How to set PDF security

About PDF security

A PDF file may be encrypted for security, or digitally signed for authentication.

The standard security provided by Acrobat PDF consists of two different methods and two different passwords, "user password" and "owner password".

A PDF document may be protected by password to open ('user' password) and the document may also specify operations that should be restricted even when the document is decrypted: printing, copying text and graphics out of the document, modifying the document, or adding or modifying text notes and AcroForm fields (using 'owner' password).

PDF document security should not be used as primary way of securing sensitive data, all operations (except the document open password protection, if applicable) which are restricted by "owner" or "user" passwords can be easily cracked by third party applications.

Even without removing the password, most freeware or open source PDF readers will ignore the digital rights management "protections" and will allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection.

Swing PDF Converter provides basic PDF document security, this includes:

• User password

• Master password

• No printing

• No changing the document

• No content copying or extraction, disable accessibility

• No adding or changing comments and form fields

User password

Authenticated user rights:

• Decrypt PDF document

• Read PDF document

• Other rights are defined by master user.

Master password

Master user rights:

• Change user rights

• Decrypt PDF document

• Read PDF document

• Print PDF document

• Modify PDF document

• Extract data from PDF document

Setting PDF Security from Lotus Notes

PDF Security can be set from "PDF Settings" view in the PDF Converter database.

Setting PDF Security from LotusScript API

The following article article explains how to set Swing PDF Converter API in custom application:
