LTI 1.3 Tool Library

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

This library is a fork of the packbackbooks/lti-1-3-php-library, patched specifically for use in Moodle.

It is currently based on version 5.2.1 of the packbackbooks/lti-1-3-php-library library.

The following changes are included so that the library may be used with Moodle:

• Replace the phpseclib dependency with openssl equivalent call in public key generation code.
• Replace the Guzzle dependency with generic HTTP client interfaces for client, response, exception.
• Small fix to http_build_query() calls, which now explicitly include the '&' arg separator param, for compatibility with applications that override PHP's arg_separator.output value via an ini_set() call, like Moodle does.

Please see the original README for more information about the upstream library.
