Hi,

I have successfully been able to program my key using the linux key personalizer and verified it with the ./ykdebug utility. I am now trying to configure the server and think I am doing all the right things but it doesnt want to cooperate.

I am hoping someone can help by showing me what I am doing wrong. Here is the programming of the key and the config file. Please show me what it should be based on the programmin og the key portion:
Code:
root@eee:~/yubikey-personalization-read-only# ./ykpersonalize -ouid=abc123
Passphrase to create AES key: secretstuff

What should the contents of this yubiphpbase config.php file be given the above:

Code:
/******* Erase this section after installation *******/
*

// OTP from your admin key you are to use to log in to KMS
// Eg. $otp = 'gklhtdkvrbfnbuicngergckgdfvfrbfjfhgiffghcithv';
$otp = '...enter yours...';

// Admin PIN as the 2nd factor of auth
//Eg. $pin = '12345678';

// This is the AES secret inside your key
// Eg. $aesParams['__ADM_KEY_SECRET__'] = '7Bs1Rl4Itr2+ZmbyO/KCWQ==';
$aesParams['__ADM_KEY_SECRET__'] = '.....enter yours.....';

We are assuming following parameters for hosting a Yubico Validation Server:

    1) Pin for two factor authentication : 12345
    2) AES secret Key: yubicovalidationserver (Base64 encoded output: eXViaWNvdmFsaWRhdGlvbnNlcnZlcg== )
    3) Random Secret: YubicoYubikey (Base64 encoded output: WXViaWNvWXViaWtleQ==)
    4) MySQL Database Server hostname: sql.test.com
    5) MySQL User name : yubico
    6) MySQL User password: test123
    7) MySQL Database name: yubikey
    8) Root Email Address: admin@test.com
    9) Apache http document root: /var/www/html

The content of yubiphpbase config.php based on above parameters would be:

Code:
<?php
/******************************************************
 *
 *      Customize EVERY parameter for your environment
 *
 ******************************************************/

//// AES secrets
//
$aesParams = array ();

/******* Erase this section after installation *******/
*

// OTP from your admin key you are to use to log in to KMS
// Eg. $otp = 'gklhtdkvrbfnbuicngergckgdfvfrbfjfhgiffghcithv';
$otp = 'vrkvfefuitvfiuibirllecjgbbnfhhirchithtvfrrbd';

// Admin PIN as the 2nd factor of auth
//Eg. $pin = '12345678';
$pin = '12345';

// This is the AES secret inside your key
// Eg. $aesParams['__ADM_KEY_SECRET__'] = '7Bs1Rl4Itr2+ZmbyO/KCWQ==';
$aesParams['__ADM_KEY_SECRET__'] = 'eXViaWNvdmFsaWRhdGlvbnNlcnZlcg==';

*
********** End of section to erase after installation *******/

// Make up a random secret to encrypt data in DB in b64 format
// Eg. $aesParams['__ENC_KEY_SECRET__'] = 'gklftrkvbvcbfhdafbedtjerrbbcgkuk';
$aesParams['__ENC_KEY_SECRET__'] = 'WXViaWNvWXViaWtleQ==';

//// DB, email and web related
//
$baseParams = array ();
$baseParams['__DB_HOST__'] = 'sql.test.com';   
$baseParams['__DB_USER__'] = 'yubico';
$baseParams['__DB_PW__'] = 'test123';
$baseParams['__DB_NAME__'] = 'yubikey';

// Eg. $baseParams['__ROOT_EMAIL__'] = 'support@yubico.com'; 
$baseParams['__ROOT_EMAIL__'] = 'admin@test.com';

$baseParams['__ORDER_URL__'] = 'http://yubico.com/products/order/';
$baseParams['__DOMAIN__'] = 'localhost';

// Eg. $baseParams['__DOC_ROOT__'] = '/apache/htdocs/'
$baseParams['__DOC_ROOT__'] = '/var/www/html';

//// Validation server
//

$valParams = array ();
$valParams['__VAL_URL__'] = 'http://localhost/wsapi/verify.php?id=';

//// HTML related
//
$headParams = array ();
$headParams['__SHORTCUT_ICON_URL__'] = 'http://localhost/kms/images/favicon.ico';

//// KMS admin activation welcome letter
//
$letterParams = array ();
$letterParams['__KMS_URL__'] = 'http://localhost/kms';

?>




As the AES key generated using the "ykpersonalize" tool is modhex encoded, we need to first decode (modhex decode) the AES key, then convert the decoded key to base64 encoded format and store it into the config.php file.

