Invites

SparkleShare can link to a host with a click of a button. It can open small xml files called invites that contain information on how to configure the client. When the user accepts an invite, SparkleShare is automatically configured to use a repository, and the user's public key is automatically uploaded.

When SparkleShare is running, it will open any file linked to with the sparkleshare://addProject/$URL protocol handler. For example, on a web page:

<a href="sparkleshare://addProject/http://path/to/the/invite.xml">Click here to add this project to SparkleShare</a>

Invites file names must end with .xml. Here's what an invite file looks like:

<?xml version="1.0" encoding="UTF-8"?>
<sparkleshare>
  <invite>
    <address>ssh://[email protected]/</address>
    <remote_path>/hbons/Stuff</remote_path>
    <fingerprint>16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48</fingerprint> // Optional
    <accept_url>https://www.sparkleshare.org/accept.php</accept_url> // Optional
    <announcements_url>tcp://notifications.sparkleshare.org:443</announcements_url> // Optional
  </invite>
</sparkleshare>

address The value normally typed into the Address field of the Add Remote Project dialog, with optional protocol and username.

remote_path The value normally typed into the Remote Path field of the Add Remote Project dialog.

fingerprint The host's fingerprint. Here's how you get it:

ssh-keygen -lf /etc/ssh/ssh_host_rsa_key.pub | cut --bytes=6-52

accept_url is the url SparkleShare sends the client's public key to using HTTP POST (in the variable name called public_key). You want to make sure this url is only valid for a short period of time and uses HTTP Secure. It's your host's task to make sure access is granted to this key. After this the host should return the HTTP OK (200) status, so SparkleShare can continue to fetching the repository.
