Project Requirement:



The requirements can be achieved using either of the two methods stated below:



1. A code preferably in C# / ASP .net to automatically encrypt a PDF file. After a PDF file is encrypted users should not be able to save/print a copy of that file. Also there needs to be an option of days till the content expires (if possible) the system will fetch days to expire value from the database and add that encryption to the PDF file so that the users will not be able to view that document after a certain number of days.



2. A code which will remove right click option in a pdf file and also to disable shortcuts like CRTL + P (to print) and all.



We would prefer to see example of where you have used this type of module (if feasible). We would like to know on what your approach would be and how you would achieve the above stated goal with a detailed plan. We will review it and reply back.<br clear="all" />
