txopenid is an identity provider for OpenID version 1.1. That is, it  
can provide credentials for sites that accept OpenID logins, based on  
data stored in a MySQL database.

It won't currently help you *accept* OpenID as an authentication  
mechanism, but it's a great provider, IMNSHO ;-) I use it as my  
identity provider, and so far it works well for my purposes. It also  
has been pleasantly stable the whole time I've been running it (at  
least as monitored by Nagios).

Also, it provides a number of utility functions that are essential to  
the OpenID spec which should make writing a consumer a bit easier  
(particularly in regards to hmac digest support and encoding integers  
into their big-endian two's complement as a binary string...ugh)...

Admittedly OpenID is at version 2.x these days, so I'm hoping soon to  
update the provider and/or write a consumer implementation. I'd like  
to think OpenID is finally starting to catch on...
