When using the FeedTreeProxy, your RSS/Atom reader will see a small gray box appended to each feed item. This chunk of HTML is appended locally by the FeedTree software to tell you about the authenticity of the feed item in question.
Example: An RSS entry with a FeedTree security footer (gray box at bottom).
The icon and text in the footer describe the four possibilities when looking at any entry:
|http://feedtree.net/images/icons/download-32.png||The feed containing this entry was downloaded directly from the server via HTTP. This happens when you first subscribe to a feed, or if you're one of the few nodes volunteering to poll the feed for the benefit of the network. In this case, the entry is assumed to be authentic.|
|http://feedtree.net/images/icons/nosig-32.png||The feed was received from a FeedTree peer with no signature. This happens when other nodes in the network are polling this feed, and sharing the results with you. In this case, the authenticity of the entry cannot be established. It is possible (though, hopefully, unlikely) that someone has injected false data into the network.|
|http://feedtree.net/images/icons/signed-32.png||The feed was received from a FeedTree peer with a valid signature. This happens when you receive a feed entry that has been digitally signed with a key matching the publisher's certificate. In this case the message is guaranteed to be authentic.|
|http://feedtree.net/images/icons/badsig-32.png||The feed was received from a FeedTree peer with an invalid signature. This happens when you receive a feed entry that has been digitally signed, but the signature is broken in some way: either it does not match the publisher's certificate, or the data inside is corrupted or has been tampered with. In this case the message is not authentic and should not be trusted.|
