# Infisical C++ SDK

If you're working with C++, the official Infisical C++ SDK package is the easiest way to fetch and work with secrets for your application.

## Compatible with C++ 17 and later

The Infisical C++ SDK is compatible with C++ 17 capable compilers. This implies GCC 8 or newer, and clang 3.8 or newer. Earlier versions of C++ are unsupported.

## Dependencies

* `cURL`: Used internally for crafting HTTP requests.

## CMake Installation

```bash  theme={"dark"}
cmake_minimum_required(VERSION 3.14)
project(InfisicalTest)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_PREFIX_PATH ${CMAKE_BINARY_DIR})

find_package(OpenSSL REQUIRED)


include(FetchContent)


FetchContent_Declare(
  infisical
  GIT_REPOSITORY https://github.com/Infisical/infisical-cpp-sdk.git
  GIT_TAG 1.0.0 # Replace with the desired version
)

FetchContent_MakeAvailable(infisical)
FetchContent_GetProperties(infisical)


# Example usage. This will differ based on your project structure.
add_executable(my_app src/main.cpp)
target_link_libraries(my_app PRIVATE infisical OpenSSL::SSL OpenSSL::Crypto)
target_include_directories(my_app PRIVATE ${infisical_SOURCE_DIR}/include)
```

## Manual Installation

If you're unable to use the recommended CMake installation approach, you can choose to manually build the library and use it in your project.

```bash  theme={"dark"}
mkdir build
cd build
cmake ..
make
```

## Quick-Start Example

Below you'll find an example that uses the Infisical SDK to fetch a secret with the key `API_KEY` using [Machine Identity Universal Auth](https://infisical.com/docs/documentation/platform/identities/universal-auth)

More examples can be found in the [/examples](https://github.com/Infisical/infisical-cpp-sdk/tree/main/examples) folder.

```cpp  theme={"dark"}
#include <iostream>
#include <libinfisical/InfisicalClient.h>

int main() {

  try {
    Infisical::InfisicalClient client(
        Infisical::ConfigBuilder()
            .withHostUrl("https://app.infisical.com") // Optionally change this to your custom Infisical instance URL.
            .withAuthentication(
                Infisical::AuthenticationBuilder()
                    .withUniversalAuth("<machine-identity-universal-auth-client-id>", "<machine-identity-universal-auth-client-secret>")
                    .build())
            .build());

    const auto getSecretOptions = Infisical::Input::GetSecretOptionsBuilder()
                                      .withEnvironment("<env-slug>") // dev, staging, prod, etc
                                      .withProjectId("<your-project-id>")
                                      .withSecretKey("API_KEY")
                                      .build();

    const auto apiKeySecret = client.secrets().getSecret(getSecretOptions);

    printf("Secret retrieved, [key=%s] [value=%s]\n", apiKeySecret.getSecretKey().c_str(), apiKeySecret.getSecretValue().c_str());
  } catch (const Infisical::InfisicalError &e) {
    std::cerr << "Error: " << e.what() << std::endl;
    return 1;
  }

  return 0;
}
```

## JSON Serialization

The SDK uses [nlohmann/json](https://github.com/nlohmann/json) internally to serialize/deserialize JSON data. This SDK makes no assumptions about which JSON library you use in your project, and you aren't constrained to `nlohmann/json` in any way. Data returned by the SDK is returned as a class, which exposes Getter methods for getting fields such as the secret value or secret key.

## Documentation

The Infisical C++ SDK follows a builder pattern for all types of input. Below is a detailed documentation of our currently support methods.

Everything related to the Infisical SDK lives inside the `Infisical` namespace.

### InfisicalClient Class

`InfisicalClient(Config &config)`

```cpp  theme={"dark"}
  Infisical::InfisicalClient client(
      Infisical::ConfigBuilder()
          .withHostUrl("https://app.infisical.com")
          .withAuthentication(
              Infisical::AuthenticationBuilder()
                  .withUniversalAuth(clientId, clientSecret)
                  .build())
          .build());
```

Config is created through the `ConfigBuilder` class. See below for more details

### Config Class

`Config` defines the configuration of the Infisical Client itself, such as authentication.

```cpp  theme={"dark"}
Infisical::Config config = Infisical::ConfigBuilder()
                          .withHostUrl("https://app.infisical.com")
                          .withAuthentication(
                            Infisical::AuthenticationBuilder()
                              .withUniversalAuth(clientId, clientSecret)
                              .build())
                          .build();

Infisical::InfisicalClient client(config);
```

* `withHostUrl(string)` *(optional)*: Specify a custom Infisical host URL, pointing to your Infisical instance. Defaults to `https://app.infisical.com`
* `withAuthentication(Infisical::Authentication)`: Configure the authentication that will be used by the SDK. See [Authentication Class](#authentication-class) for more details.
* `build()`: Returns the `Config` object with the options you configured.

### Authentication Class

```cpp  theme={"dark"}
Infisical::Authentication auth = Infisical::AuthenticationBuilder()
                                  .withUniversalAuth(clientId, clientSecret)
                                  .build();

Infisical::Config config = Infisical::ConfigBuilder()
                            .withAuthentication(std::move(auth)) // Or use inline declaration
                            .build();
```

* `withUniversalAuth(string, string)`: Specify the Universal Auth Client ID and Client Secret that will be used for authentication.
* `build()`: Returns the `Authentication` object with the options you specified.

### TSecret Class

The `TSecret` class is the class that's returned by all secret methods (get/list/delete/update/create). It can come in the form of a `std::vector` or a single instance.

**Available getter methods:**

* `getId(): std::string`: Returns the ID of the secret.
* `getWorkspace(): std::string`: Returns the project ID of the secret.
* `getEnvironment(): std::string`: Returns the environment slug of the secret.
* `getVersion(): unsigned int`: Gets the version of the secret. By default this will always be the latest version unless specified otherwise with `withVersion()`
* `getType(): std::string`: Returns the type of the secret. Can only be `shared` or `personal`. Shared secrets are available to everyone with access to the secret. Personal secrets are personal overwrites of the secret, mainly intended for local development purposes.
* `getSecretKey(): std::string`: Returns the secret key.
* `getSecretValue(): std::string` Returns the secret value.
* `getRotationId(): std::string`: If the secret is a rotation secret, this will return the rotation ID of the secret. If it's a regular secret, this will return an empty string.
* `getSecretPath(): std::string`: Returns the secret path of the secret.
* `getSkipMultilineEncoding(): bool`: Returns whether or not skip multiline encoding is enabled for the secret or not.
  `getIsRotatedSecret(): bool`: Returns wether or not the secret is a rotated secret. If `true`, then `getRotationId()` returns the ID of the rotation.
