## Constructors

### FTPSClientSession

FTPSClientSession();

Creates an FTPSClientSession.

Passive mode will be used for data transfers.

### FTPSClientSession

explicit FTPSClientSession(
Context::Ptr pContext
);

Creates an FTPSClientSession using the given Context.

Passive mode will be used for data transfers.

### FTPSClientSession

FTPSClientSession(
const StreamSocket & socket,
bool readWelcomeMessage = true,
bool enableFTPS = true,
Context::Ptr pContext = nullptr
);

Creates an FTPSClientSession using the given connected socket for the control connection.

Passive mode will be used for data transfers.

### FTPSClientSession

FTPSClientSession(
const std::string & host,
Poco::UInt16 port = FTP_PORT,
const std::string & username = "",
const std::string & password = "",
Context::Ptr pContext = nullptr
);
