Session-level TLS/SSL Settings

OnixS .NET FIX Engine provides an ability to localize TLS/SSL-related attributes to the bounds of a single FIX Session.

Per-session TLS/SSL settings can be accessed via the Ssl property.

Note

Per-session TLS/SSL settings are supported only for sessions-initiators. Session-acceptors can work only with global FIX Engine TLS/SSL settings.

For example:

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

// Stream FIX Session.
{
    const string streamSenderCompID = "str";
    var streamSession = new Session(streamSenderCompID, targetCompID, ProtocolVersion.Fix44)
    {
        Encryption = EncryptionMethod.Ssl
    };

    // If your counterparty performs the verification of your TLS/SSL certificate
    // you need to set the TLS/SSL Certificate File.
    string streamSslCertificateAndPrivateKeyFile = "str.pfx";
    streamSession.Ssl.CertificateLocation = streamSslCertificateAndPrivateKeyFile;

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

// Trading FIX Session.
{
    const string tradingSenderCompID = "tr";
    var tradingSession = new Session(tradingSenderCompID, targetCompID, ProtocolVersion.Fix44)
    {
        Encryption = EncryptionMethod.Ssl
    };

    string tradingSslCertificateAndPrivateKeyFile = "tr.pfx";
    // If your counterparty performs the verification of your TLS/SSL certificate
    // you need to set the TLS/SSL Certificate File.
    tradingSession.Ssl.CertificateLocation = tradingSslCertificateAndPrivateKeyFile;

    int tradingPort = 443;
    tradingSession.LogonAsInitiator(host, tradingPort, 30, true);
}
