Encrypted PDF support (PDF with password)

Currently one can only upload and interfere with decrypted PDF / no password.

Aim: It would be great if it was possible to upload and use encrypted PDF / password. One would by choice type in once the password after uploading it or type it in everytime by oneself.

Need: In times of more and more digital uprise merchants do sell books and knowledge as PDF. To protect themselves they use password / encryptions. As a customer I could decrypt it with some effort, but this would infringe my contract with the company.

A lot passwords are engined by the “FileOpen-Plugin" for PDF for Mac and Windows-Users
