Akamai {OPEN} EdgeGrid Authentication for PHP

Note: in version 0.6.0 of the akamai-open/edgegrid-client it was moved to it's own repository, and the \Akamai\Open\EdgeGrid\Authentication library was seperated into the akamai-open/edgegrid-auth package (this repo).

This library implements the Akamai {OPEN} EdgeGrid Authentication scheme.

For more information visit the Akamai {OPEN} Developer Community.


This library requires PHP 5.3.9+, or HHVM 3.5+ to be used with the built-in Guzzle HTTP client.

PHP 5.3 has been end of life (EOL) since August 14th, 2014, and has known security vulnerabilities, therefore we do not recommend using it. However, we understand that many actively supported LTS distributions are still shipping with PHP 5.3.

To install, use composer:

$ composer require akamai-open/edgegrid-auth

Alternative Install: Single File (PHAR)

Alternatively, download the PHAR file from the releases page.

To use it, you just include it inside your code:

include 'akamai-open-edgegrid-auth.phar';

// Library is ready to use

Alternative Install: Git/Subversion/ZIP Archive

You can clone this repository using git, this repository using subversion, or download the latest ZIP archive or a specific release ZIP archive.

Using the Composer Autoloader

To use the composer autoloader, you must install the dependencies using:

$ composer install

Then include the autoloader:

require_once 'vendor/autoload.php';

Without Composer Autoloader

Include all the required classes manually in your code:

require_once 'src/Authentication.php';
require_once 'src/Authentication/Timestamp.php';
require_once 'src/Authentication/Nonce.php';
require_once 'src/Authentication/Exception.php';
require_once 'src/Authentication/Exception/ConfigException.php';
require_once 'src/Authentication/Exception/SignerException.php';
require_once 'src/Authentication/Exception/SignerException/InvalidSignDataException.php';


Once you have installed the library, you can create the header value by calling the appropriate \Akamai\Open\Edgegrid\Authentication::set*() methods. For example, using it with the built-in streams HTTP client might look like the following:

$auth = \Akamai\Open\EdgeGrid\Authentication::createFromEdgeRcFile('default', '/.edgerc');

$context = array(
	'http' => array(
		'header' => array(
			'Authorization: ' . $auth->createAuthHeader(),
			'Content-Type: application/json'

$context = stream_context_create($context);

$response = json_decode(file_get_contents('https://' . $auth->getHost() . $auth->getPath(), null, $context));
