swarmauri_transport_tls_unicast 0.1.0.dev9

TLS / mTLS unicast transport for Swarmauri.

Swarmauri TLS Unicast Transport

The Swarmauri TLS Unicast Transport brings encrypted, authenticated connections to the unified transport lifecycle. It wraps asyncio's TLS streams with the .server(...) / .client(...) contexts so you can safely manage secure sockets directly from the transport.

Installation

Using uv

uv add --directory pkgs/standards/swarmauri_transport_tls_unicast swarmauri_transport_tls_unicast

Using pip

pip install swarmauri_transport_tls_unicast

Usage

The snippet below demonstrates creating a mutually-authenticated TLS echo server and client.

import asyncio
import ssl
from swarmauri_transport_tls_unicast import TlsUnicastTransport

srv_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
srv_ctx.load_cert_chain("srv.pem", "srv.key")
# srv_ctx.verify_mode = ssl.CERT_REQUIRED
# srv_ctx.load_verify_locations("ca.pem")

cli_ctx = ssl.create_default_context()
# cli_ctx.load_cert_chain("cli.pem", "cli.key")

async def main():
    server = TlsUnicastTransport(srv_ctx)

    async def run_server():
        async with server.server(host="0.0.0.0", port=8443):
            data = await server.recv()
            await server.send("peer", b"tls:" + data)

    async def run_client():
        client = TlsUnicastTransport(cli_ctx, sni="localhost")
        async with client.client(host="127.0.0.1", port=8443):
            await client.send("server", b"hello")
            response = await client.recv()
            print(response.decode())

    await asyncio.gather(run_server(), run_client())

asyncio.run(main())

Configure the SSL contexts with your own certificates (and CA trust) to enable TLS or full mTLS verification.
