xorkeeauth supports a simple API interface the application can use to get its users to authenticate themselves and to also authorize small portions of data like a transaction.
In fact it is so simple that this page gives you the means of acting as an application and demonstrate how the authentication works.
To try this you should have a xorkee handle and its key available with you. Simplest will be if you have a smart phone based key. Though DSC tokens will also work.
Create a key and get a xorkee handle for yourself.
