The Yubico authentication PHP class provides an easy way to integrate the Yubikey into your existing PHP-based user authentication infrastructure. Installation is simple using PEAR.
The development community is co-ordinated via the Github project.
Make sure your PHP installation supports curl, and that you have installed PEAR. On Debian/Ubuntu systems:
$ apt-get install libapache2-mod-php5 php5-curl php-pear
Install the component by invoking:
$ wget https://developers.yubico.com/php-yubico/Releases/Auth_Yubico-2.5.tgz $ pear install Auth_Yubico-2.5.tgz

Note
|
Make sure that you have read Using a YubiKey OTP library before continuing. |
This is an example of how you can use the Yubico.php inside an HTML *.php file:
<?php
require_once 'Auth/Yubico.php';
$otp = "ccbbddeertkrctjkkcglfndnlihhnvekchkcctif";
# Generate a new id+key from https://upgrade.yubico.com/getapikey
$yubi = new Auth_Yubico('42', 'FOOBAR=');
$auth = $yubi->verify($otp);
if (PEAR::isError($auth)) {
print "<p>Authentication failed: " . $auth->getMessage();
print "<p>Debug output from server: " . $yubi->getLastResponse();
} else {
print "<p>You are authenticated!";
}
?>There is also a complete example site that demonstrates one-factor and two-factor mode. It requires a database to store the username and passwords. Database schema is in example/db.sql and configuration for the database needs to go into example/config.php.
The example site is deployed here.
This package also includes Modhex_Calculator.php, a web page illustrating how to work with the modhex encoding. It is deployed here
