## A Word of Introduction

The Trust1Connector Javascript SDK is a library that functions as a proxy towards the Trust1Connector API. This Library does not contain any business logic and is a refernce implementation for the Trust1Connector API (HTTP/JSON).

{% hint style="warning" %}
Sample code uses ES6 language features such as arrow functions and promises. For compatibility with IE11, code written with these features must be either transpiled using tools like `Babel` or refactored accordingly using callbacks which are also available on the Trust1Connector Javascript SDK.
{% endhint %}

The Trust1Connector is a middleware which interacts with **hardware tokens** and **system certificate stores** (where certificates are stored and protected within the operating system).

### Trust1Connector's ambitions

The ambitions of the Trust1Connector is to:

* provide a **generic interface** to hardware tokens and smart cards
* operating **system agnostic** (works for all operating systems)
* **browser agnostic** (not depending on a browser plugin)
* facilitate the **onboarding** and **identity dematrialization**
* facilitate the derivation towards a **mobile identity**
* favours a decentralized approach and **privacy-first**
* facilitate user **authentication** and **digital signatures**
* facilitates identity information **validation** and **secured transport**
* favours a [**Zero-Knowledge**](https://en.wikipedia.org/wiki/Zero-knowledge_proof) approach
* exchange [**Verifiable Claims**](https://www.w3.org/TR/vc-data-model-2.0/)
