Yubikey PHP class is a GNU LGPL class to check a YubiKey authentication locally
(c) 2014-2015 SysCo systemes de communication sa
The Yubikey PHP class is a subset of the multiOTP open source project.
http://www.multiOTP.net/
Current build: 4.3.2.0 (2015-01-04)
No external file is needed (no PEAR, no PECL).
AES 128 encryption and decryption algorithms using pure PHP code (LGPLv2.1) from Jose Manuel Busto Lopez is directly integrated in the source code.
In Yubico OTP mode, when the YubiKey button is pressed, the returned string is 44 characters long, with 12 characters for the fixed public id, and 32 characters for the dynamic OTP part. With the 12 characters of the public id, the right AES key (the secret) can be retrieved from your user identification handler to decrypt the dynamic OTP part.
<?php
require_once('yubikey.class.php');
$yubikey = new Yubikey();
$result = $yubikey->checkYubicoOtp($yubico_modhex_encrypted_part,
$secret,
$last_valid_position);
?>
OK The OTP is valid.
BAD_OTP The OTP is invalid format.
REPLAYED_OTP The OTP has already been used.
