Infisical .NET 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.

• Nuget Package
• Github Repository

Deprecation Notice

All versions prior to 2.3.9 should be considered deprecated and are no longer supported by Infisical. Please update to version 2.3.9 or newer. All changes are fully backwards compatible with older versions.

Basic Usage

using Infisical.Sdk;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {

          ClientSettings settings = new ClientSettings
          {
            Auth = new AuthenticationOptions
            {
              UniversalAuth = new UniversalAuthMethod
              {
                ClientId = "your-client-id",
                ClientSecret = "your-client-secret"
              }
            }
          };


          var infisicalClient = new InfisicalClient(settings);

            var getSecretOptions = new GetSecretOptions
            {
                SecretName = "TEST",
                ProjectId = "PROJECT_ID",
                Environment = "dev",
            };
            var secret = infisicalClient.GetSecret(getSecretOptions);


            Console.WriteLine($"The value of secret '{secret.SecretKey}', is: {secret.SecretValue}");
        }
    }
}

This example demonstrates how to use the Infisical C# SDK in a C# application. The application retrieves a secret named TEST from the dev environment of the PROJECT_ID project.

We do not recommend hardcoding your Machine Identity Tokens. Setting it as an environment variable would be best.

Installation

$ dotnet add package Infisical.Sdk

Configuration

Import the SDK and create a client instance with your Machine Identity.

using Infisical.Sdk;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
          ClientSettings settings = new ClientSettings
          {
            Auth = new AuthenticationOptions
            {
              UniversalAuth = new UniversalAuthMethod
              {
                ClientId = "your-client-id",
                ClientSecret = "your-client-secret"
              }
            }
          };


          var infisicalClient = new InfisicalClient(settings); // <-- Your SDK client is now ready to use
        }
    }
}

ClientSettings methods

options · object

Show properties

ClientId · string · deprecated

Your machine identity client ID.

ClientSecret · string · deprecated

Your machine identity client secret.

AccessToken · string · deprecated

An access token obtained from the machine identity login endpoint.

CacheTtl · number · default: "300"

Time-to-live (in seconds) for refreshing cached secrets. If manually set to 0, caching will be disabled, this is not recommended.

SslCertificatePath

Optionally provide a path to a custom SSL certificate file. This can be substituted by setting the INFISICAL_SSL_CERTIFICATE environment variable to the contents of the certificate.

Auth · AuthenticationOptions

The authentication object to use for the client. This is required unless you’re using environment variables.

Authentication

The SDK supports a variety of authentication methods. The most common authentication method is Universal Auth, which uses a client ID and client secret to authenticate.

Universal Auth

Using environment variables

• INFISICAL_UNIVERSAL_AUTH_CLIENT_ID - Your machine identity client ID.
• INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET - Your machine identity client secret.

Using the SDK directly

ClientSettings settings = new ClientSettings
    {
      Auth = new AuthenticationOptions
      {
        UniversalAuth = new UniversalAuthMethod
        {
          ClientId = "your-client-id",
          ClientSecret = "your-client-secret"
        }
      }
    };

    var infisicalClient = new InfisicalClient(settings);

GCP ID Token Auth

Please note that this authentication method will only work if you’re running your application on Google Cloud Platform. Please read more about this authentication method.

Using environment variables

• INFISICAL_GCP_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

ClientSettings settings = new ClientSettings
  {
    Auth = new AuthenticationOptions
    {
      GcpIdToken = new GcpIdTokenAuthMethod
      {
        IdentityId = "your-machine-identity-id",
      }
    }
  };


  var infisicalClient = new InfisicalClient(settings);

GCP IAM Auth

Using environment variables

• INFISICAL_GCP_IAM_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.
• INFISICAL_GCP_IAM_SERVICE_ACCOUNT_KEY_FILE_PATH - The path to your GCP service account key file.

Using the SDK directly

ClientSettings settings = new ClientSettings
  {
    Auth = new AuthenticationOptions
    {
      GcpIam = new GcpIamAuthMethod
      {
        IdentityId = "your-machine-identity-id",
        ServiceAccountKeyFilePath = "./path/to/your/service-account-key.json"
      }
    }
  };


  var infisicalClient = new InfisicalClient(settings);

AWS IAM Auth

Please note that this authentication method will only work if you’re running your application on AWS. Please read more about this authentication method.

Using environment variables

• INFISICAL_AWS_IAM_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

ClientSettings settings = new ClientSettings
  {
    Auth = new AuthenticationOptions
    {
      AwsIam = new AwsIamAuthMethod
      {
        IdentityId = "your-machine-identity-id",
      }
    }
  };


  var infisicalClient = new InfisicalClient(settings);

Azure Auth

Please note that this authentication method will only work if you’re running your application on Azure. Please read more about this authentication method.

Using environment variables

• INFISICAL_AZURE_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

ClientSettings settings = new ClientSettings
  {
    Auth = new AuthenticationOptions
    {
      Azure = new AzureAuthMethod
      {
        IdentityId = "YOUR_IDENTITY_ID",
      }
    }
  };

  var infisicalClient = new InfisicalClient(settings);

Kubernetes Auth

Please note that this authentication method will only work if you’re running your application on Kubernetes. Please read more about this authentication method.

Using environment variables

• INFISICAL_KUBERNETES_IDENTITY_ID - Your Infisical Machine Identity ID.
• INFISICAL_KUBERNETES_SERVICE_ACCOUNT_TOKEN_PATH_ENV_NAME - The environment variable name that contains the path to the service account token. This is optional and will default to /var/run/secrets/kubernetes.io/serviceaccount/token.

Using the SDK directly

ClientSettings settings = new ClientSettings
  {
    Auth = new AuthenticationOptions
    {
      Kubernetes = new KubernetesAuthMethod
      {
        ServiceAccountTokenPath = "/var/run/secrets/kubernetes.io/serviceaccount/token", // Optional
        IdentityId = "YOUR_IDENTITY_ID",
      }
    }
  };

  var infisicalClient = new InfisicalClient(settings);

Caching

To reduce the number of API requests, the SDK temporarily stores secrets it retrieves. By default, a secret remains cached for 5 minutes after it’s first fetched. Each time it’s fetched again, this 5-minute timer resets. You can adjust this caching duration by setting the “cacheTTL” option when creating the client.

Working with Secrets

var options = new ListSecretsOptions
{
