Loading Encrypted Files Using the Document Library

Some document file types, such as PDF, support optional encryption and require being decrypted with a password before they can be used. PDF is an example of such documents.

When you use the LoadFromUri or LoadFromCache methods to load these documents, a LEADDocument object is created and returned as usual. It will, however, be encrypted and unusable until the correct password is applied to decrypt it. Unusable means only the information properties of the document are available (such as its DocumentId and MimeType), but the Pages collection will be empty and you cannot interact with the document by getting any more information from it.

There are two ways to pass the password phrase used to decrypt this document:
