Secure Tcp .NET Component

Use the Secure Tcp component within the .NET Framework to communicate with any host using SSL over TCP. Features include:

Select SSL 2.0, SSL 3.0, PCT, TLS or unencrypted TCP communications.
Use in conjunction with the SslStream class to communicate using SSL.
Stream interface enables advanced read/write capabilities such as reading to a delimiter.
Send data synchronously or asynchronously.
Trace event exposes the TCP communication.
Design-time editor assists in protocol testing.
C# and VB.NET sample projects included.
Integrates with all versions of Visual Studio and supports C#, VB.NET, ASP.NET, Delphi 8, C# Builder, and other .NET compliant development environments.
Includes a royalty-free license!

Interface

Public Constructors
Tcp	Overloaded. Initialize a new instance of the Tcp class.
Public Properties
AutoReceive	Gets or sets a value which determines if data is automatically recieved.
Available	Gets the amount of data that has been received from the network and is available to be read.
Certificate	The Certificate object representing the certificate to use for optional client-side authentication.
Charset	Gets and sets the character set used for string/byte array conversions.
Connected	Gets the connected state of the connection.
ConnectTimeout	Gets or sets the number of milliseconds to wait for response from the server when connecting.
DoEvents	Gets or sets a value that controls the processing of events during blocking method calls.
Editor	In Visual Studio.NET, displays an interactive form to use to test real time protocol operations.
KeepAlive	Gets or sets the value of the socket's KeepAlive option.
LocalEndPoint	Returns the local address the socket is bound to.
NoDelay	Gets and sets a value the disables the use of Nagle's algorithm so that data is sent immediately.
OutOfBandInline	Gets or sets a value that indicates whether out-of-band (urgent) data is read as normal in-line data.
Proxy	Returns the Proxy instance that controls proxy server use.
ReceiveBufferSize	Gets and sets the size of the system receive buffer.
ReceiveTimeout	Gets and sets the number of milliseconds that a Tcp.Receive method will block before throwing a SocketException.
RemoteEndPoint	Returns the remote address/port the socket is connected to.
ReuseAddress	Gets or sets a value that typically allows any local port to be specified, even if it is already in use.
SecureProtocol	Gets or sets a value which determines the type of encryption to use on the data.
SendBufferSize	Gets and sets the size of the system send buffer.
SendTimeout	Gets and sets the number of milliseconds that a Tcp.Send method will block before throwing a SocketException.
Socket	Returns a reference to the System.Net.Sockets.Socket instance being used.
Stream	Returns a SegmentedStream that can be used for advanced streaming operations on the socket.
SynchronizingObject	Set this object to automatically control thread marshalling between worker threads and the main UI thread.
Tag	Gets or sets an object reference that can be used to associate this instance with any other.
UseAuthentication	Gets or sets a value that determines if certificate authentication is used.
UseSslShutdown	Controls whether or not shut-down bytes are sent to the server when the connection is closed.
Public Methods
BeginConnect	Overloaded. Connect to a server asynchronously, specifying the local interface and a range of local ports to use. The Tcp.EndConnect event is raised when completed.
BeginReceive	Overloaded. Receive data into your buffer asynchronously specifying a buffer, offset, size and SocketFlags value. The Tcp.EndReceive event is raised when completed.
BeginSend	Overloaded. Send data from your buffer asynchronously, specifying a buffer, offset, size and SocketFlags value. The Tcp.EndSend event is raised when completed.
Close	Overloaded. Close the connection.
Connect	Overloaded. Connect to a host, specifying the local interface and a range of local ports to use.
Receive	Overloaded. Receive data from the host, specifying a buffer, offset, size and SocketFlags value.
Send	Overloaded. Send data to the server, specifying a buffer, offset, size and SocketFlags value.
Public Events
CertificateReceived	This event is raised when a certificate has been received to be authenticated.
CertificateRequested	This event is raised when a certificate has been requested.
ConnectedChanged	Raised when the value of the Object.Connected property changes.
EndConnect	Raised when the Tcp.BeginConnect request completes.
EndReceive	Raised when the Tcp.BeginReceive request completes.
EndSend	Raised when the Tcp.BeginSend request completes.
RawTrace	Raised when data has been sent/received.
Trace	Raised when data has been sent/received.

Code Example

How easy is the Tcp component to use? Check out the VB.NET code below to see how easy-to-use the Tcp component is. This example demonstrates communicating with an echo server.

' Connect to an Echo server (typically port 7)
Tcp1.Connect("myserver", 7)

' Send some data
Tcp1.Send("test")

' Receive the echoed data
Dim seg as Segment = Tcp1.Receive()

' In the Echo protocol, the server waits until the client closes the connection.
Tcp1.Close()

' Display the data received (should be "test")
Debug.WriteLine(seg.ToString())
