The Yubicloud PHP class is a subset of the multiOTP open source project.
Current build: 220.127.116.11 (2019-04-24)
No external file is needed (no PEAR, no PECL, no cURL).
You need a Yubico API key which is free if you have at least one Yubikey.
You can ask for your own key here: https://upgrade.yubico.com/getapikey/
$yubicloud = new Yubicloud("my_client_id", "my_secret_key");
$result = $yubicloud->checkOnYubiCloud($otp_to_check);
Possible returned value is one of the following:
OK The OTP is valid.
BAD_OTP The OTP is invalid format.
REPLAYED_OTP The OTP has already been seen by the service.
BAD_SIGNATURE The HMAC signature verification failed.
MISSING_PARAMETER The request lacks a parameter.
NO_SUCH_CLIENT The request id does not exist.
OPERATION_NOT_ALLOWED The request id is not allowed to verify OTPs.
BACKEND_ERROR Unexpected error in Yubico servers. Please contact them if you see this error.
NOT_ENOUGH_ANSWERS Server could not get requested number of syncs during before timeout.
REPLAYED_REQUEST Server has seen the OTP/Nonce combination before.
BAD_NONCE Answer Nonce is different from the request Nonce.
CONNECTION_ERROR Impossible to make a connection with the YubiCloud servers.
OTP_IS_DIFFERENT Answer OTP is different from request OTP.
OUT_OF_TIME_WINDOW Timestamp difference with the Yubico servers is bigger than yubicloud_max_time_window.
