Yet Another Infocard Java Based Infocard RP

AH!!! Hellooo world. Java based infocards are taking over... Here's Yet another Java Based Infocard Relying Party Demo. This time It's Ashish Jain's implementation of it. Ashish works for PingIdentity and is also the co-author of J2EE 1.4 Bible & Enterprise SOA (I bet you didnt need that introduction, as you would have known that already.).

His demo is available at pingidentity's Jetty Based demo server. His implementaion however does not use bouncycastle or XOM but is again a Java based RP developed from scratch using XMLBeans and XMLSEC.

It sure is a chweeth Object Oriented world aint it ??

UPDATE : There's one thing for sure that infocard and WS-\* is helping me with. IE: Making new connections and a LOT of new friends.

Infocard Invoker with Self Signed Server Certificates

A few folks have been having issues using self signed server certificates to invoke the Identity Selector WinFX Component. Here's a short walkthorough on how to use a self signed certificate and save a few $$$'s from having to but a Certificate from a Trusted Authority.

The key is to use the sha1rsa Signature Algorithm instead of using the default md5rsa Signature Algorithm.

openssl genrsa -des3 -out pass.key 1024
openssl rsa -in pass.key -out server.key
openssl req -new -x509 -days 365 -sha1 -newkey rsa:1024 -nodes -keyout server.key -out server.crt

Then copy the server.key and server.crt to your webservers config directory.
cp server.key /etc/httpd/conf/ssl.key/
cp server.crt /etc/httpd/conf/ssl.crt/

Change file access permissions
chmod go-rwx /etc/httpd/conf/ssl.key/server.key

Made a test cert
make testcert

Create a server.pem file as by concatenating the server.key file and the server.crt file as follows:
cat /etc/httpd/conf/ssl.key/server.key /etc/httpd/conf/ssl.crt/server.crt > /etc/httpd/conf/server.pem

restart your webserver.

Your self signed certificate should now invoke the identity selector without any issues...

NOTE : Remember folks. If youre learning anything at all from all of us who are blogging our experiences and processes about getitng infocard to work in all these various platforms and scenarios to PLEASE "pay it forward".

infocard xmlToken

nothing special here. This is what the xmlToken that the Identity Selector send across to a Relying Party looks like.

more soon...

Worlds FIRST Java Based infocard RP - LIVE

Chuck Mortimore has just deployed the world first Java Based Infocard Relying Party app. I'm following up soon with a PHP based Relying Party app... (Chuck beat me to it.. even though we've been constantly communicating and collaborating.. Guess Chuck's had the advantage of time... But However, We played tag-team and managed to get it to work !!!) Getting Java to work was easy.. PHP seems to be a bit harder with decoding and parsing encoded XML. I always thought that PHP was easier.. But was proven wrong this time... I'm trying to do exactly the same thing in PHP as the Java code and all I get is garbage. There must be something different in the urldecode / base64_decode functions in PHP and the way in which it handles "special characters".

HOWEVER: Chuck's the one who deserves 100% credit for deploying it first.

Kim, Please publish your code... not the relying party provider (RP) code, We got that already.. We would like to see the WinFx Identity Invoker Code... (please... please... please... please... please...)

For those who appreciate HARD WORK. Take a moment to toast Chuck. Infinite cheers Chuck !!! You ROCK !!!

Open Source rocks !!!..... Kim.. break down those walls. Let East Meet West. Let infocard be really "open". Please do not restrict us to work within those "infocard walled gardens"... please let us open up channels to securing the identity space. & ah !! in-ter-oh-por-ate !!

PS: When I say "us".. I mean "we the people", @the "open source community".... ;-)

John Doe's Infocard

LOL... had some time to kill..... and so I made a few images that you could use as your infocard image to help you identify the different infocards you create and distinguish between them instead of relying on the infocard super-imposed name.

And here's John Doe's Infocard. Use the password "password" to import the infocard.
This distribution of John Doe's infocard could probably make John Doe a "celebrity" again.

remember to save John Doe's infocard with the extention .crds

I know that most of the sites that would accept this card would also have a "confirm registration" email sent out. Well, I shall soon do something to address that too. The email address registered on this card is john.doe.infocard-AT-gmail-DOT-com. So, what I shall also do is setup gmail forward to forward all emails to, and then setup a blog to publish all those emails received. Well, then I could probably write a javascript or any utility to auto-click & confirm all url's in the posts, or to parse the contents of emails received and to a HTTPrequest.get() on all URL's that the blogpost contains. But since that would take some effort, and is not something I am too keen on doing anyway, and also since I currently do not have too much stale time on my hands, I shall do that only if I see the card being used... or I may also decide against it and keep this as "insider" info ;-)

Guess I would be wasting too much time on this. so the idea is now officially canned.

