<step id="GUID-4C65F526-6188-5957-9F2B-EC9C697C00D7"><cmd>Open a socket using

RSocket::Open() function and connect it with RSocket::Connect() function. </cmd>

<step id="GUID-3B20F63F-1CB8-5DA8-9228-5DD96EDC9C4B"><cmd/>

<info>Create a secure socket by calling CSecureSocket::NewL() function with

the parameters as socket and secure protocol name. </info>

</step>

<step id="GUID-200AFAD0-FE35-5213-9B26-CA4714F2FECC"><cmd/>

<info>To start the application acting as a client, use the CSecureSocket::StartClientHandshake()

function to initiate a handshake with the remote server. To start the application

acting as a server, use the CSecureSocket::StartServerHandshake() function. </info>

<info>The call completes with an error code, if the handshake fails. </info>

</step>

</steps>

<example><title>Secure Sockets example</title> <p>In the following example

iSocket is a reference to the already opened and connected socket and KSSLProtocol

is the descriptor containing the name of a protocol, in this case TLS1.0.

The function should return a pointer to the CSecureSocket. </p> <codeblock id="GUID-ADF8A6E8-87EB-5EB5-A224-0DAFC61FBD44" xml:space="preserve">

// Connect the socket server
