Confidential Computing API C++ Client Library

This directory contains an idiomatic C++ client library for the Confidential Computing API, a service to create challenges and verify attestation responses.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The quickstart/ directory contains a minimal environment to get started using this client library in a larger project. The following "Hello World" program is used in this quickstart, and should give you a taste of this library.

#include "google/cloud/confidentialcomputing/v1/confidential_computing_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace confidentialcomputing = ::google::cloud::confidentialcomputing_v1;
  auto client = confidentialcomputing::ConfidentialComputingClient(
      confidentialcomputing::MakeConfidentialComputingConnection());

  auto result = client.CreateChallenge(location.FullName(), {});
  if (!result) throw std::move(result).status();
  std::cout << result->DebugString() << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
