From 9a2d35a9846a7fd81b196bed7cb3dd8e253ad198 Mon Sep 17 00:00:00 2001 From: Lucas Vieira Date: Sat, 21 Mar 2026 00:05:41 -0300 Subject: [PATCH 1/7] feat: add tls and api key authentication support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit add ca_cert, client_cert, client_key, and api_key parameters to both Client and AsyncClient. when ca_cert is provided, uses grpc secure channel with ssl credentials. when api_key is set, injects authorization bearer metadata via grpc interceptors. update admin.proto with api key and acl management messages. add integration tests for tls and api key auth. fully backward compatible — no auth/tls by default. --- README.md | 48 ++++++- fila/async_client.py | 102 ++++++++++++++- fila/client.py | 87 ++++++++++++- fila/v1/admin_pb2.py | 52 +++++--- fila/v1/admin_pb2.pyi | 110 +++++++++++++++- fila/v1/admin_pb2_grpc.py | 217 ++++++++++++++++++++++++++++++++ proto/fila/v1/admin.proto | 83 ++++++++++++ tests/conftest.py | 259 +++++++++++++++++++++++++++++++++++++- tests/test_client.py | 125 ++++++++++++++++++ 9 files changed, 1056 insertions(+), 27 deletions(-) diff --git a/README.md b/README.md index 8a4d189..826499b 100644 --- a/README.md +++ b/README.md @@ -46,9 +46,55 @@ async def main(): asyncio.run(main()) ``` +## TLS + +To connect over TLS, provide the CA certificate (and optionally client cert/key for mTLS): + +```python +from fila import Client + +# Read certificates. +with open("ca.pem", "rb") as f: + ca_cert = f.read() +with open("client.pem", "rb") as f: + client_cert = f.read() +with open("client-key.pem", "rb") as f: + client_key = f.read() + +# TLS only (server verification). +client = Client("localhost:5555", ca_cert=ca_cert) + +# Mutual TLS (client + server verification). +client = Client( + "localhost:5555", + ca_cert=ca_cert, + client_cert=client_cert, + client_key=client_key, +) +``` + +## API Key Authentication + +When the server has API key auth enabled, pass the key to the client: + +```python +from fila import Client + +client = Client("localhost:5555", api_key="fila_your_api_key_here") + +# Combined with TLS: +client = Client( + "localhost:5555", + ca_cert=ca_cert, + api_key="fila_your_api_key_here", +) +``` + +The API key is sent as `authorization: Bearer ` metadata on every RPC. + ## API -### `Client(addr)` / `AsyncClient(addr)` +### `Client(addr, *, ca_cert=None, client_cert=None, client_key=None, api_key=None)` / `AsyncClient(...)` Connect to a Fila broker.
