It allows integrating modules to encrypt and decrypt data in a standardized manner. It doesn't provide any user-facing features of its own, aside from administration pages to manage encryption profiles.

Gives automatic access to users if they are referenced somehow to this node.
It's scanning automatically for references with unlimited deep path, so you don't need to worry anymore how to configure your permissions correct, because it's checking for references automatically.

Example 1:
User 1 want to edit or delete Node 1, but the owner of this node is User 2.
But Node 1 have node reference (via nodereference) to profile of User 2 and User 2 have another reference (via userreference) to User 1. So that means that User 1 is referenced to that node, so give him access to edit it (you can customized other operations).
See following chart for example:
http://drupal.org/node/520062
Using with view_own module, you can disable view permission for users and enable them only through references.
