An open-source C# library for reading/verifying PSN authentication tickets.
This library is mostly based off of Project Lighthouse's implementation. We've taken some creative liberties and shipped it as a package for use by other PS3 custom server developers.
Here's a list of projects using NPTicket for reference.
You can also look at the NPTicket.Test project in this repository for a basic overview.
