IPC Broker

Secure Inter-Process Communication

A secure IPC framework providing authenticated message passing, access control, and robust communication channels between processes.

Features

• Authenticated Messaging: Identity verification (Token-based)
• Message Queuing: Reliable async messaging
• Request/Response: RPC-style communication
• Rate Limiting: DoS protection
• Timeouts: Configurable operation timeouts
• Robust Error Handling: Explicit error reporting and safe memory management

Planned Features (Roadmap)

• Encrypted Channels: TLS for sensitive data
• Service Discovery: Automatic endpoint discovery
• mTLS & Capability-Based Access

Quick Start

#include <ipc-broker/broker.h>

int main() {
    // Server side
    ipc_broker_t *broker = ipc_broker_new();
    
    ipc_service_t *service = ipc_service_create(broker, "my-service");
    ipc_service_register_handler(service, "echo", echo_handler, NULL);
    ipc_service_start(service);
    
    // Client side
    ipc_client_t *client = ipc_client_new(broker);
    ipc_client_connect(client, "my-service");
    
    ipc_message_t *msg = ipc_message_new("echo");
    ipc_message_set_payload(msg, "Hello", 5);
    
    ipc_message_t *reply = ipc_client_send(client, msg);
    
    return 0;
}
