10. TLS/mTLS komunikacija

Scenariji: 4
FFI funkcije: ~30
Status: ⏳ Planirano

Ova kategorija obuhvaća sve scenarije za Post-Quantum sigurnu TLS komunikaciju. Postavljanje servera, konfiguracija klijenta i mTLS deployment.

Brzi početak koda

Kestrel Server (ASP.NET Core)

// Program.cs
var builder = WebApplication.CreateBuilder(args);
 
builder.WebHost.ConfigureKestrel(options =>
{
    options.ListenAnyIP(443, listenOptions =>
    {
        listenOptions.UseHttps(httpsOptions =>
        {
            // Učitavanje PQ certifikata
            var cert = ctx.LoadCertificate("server.crt.pem");
            var key = ctx.LoadPrivateKey("server.key.pem", password);
            httpsOptions.ServerCertificate = ctx.CreateX509Certificate2(cert, key);
 
            // Forsiranje TLS 1.3
            httpsOptions.SslProtocols = SslProtocols.Tls13;
 
            // Klijentski certifikat za mTLS
            httpsOptions.ClientCertificateMode = ClientCertificateMode.RequireCertificate;
            httpsOptions.ClientCertificateValidation = (cert, chain, errors) =>
            {
                return ctx.ValidateCertificate(cert, trustStore).IsValid;
            };
        });
    });
});

HttpClient s PQ-TLS

// Konfiguracija HttpClient-a za PQ-TLS
var handler = new SocketsHttpHandler
{
    SslOptions = new SslClientAuthenticationOptions
    {
        EnabledSslProtocols = SslProtocols.Tls13,
        RemoteCertificateValidationCallback = (sender, cert, chain, errors) =>
        {
            // PQ validacija certifikata
            return ctx.ValidateCertificate(cert, trustStore).IsValid;
        }
    }
};
 
var httpClient = new HttpClient(handler);
var response = await httpClient.GetAsync("https://pq-server.example.com/api/data");

OpenSSL 3.6 konfiguracija

# /etc/ssl/openssl.cnf

oqsprovider = oqsprovider_sect
 
[default_sect]
