Set password

Docotic.Pdf Library Help > Samples > Security > Set password

This sample shows how to protect your PDF document with a password.

There are two passwords types: a "user" and an "owner" password. PdfDocument.OwnerPassword property is for an "owner" password and PdfDocument.UserPassword property is for a "user" password.

Opening a PDF document with an "owner" password allows a reader of your document to do everything with opened document. Opening a PDF document with a "user" password allows a reader of your document to only perform operation allowed by user access permissions.
