Member Function Documentation

void TcpConnection::freeSslClientKeyCert ( )

inlineinherited

Frees the memory used for the key and certificate pair.

Deprecated:: Use freeSslKeyCert() instead

void TcpConnection::freeSslKeyCert ( )

inlineinherited

Frees the memory used for the key and certificate pair.

void TcpConnection::setDestroyedDelegate ( TcpConnectionDestroyedDelegate destroyedDelegate )

inlineinherited

Sets a callback to be called when the object instance is destroyed.

Parameters

TcpServerConnectionDestroyedDelegate destroyedDelegate - callback

void TcpServer::setServerKeyCert ( const SslKeyCertPair & serverKeyCert )

inline

Adds SSL support and specifies the server certificate and private key.

Deprecated:: Use setSslKeyCert() instead

bool TcpConnection::setSslClientKeyCert	(	const uint8_t *	key,
		int	keyLength,
		const uint8_t *	certificate,
		int	certificateLength,
		const char *	keyPassword = `nullptr`,
		bool	freeAfterHandshake = `false`
	)

inlineinherited

Sets client private key, certificate and password from memory.

Deprecated:: Use setSslKeyCert(const uint8_t*, int, const uint8_t*, int, const char*, bool) instead

Note: This method makes copy of the data.

Parameters

const	uint8_t *keyData
int	keyLength
const	uint8_t *certificateData
int	certificateLength
const	char *keyPassword
bool	freeAfterHandshake

Returns: bool true of success, false or failure

bool TcpConnection::setSslClientKeyCert	(	const SslKeyCertPair &	clientKeyCert,
		bool	freeAfterHandshake = `false`
	)

inlineinherited

Sets client private key, certificate and password from memory.

Deprecated:: Use setSslKeyCert(const SslKeyCertPair&, bool) instead

Note: This method passes the certificate key chain by reference

Parameters

SSLKeyCertPair
bool	freeAfterHandshake

Returns: bool true of success, false or failure

bool TcpConnection::setSslKeyCert	(	const uint8_t *	key,
		int	keyLength,
		const uint8_t *	certificate,
		int	certificateLength,
		const char *	keyPassword = `nullptr`,
		bool	freeAfterHandshake = `false`
	)

inlineinherited

Server and Client certificates differ. Client certificate is used for identification. Server certificate is used for encrypt/decrypt the data. Make sure to use the correct certificate for the desired goal.

Note: This method makes copy of the data.

Parameters
