Secure gRPC Logging Service with Mutual TLS in Golang

This project demonstrates building a secure gRPC server in Golang using mutual TLS (mTLS). The server supports producing and consuming in-memory logs, ensuring authenticated and encrypted communication between client and server.

Prerequisites

• protoc compiler: Install the Protocol Buffers compiler.
  • On macOS:

    brew install protobuf

  • On Linux (Ubuntu):

    sudo apt install -y protobuf-compiler

  • On Windows: Download from the Protocol Buffers releases.

Installing Dependencies

Run the following command to install all project dependencies:

go mod tidy

Project Structure

• spec/: Protocol Buffers file defining gRPC service and messages
• cert/: Directory for ca configs and certificates requests
• log/: logging functionality implementation in Go
• server/: gRPC server implementation in Go
• config/: Configurations for mutual TLS

Running the Project

1. Compile protocol buffers

make compile

2. Initialize certificates storing directory

make init

3. Generate certificates

make gencert

4. Test the mutula TLS

make test
