Coverage Status Build Status

This implements an ecryption socket based on the Noise Protocol Framtwork for vibe.D. The noise-c library is used to implement the Noise_XX_25519_ChaChaPoly_BLAKE2b protocol. libsodium is used for secure key memory management.

The API documentation is available here.

Note

  • This project will switch to the noise socket protocol once that has been formalized.
  • Currently targets vibe.D 0.7.x.
  • This implements a simple noise protocol without rekeying. This means after 2^64-1 messages a socket can no longer be used to send messages (an Exception will be thrown instead). This also means that long-running connections keep using the same key. If this temporary key gets compromised an attacker could decrypt the complete session.

A simple server/client example

import vibe.d, vibe.noise;

void main()
{
    createKeys("server.key", "server.pub");
    createKeys("client.key", "client.pub");

    server();
    runTask(&client);
    runEventLoop();
}

void client()
{
    auto stream = connectTCP("127.0.0.1", 4000);
    auto settings = NoiseSettings(NoiseKind.client);
    settings.privateKeyPath = Path("client.key");
    settings.remoteKeyPath = Path("server.pub");

    auto cryptStream = stream.createNoiseStream(settings);

    // Now use cryptStream as usual
}

void server()
{
    void onConnection(TCPConnection conn)
    {
        auto settings = NoiseSettings(NoiseKind.server);
        settings.privateKeyPath = Path("server.key");
        settings.verifyRemoteKey = (scope const(ubyte[]) remKey) {
            ubyte[KeyLength] pubKey;
            readPublicKey("client.pub", pubKey); 
            return remKey[] == pubKey[];
        };

        auto stream = conn.createNoiseStream(settings);

        // Now read/write data
    }

    listenTCP(4000, &onConnection);
}
