Hi,
I looks to be a good idea, but i'll always encounter problem to share the key. The better ways is to share the right via
AuthorizationExternalForm but I can't find a ways to send it to the Agent. After sending the key (at the same time as the right), your ways looks great.
If someone know how to send AuthorizationExternalForm...
Thanks in advance
Vincent

Hello list,
My project contain two elements, one application and one daemon (in fact a startupItem). Daemon perform privilege operation incoming from the application.
I'd like to know the best way to perform communication between application and daemon, I know I can use Notification with NSNotificationPostToAllSessions but it's not secure at all, every application can send a notification, NSConnection don't looks better...
Getting authorization is not a problem, the problem is to transmit it to the daemon.
If someone have an idea or a sample code
Hi Vincent,
Have you considered using either NSNotifications or NSConnection / Distributed Objects, but encrypt the data?
If both the app and the daemon know the private key, they can both use Blowfish (see <openssl/blowfish.h>) to encrypt / decrypt the data between them.
