[Test status](https://github.com/bnsoftware/lti-1-3-php-library/actions/workflows/run_tests.yml/badge.svg?branch=master)

A library used for building IMS-certified LTI 1.3 tool providers in PHP.

This library allows a tool provider (your app) to receive LTI launches from a tool consumer (i.e. LMS). It validates LTI launches and lets an application interact with services like the Names Roles Provisioning Service (to fetch a roster for an LMS course) and Assignment Grades Service (to update grades for students in a course in the LMS).

This library was forked from [packbackbooks/lti-1p3-tool](https://github.com/packbackbooks/lti-1p3-tool) created by [Packback](https://packback.io), which was in turn forked from [IMSGlobal/lti-1-3-php-library](https://github.com/IMSGlobal/lti-1-3-php-library), initially created by @MartinLenord.

Installation
------------

[](#installation)

Run:

```
composer require bnsoftware/lti-1p3-tool
```

In your code, you will now be able to use classes in the `BNSoftware\Lti1p3` namespace to access the library.

### Configure JWT

[](#configure-jwt)

Add the following when bootstrapping your app.

```
Firebase\JWT\JWT::$leeway = 5;
```

### Implement Data Storage Interfaces

[](#implement-data-storage-interfaces)

This library uses three methods for storing and accessing data: cache, cookie, and database. All three must be implemented in order for the library to work. You may create your own custom implementations so long as they adhere to the following interfaces:

- `BNSoftware\Lti1p3\Interfaces\ICache`
- `BNSoftware\Lti1p3\Interfaces\ICookie`
- `BNSoftware\Lti1p3\Interfaces\IDatabase`

View the [Laravel Implementation Guide](https://github.com/bnsoftware/lti-1-3-php-library/wiki/Laravel-Implementation-Guide) to see examples (or copy/paste the code outright). Cache and Cookie storage have legacy implementations at `BNSoftware\Lti1p3\ImsStorage\` if you do not wish to implement your own. However, you must implement your own database.

### Create a JWKS endpoint

[](#create-a-jwks-endpoint)

A JWKS (JSON Web Key Set) endpoint can be generated for either an individual registration or from an array of `KID`s and private keys.

```
use BNSoftware\Lti1p3\JwksEndpoint;

// From issuer
JwksEndpoint::fromIssuer($database, 'http://example.com')->outputJwks();
// From registration
JwksEndpoint::fromRegistration($registration)->outputJwks();
// From array
JwksEndpoint::new(['a_unique_KID' => file_get_contents('/path/to/private/key.pem')])->outputJwks();
```
