Lukittu is a modern software licensing service that provides robust APIs to add an additional licensing layer to your software, enhancing security and trackability. This documentation contains all the information you need to get started.

Introduction

A product in Lukittu represents a software application that you want to manage access to. Through Lukittu's flexible access control system, each license key can grant access to one or multiple products.

Products

Licenses are the cornerstone of the Lukittu system, providing access control to your software. Without a valid license, users cannot access your software. License keys enable you to track software usage and prevent unauthorized access.

Licenses

Configuration settings for your Lukittu team.

Settings

Lukittu supports Stripe by automatically delivering licenses to customers via email upon purchase.

Stripe integration

Lukittu client-server communication employs a sophisticated hybrid cryptographic system that combines both asymmetric (RSA 2048) and symmetric encryption to ensure maximum security and integrity. This documentation provides a detailed overview of the communication processe

General overview

Overview of the Lukittu API documentation, including endpoints, request and response formats, parameters, and examples.

This endpoint is used to validate a license key with the Lukittu backend. Typically, you should call this endpoint when your software starts and act based on the response provided.

Important Note: If you are using a programming language that supports loading business logic code remotely (e.g., Java with a Remote ClassLoader), you should not use this endpoint. Instead, use the "classloader" endpoint for enhanced security.

License verify

The Heartbeat endpoint is used to determine whether a specific device is still active. You should call this endpoint at regular intervals (e.g., once every 30 minutes). This process also validates the license key in a similar way to the Verify License endpoint.

License heartbeat

The Classloader endpoint is used to download a release file. It is primarily intended for programming languages that support loading business logic code directly from a remote server into memory. For example, this is commonly used with Java classloaders.
