		UInt16	primaryPort,
		const char *	secondaryHostName,
		UInt16	secondaryPort,
		const Logon &	logon,
		const char *	localNetworkInterface = ""
	)

Establishes the connection.

Note

Blocks until the logon reply is received.

Should be called only when Handler is disconnected.

Parameters

primaryHostName	Primary hostname to connect to.
primaryPort	Primary port number to connect to.
secondaryHostName	Secondary hostname to connect to.
secondaryPort	Secondary port number to connect to.

static std::string encryptPassword ( const std::string &  password, const std::string &  pubKeyPath  )

static

Encrypts the given password using the given key.

Parameters

password	Password to encrypt.
pubKeyPath	Path to the RSA public key file.

Returns

Encrypted and Base64-encoded password.

const std::string& licenseExpirationDate

void log	(	LogLevel::Enum	logLevel,
		const char *	logMessage
	)

Logs the given user-level message to the handler log.

void log	(	LogLevel::Enum	logLevel,
		const std::string &	str
	)

Logs the given user-level message to the handler log.
