OpenID (and TypeKey) using native OpenSSL functions in PHP Posted on 15 Feb 2007 Update: fixed a flaw in my implementation I may have hinted at this a couple of times before, but now I'm actually saying something useful about it... I have a patch (php-openid.diff, for PHP 5, might also apply to PHP 4) for the openssl extension that makes it easier to build OpenID and TypeKey authentication support
