Per-session SSL Settings

The OnixS C++ FIX Engine provides an ability to localize SSL-related attributes to the bounds of a single FIX Session. Per-session SSL settings can be accessed using OnixS::FIX::Session::setSslCertificateFile and OnixS::FIX::Session::setSslPrivateKeyFile members of the OnixS::FIX::Session class.

Example

const string targetCompID = "CNX"; 
const string host = "TargetHost"; 

// Stream FIX Session.
{ 
        const string streamSenderCompID = "str"; 
        const string streamSslCertificateAndPrivateKeyFile = "str.pem"; 
        
    ISessionListener listener;  
        Session streamSession(streamSenderCompID, targetCompID, FIX_42, &listener); 
    streamSession.setEncryptionMethod(Session::SSL); 

    // If your counterparty performs the verification of your SSL certificate 
    // you need to set both SSL Certificate File and SSL Private Key File.

        streamSession.setSslCertificateFile(streamSslCertificateAndPrivateKeyFile);
        streamSession.setSslPrivateKeyFile(streamSslCertificateAndPrivateKeyFile);

        const int streamPort = 442;
        streamSession.logonAsInitiator(host, streamPort, 30, true);

        std::clog << "Stream session is established." << std::endl;

        streamSession.logout();
}

// Trading FIX Session.
{ 
        const string tradingSenderCompID = "tr"; 
        const string tradingSslCertificateAndPrivateKeyFile = "tr.pem";

    ISessionListener listener;  
        Session tradingSession(tradingSenderCompID, targetCompID, FIX_42, &listener);
        tradingSession.setEncryptionMethod(Session::SSL); 

    // If your counterparty performs the verification of your SSL certificate 
    // you need to set both SSL Certificate File and SSL Private Key File.

        tradingSession.setSslCertificateFile(tradingSslCertificateAndPrivateKeyFile);
        tradingSession.setSslPrivateKeyFile(tradingSslCertificateAndPrivateKeyFile);

        const int tradingPort = 443;
        tradingSession.logonAsInitiator(host, tradingPort, 30, true);

        std::clog << "Trading session is established." << std::endl;

        tradingSession.logout();
}
