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

Basic Usage

package com.example.app;

import com.infisical.sdk.InfisicalClient;
import com.infisical.sdk.schema.*;

public class Example {
    public static void main(String[] args) {
        // Create a new Infisical Client
        ClientSettings settings = new ClientSettings();
        settings.setClientID("MACHINE_IDENTITY_CLIENT_ID");
        settings.setClientSecret("MACHINE_IDENTITY_CLIENT_SECRET");
        settings.setCacheTTL(Long.valueOf(300)); // 300 seconds, 5 minutes

        InfisicalClient client = new InfisicalClient(settings);

        // Create the options for fetching the secret
        GetSecretOptions options = new GetSecretOptions();
        options.setSecretName("TEST");
        options.setEnvironment("dev");
        options.setProjectID("PROJECT_ID");

        // Fetch the sercret with the provided options
        GetSecretResponseSecret secret = client.getSecret(options);

        // Print the value
        System.out.println(secret.getSecretValue());

        // Important to avoid memory leaks!
        // If you intend to use the client throughout your entire application, you can omit this line.
        client.close();
    }
}

This example demonstrates how to use the Infisical Java SDK in a Java 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

The Infisical Java SDK is hosted on the GitHub Packages Apache Maven registry. Because of this you need to configure your environment properly so it’s able to pull dependencies from the GitHub registry. Please check this guide from GitHub on how to achieve this. Our package is located here. Please follow the installation guide on the page.

Configuration

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

import com.infisical.sdk.InfisicalClient;
import com.infisical.sdk.schema.*;

public class App {
    public static void main(String[] args) {

        ClientSettings settings = new ClientSettings();
        settings.setClientID("MACHINE_IDENTITY_CLIENT_ID");
        settings.setClientSecret("MACHINE_IDENTITY_CLIENT_SECRET");

        InfisicalClient client = new InfisicalClient(settings); // Your client!
    }
}

ClientSettings methods

options

object

Show properties

setClientID()

string

Your machine identity client ID.

setClientSecret()

string

Your machine identity client secret.

setAccessToken()

string

An access token obtained from the machine identity login endpoint.

setCacheTTL()

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.

setSiteURL()

string

default:"https://app.infisical.com"

Your self-hosted absolute site URL including the protocol (e.g. https://app.infisical.com)

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

client.listSecrets(options)

ListSecretsOptions options = new ListSecretsOptions();
options.setEnvironment("dev");
options.setProjectID("PROJECT_ID");
options.setPath("/foo/bar");
options.setIncludeImports(false);

SecretElement[] secrets = client.listSecrets(options);

Retrieve all secrets within the Infisical project and environment that client is connected to

setAttachToProcessEnv()

boolean

setIncludeImports()

boolean

Whether or not to include imported secrets from the current path. Read about secret import

client.getSecret(options)

GetSecretOptions options = new GetSecretOptions();
options.setSecretName("TEST");
options.setEnvironment("dev");
options.setProjectID("PROJECT_ID");

GetSecretResponseSecret secret = client.getSecret(options);

String secretValue = secret.getSecretValue();

Retrieve a secret from Infisical. By default, getSecret() fetches and returns a shared secret.
