CATLSClientSocket::doTLSConnect ( const CASocketAddr & psa )

private

Does the TLS handshake.

The TCP Connection must be established first and openSSL library must be initialized

References close(), E_SUCCESS, E_UNKNOWN, CACertificate::getX509(), m_bConnectedTLS, m_pCtx, m_pRootCert, m_pSSL, CASocket::m_Socket, and CAMsg::printMsg().

Referenced by connect().

◆ receive()

SINT32 CATLSClientSocket::receive	(	UINT8 *	buff,
		UINT32	len
	)

virtual

Will receive some bytes from the socket.

May block or not depending on whatever this socket was set to blocking or non-blocking mode. Warning: If socket is in blocking mode and receive is called, receive will block until some data is available, EVEN IF AN OTHER THREAD WILL CLOSE THIS SOCKET!

Parameters

buff	the buffer which get the received data
len	size of buff

Returns: SOCKET_ERROR if an error occured

Return values

E_AGAIN,if	socket was in non-blocking mode and receive would block or a timeout was reached
0	if socket was gracefully closed

Returns: the number of bytes received (always >0)

Reimplemented from CASocket.

References E_AGAIN, len, m_pSSL, CAMsg::printMsg(), SOCKET_ERROR, and strerror().

◆ send()

SINT32 CATLSClientSocket::send	(	const UINT8 *	buff,
		UINT32	len
	)

virtual

Sends all data over the network.

This may block, until all data was sent.

Parameters

buff	the buffer of data to send
len	content length

Return values

E_UNKNOWN	if an error occured
E_SUCCESS	if successfull

Reimplemented from CASocket.

References E_AGAIN, E_SUCCESS, len, m_pSSL, CAMsg::printMsg(), SOCKET_ERROR, and strerror().

◆ sendFully()

SINT32 CATLSClientSocket::sendFully	(	const UINT8 *	buff,
		UINT32	len
	)

virtual

Sends all data over the network.

This may block, until all data was sent.

Parameters

buff	the buffer of data to send
len	content length

Return values

E_UNKNOWN	if an error occured
E_SUCCESS	if successfull

Reimplemented from CASocket.

References E_SUCCESS, E_UNKNOWN, len, and m_pSSL.

◆ setServerCertificate()

SINT32 CATLSClientSocket::setServerCertificate ( CACertificate * pCert )

Sets the Certifcate we accept as server identification.

Init the SSL object.

Set to NULL if you do not want any certificate checking. @Note At the moment only a depth of verification path of zero or one is supported!

SSL_init_library() must be called before this!
