This article presents how to determine if a PDF document is encrypted with password using Spire. This is a much bigger subject area than the simple storage and retrieval of application settings, and will occupy most of this chapter and all of the next one The objectmodel within a program holds the main data Typically, this data is the reason the program is there in the rst place Word-processed documents, spreadsheets, computer-aided drawings, photographs, and Visual Basic Program Code are all things that a user would consider to be the core data of their respective programs, and in an object-oriented world, would reside in the object-model of the program as it executed A user will rightly expect the programs to allow their object-model data to be stored off-line so that the object-models can be recreated during a subsequent run Some programs, such as word processors, spreadsheets, programming languages and drawing programs will need the ability to create any number of les so that the user can work on different documents at different times Other programs, such as address-book software, web browsers and games may only work with a single le or set of les, storing the latest state of the object model whenever they are shut down and retrieving it the next time they are run In either case, the ability to save to and retrieve from a le will be similar The signi cant difference between these types of program is in whether the users are given the option to create new les or not In a program that allows the user to create new les and store them by name, we think of the program as being a producer of documents remove password from pdf using c# iText - PdfReader not opened with owner password