NOTE : This is in no way an attempt to initiate a world-wide attempt to present John Doe's infocard as a mechanism to break all web service's/application's that may someday accept infocard as it's auth medium. I received a few emails and phonecalls to clarify the intent here..
So Here's a public post of the intent. If you see that this can be used as a way in which tens of thousands of folks use a "common" credential (with User Control and Consent) to authenticate, and even deceive the "registration confirmation" system into accepting the credential, then I hope you see the big picture. These AuthN mediums are not for a person to person authentication system but for a "automated" system. I see this as a means in which hackers have a platform to authenticate into systems, initiate a new breed of DoS attacks, Hijack Identities, & misuse the system. Please see this not as an attempt to "attack" but as an attempt to show you that there can be several ways in which a system's stability can be compromised using extremely simple means. It does not require a rocket scientist to do such tasks. & mind you there are several folks "out there" who do this just for the kicks. So when you folks read about infocard and it's capabilities in all its basking glory, please remember not to tie yourselves down to a "infocard walled garden" and think outside of the BOX.
As "WE" work on securing the system/'s even more, the "outsiders" would always find innovative ways of breaking it. Therefore "WE" need to work as a "TEAM" and CO-LAB-OH-RATE!!
Please... Lets not work on "proprietorizing" IDENTITY. We got to have a solution that the industry sees as something that is SECURE, OPEN & more importantly INTER-OPERABLE. Remember it takes 2 to tango.

Internet Explorer 7 Build 5299 5296

UPDATE : Build 5299 did not work. I'm now hunting for Build 5296. Because the Build that works on my desktop is Build 5296. If anybody has a downloaded copy of Build 5296. Please please let me have a copy.....
OK. OK..... I've tried and tried and the march 20th release of ie7 just does not work (Kim had pre warned me/us about it, But I just didnt heed his advise.). The ONLY ie7 release that works with infocards is BUILD 5299 (for now). Now I had a desktop with Build 5299 installed, but unfortunately I had not saved a copy of it. I just finished rebuilding my virtual infocard test environment and was having a extremely hard time trying to download ie7 Build 5299. I desperately wanted Build 5299 for testing purposes. I am aware of all the security flaws that come along with it, but I just dont care about them for now. All I wanted is a browser that worked with infocards. So after much effort, I did find a ie7 Build 5299 download on rapidshare. So in case you would like to use ie7 Build 5299, here are the download links.
  1. IE 7 build 5299 (link 1)
  2. IE 7 build 5299 (link 2)
  3. IE 7 build 5299 (link 3)
WARNING: USE AT YOUR OWN RISK Also read the whole list of ie7 security flaws & vulnerabilities prior to proceeding.

UPDATE : Build 5299 did not work. I'm now hunting for Build 5296. Because the Build that works on my desktop is Build 5296. If anybody has a downloaded copy of Build 5296. Please please let me have a copy.....

infocard: An Expensive Affair

This " - night - Graveyard-shift " infocard project of mine is working out to be an expensive affair for me, in the $$ terms. I travel around so much (every mon-fri) that in order to work on it at nights, I needed to have WinXP with SP2 and ie7 on it. There's no way I would risk putting my endeared Ferarri through the BSoD (Blue Screen of Death) trauma. Well There was no way for me to carry all my desktops around when I travel. So came VMware to the rescue.

My VMWare Workstation costs US$199, and then another WinXP Pro license was another US$299. And another CD$100 for bribing my wife with a L'Occitane gift pack to entice her to let me spend this money. Whew!!.

I hope this expense pays off in terms of learning. I believe that there can be no cost factor associated with learning. And hope & pray that this pays off in the long run.

Now I have a "infocard" ready system in addition to a development environment, and a webserver with me all the time. Hopefully in the coming weeks, (with my new set of ammunition), I should be able to blog more on my discoveries...

So stay tuned...

User-Centric Identity Webcast

A FYI Reminer & a cross-post from superpatterns. The reason I'm crossposting this is because I believe that this is something important and something that everybody should participate in as the info that this webcast would provide you would prove extremely valuable.

There's a lot of buzz around 'user-centric identity' right now the notion of involving users in the management of their personal information and its use, rather than leaving it to some enterprise or other organization. The folks at the Liberty Alliance have written a whitepaper entitled 'Personal Identity' that shows how Liberty's Identity Federation Framework (ID-FF) and its successor SAML 2.0 can be used to implement user-centric identity for example, a user providing their own identity services via a Liberty-enabled device such as a cellphone. It's a good read. it starts from the basics, so you should be able to follow it even if you're new to Liberty and SAML.

vOn the same topic, John Kemp of Nokia and my esteemed colleague Hubert Le Van Gong will be presenting a webcast on April 12 2006 at 8am Pacific. PLEASE NOTE: Registration is required and limited to the first 100 respondents! The last webcast on the Liberty People Service 'sold out' very quickly, so get in there straight away if you're interested. If you're too late, don't despair - the webcast will be available in archive form after the event. I'll update this entry with the URL once it's online.

To register for the webcast, follow these steps.

  1. Go to
  2. Under the heading Attend a Meeting, click Register
  3. Search for centric
  4. Select User Centric Identity: Success Today and click on the Register Button. (Don't bother clicking on the link - it doesn't lead anywhere useful!)
  5. Fill out the required information and click Register Now at the bottom of the page.
Please email Tricia DeHart of the Liberty Alliance Project with any questions.
