http://openid4.me/ -- OpenId ♥ foaf+ssl
OpenId4.me is the bridge between foaf+ssl and OpenId we have been waiting for.
OpenId and foaf+ssl have a lot in common:
- They both allow one to log into a web site without requiring one to divulge a password to that web site
- They both allow one to have a global identifier to log in, so that one does not need to create a username for each web site one wants to identify oneself at.
- They also allow one to give more information to the site about oneself, automatically, without requiring one to type that information into the site all over again.
OpenId4.me allows a person with a foaf+ssl profile to automatically login to the millions of web sites that enable authentication with OpenId. The really cool thing is that this person never has to set up an OpenId service. OpenId4.me does not even store any information about that person on it's server: it uses all the information in the users foaf profile and authenticates him with foaf+ssl. OpenId4.me does not yet implement attribute exchange I think, but it should be relatively easy to do (depending on how easy it is to hack the initial OpenId code I suppose).
If you have a foaf+ssl cert (get one at foaf.me) and are logging into an openid 2 service, all you need to type in the OpenId box is openid4.me. This will then authenticate you using your foaf+ssl certificate, which works with most existing browsers without change!
If you then want to own your OpenId, then just add a little html to your home page. This is what I placed on http://bblfish.net/:
<link rel="openid.server" href="http://openid4.me/index.php" />
<link rel="openid2.provider openid.server" href="http://openid4.me/index.php"/>
<link rel="meta" type="application/rdf+xml" title="FOAF" href="http://bblfish.net/people/henry/card%23me"/>
And that's it. Having done that you can then in the future change your openid provider very easily. You could even set up your own OpenId4.me server, as it is open source.

Note on comments:
- I know the forms below are a little small. We have asked for years for this to be changed, but I don't think it's going to happen soon. In Apple's Safari you can resize the entry box with you mouse. For people using other browsers click on this javascript link, that should allow you to resize your form.
- Comments are moderated, so they will take a little time to appear. Currently moderation means I have to read them personally. Hopefully with OpenId deployment, this will become more automated.
- HTML markup no longer works here, due to some decision made somewhere. Sorry about that.
- If you are having trouble posting, it may be that you need javascript to be enabled. I don't think javascript should be needed for submitting a form, but that's the way it is here.

This is huge ! Just tested with identi.ca.
I'm looking forward to using it in my apps.