We are currently upgrading Yubico personalization tool and Yubico Management Server. The new versions would be released soon which would address all the above mentioned issues.

I assume $opt=""; is a key press of my earlier programmed key?

Assuming this I installed using these configs and get this in the kms.log file:

2008-12-20 22:10:00: OTP failed: Key authentication failed: Could not parse response, otp=ndnurjtddcgdfbcrhubneefdgikhrtuc12345 by 192.168.100.13

I even tried without the PIN concatinated and get the same:

2008-12-20 23:52:47: OTP failed: Key authentication failed: Could not parse response, otp=rguvvirtcdchgrkkkghbdvihgflivcgh by 192.168.100.13

ideas?

I tried

http://192.168.100.10/wsapi/verify_debu ... nfblfbhveu

and get:

Code:
<p>Debug> Invalid Yubikey gjndfgngdkkl
status=BAD_OTP
info=gjndfgngdkklvcjgebindtfivnenigdt
t=2008-12-21T18:00:36
<p>Debug> SIGN: info=gjndfgngdkklvcjgebindtfivnenigdt&status=BAD_OTP&t=2008-12-21T18:00:36
h=Ju1U9ETdOBgtxKqsO6x9B5EEyR0=


I also noticed that it does not appear to prepend the key identity to the otp (as seen by the following sequential keys):

Code:
jhblvdnekterkuddhrcniidnrkgvugbt
uebnhhnjlcrdgvdbghfjbkgnlbcjirti
nkktenriengnegdevcvrcfulindhtetv
undcvehjcngrkvegigerdljbngnkhhnb
tluitcffjrhbngidlnfbenthvgtgitbe


Did I program the key incorrectly I thought the 1st 12 characters were static??

In the yubiphpbase config.php file, we have to store a OTP generated from reprogrammed YubiKey.

The stored OTP in the config.php file must be 44 characters long (First 12 characters of Static ID + 32 characters of OTP)

The first 12 charectors of OTP representing static ID will be first decoded from modHAX and the decoded static ID will be encoded in base64 format and stored in Database.

adding the -ofixed seemed add the extra 12 chars at the front to make it 44, but still not luck


So it definately looks like they key programming if root cause. Is the following what would be correct for the above example to work? and set otp=to an output? or is the passphase aes key the other secret?

Code:
root@eee:~/yubikey-personalization-read-only# ./ykpersonalize -ouid=abc123 -ofixed=abc123
Passphrase to create AES key: yubicovalidationserver
Firmware version 1.3.0 Touch level 9376 Program sequence 24
fixed:hbhdheebedee
uid:hbhdheebedee
key:nfrrcjjhjnglvdtfktgctjcjfjulduig
acc_code:cccccccccccc
ticket_flags:APPEND_CR
config_flags:

We would appreciate if you can share following information with us.

    1) yubiphpbase config.php file
    2) Five OTPs generated from your YubiKey

This would help us to figure out a problem you are facing.

In order to successfully decrypt the OTP, AES key provided in the "config.php" file must be the one with which we have reprogrammed the YubiKey.

dion.rowney wrote:
// This is the AES secret inside your key
// Eg. $aesParams['__ADM_KEY_SECRET__'] = '7Bs1Rl4Itr2+ZmbyO/KCWQ==';
$aesParams['__ADM_KEY_SECRET__'] = 'eXViaWNvdmFsaWRhdGlvbnNlcnZlcg==';


Please replace "$aesParams['__ADM_KEY_SECRET__'] = 'eXViaWNvdmFsaWRhdGlvbnNlcnZlcg==';" with $aesParams['__ADM_KEY_SECRET__'] = 'tMwIhota8tSdUNgISOoudQ==';

This should solve the issue and Yubico Validation server should verify your OTP correctly.
We have successfully tested it in our test environment.

Please let us know if your are facing any further configuration problems.
