From 8669f96663ab8f6e56184030ac46f9fc64ddbce5 Mon Sep 17 00:00:00 2001 From: Lucas Vieira Date: Sat, 21 Mar 2026 00:05:14 -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 TLS (withTlsCaCert, withTlsClientCert) and API key auth (withApiKey) builder methods to FilaClient. Uses grpc-java TlsChannelCredentials for TLS and a ClientInterceptor for Bearer token auth. Update admin.proto with API key and ACL management RPCs. All options are optional and backward compatible — plaintext without auth remains the default. --- README.md | 57 ++++ proto/fila/v1/admin.proto | 83 ++++++ .../dev/faisca/fila/ApiKeyInterceptor.java | 36 +++ src/main/java/dev/faisca/fila/FilaClient.java | 104 ++++++- .../java/dev/faisca/fila/BuilderTest.java | 47 ++++ src/test/java/dev/faisca/fila/TestServer.java | 256 +++++++++++++++++- .../dev/faisca/fila/TlsAuthClientTest.java | 99 +++++++ 7 files changed, 677 insertions(+), 5 deletions(-) create mode 100644 src/main/java/dev/faisca/fila/ApiKeyInterceptor.java create mode 100644 src/test/java/dev/faisca/fila/BuilderTest.java create mode 100644 src/test/java/dev/faisca/fila/TlsAuthClientTest.java diff --git a/README.md b/README.md index 67d97ef..13ccffb 100644 --- a/README.md +++ b/README.md @@ -44,6 +44,53 @@ try (FilaClient client = FilaClient.builder("localhost:5555").build()) { } ``` +## TLS + +Connect over TLS by providing a CA certificate.
