M9Studio.SecureStream

Encrypted session abstraction with TLS 1.3-style handshake and AES-GCM transport encryption.

NuGet License: Apache-2.0

Features

  • Pluggable transport adapter (ISecureTransportAdapter<TAddress>) to abstract over sockets, in-memory channels, etc.
  • X25519-based handshake and key agreement
  • AES-GCM symmetric encryption with integrity and confidentiality
  • Agnostic to transport and address types (can use IPEndPoint, int, etc.)
  • Designed to resemble lightweight TLS tunnel

Installation

dotnet add package M9Studio.SecureStream

Usage

Setup and connection

var adapter = new MyTransportAdapter();
var manager = new SecureChannelManager<MyAddressType>(adapter);

manager.OnSecureSessionEstablished += session =>
{
    session.Send(Encoding.UTF8.GetBytes("Hello securely"));
    var response = session.Receive();
    Console.WriteLine("Decrypted: " + Encoding.UTF8.GetString(response));
};

var session2 = manager.Connect(remoteAddress);
session2.Send(Encoding.UTF8.GetBytes("Hello securely"));
var response2 = session2.Receive();
Console.WriteLine("Decrypted: " + Encoding.UTF8.GetString(response2));

Interface

ISecureTransportAdapter<TAddress>

This interface abstracts the transport layer for sending and receiving encrypted data. You can implement it over any transport: UDP, TCP, or even in-process queues.

public interface ISecureTransportAdapter<TAddress>
{
    event Action<TAddress> OnConnected;
    event Action<TAddress> OnDisconnected;

    bool SendTo(byte[] buffer, TAddress remote);
    byte[] ReceiveFrom(TAddress remote);
}
  • OnConnected: triggered when a remote peer becomes reachable (e.g., after initial handshake packet is received)
  • OnDisconnected: triggered when a remote peer is no longer available or manually closed
  • SendTo: sends a raw encrypted packet to the given address
  • ReceiveFrom: blocks until a packet is received from the specified address
