How to protect password protected PDF file from being cracked

Cracked Pdf

It has been generally accepted by the legal industry that PDF provides a layer of protection against document modification due to the perception of fixed format, and many consider that PDF documents cannot be modified. This idea, unfortunately, is simply not true. This article provides some insights into the security issues with PDF and some helpful ways you can better protect your documents from unwanted modification.

The main issue Many firms are under the misconception that PDF documents cannot be modified. They package the document often a settlement agreement or other contractual agreement into PDF, send it out and then await the other side to request any changes. There is an expectation of a cordial exchange and that discussion will occur about any changes.

This assumption has worked well for the past ten or so years, where low experience with technology has been the norm for lawyers entering the field. Such basic knowledge, however, can come with some pitfalls based on erroneous assumptions, and lawyers can be caught unaware if they find their PDF documents returned to them with changes. PDF security in 30 seconds or less [Note: The information here is a very basic overview, as security is more complicated than space in this article allows.

The recommendations below are not a detailed review of PDF security, nor do they provide a complete list of PDF security features and their possible implementations. Digitally signed authentication will not be dealt with in this article as its primary focus is to protect against third party access.

While it can provide protection against modification, it requires a number of complicated steps as well as recognised Certificate Authority CA certificate signing, which has seen less adoption due to cost and greater technical expertise from both senders and receivers. For now, I will deal with some simple, inexpensive steps to assist with greater protection against modification.

First suggestion The first of these is the built-in password level protection provided within PDF. This free authentication methodology is relatively easy to execute and requires little-to-no technical expertise. The password level of security allows for the protection against unauthorised opening of the document, as well as restrictions as to the change permissions allowed for editing, printing and access.

The advantage of this level of security is that you can stipulate what you will allow, and you do not have to provide the other side with the password to simply read the document.

Let us take a simple walk through password implementation. First open a PDF document any document will do, provided it is not already password protected. In Figure 1 below, you can set the changes you wish to allow for the reader. You will then be asked to retype your password and then save the document.

Protection is not executed until you save, so be sure to do so. Remember to note your password for the document, otherwise you or anyone to whom you provide the password will be unable to make changes. This is the same for Adobe Reader. The example above deals specifically with Adobe Writer and third party software may require different steps. Their original intention was to assist Mac users when they had forgotten their password and needed to edit a PDF, but they have since been used by people to remove passwords in order to read, edit and modify documents.

For these reasons, a PDF document in this form should not be considered secure and is only, at best, non-editable by a non-technical party. A better suggestion This leads on to the second and my preferred option for sending a document that you do not want edited. In my opinion, one of the best ways to secure a PDF is to save it as an image see Figure 2.

This option creates greater security against editing, as when you print to PDF you create an image of the document rather than ISO text, which is the normal PDF document standard. Furthermore, it requires a greater level of technical knowledge to execute the changes or extract and edit the image file and, despite it being an image, the image is saved within the PDF document, providing the same flexibility of PDF fixed layout, without the security issues of direct text manipulation.

If you want others to be able to fill out forms, then this option will not work as the image cannot be set to have form fields. I would accordingly recommend the password security method for forms. It must be stressed that a person who is familiar with PDF editing, Photoshop, or other image manipulation tools will still be able to edit these types of documents.

However, the level of technical expertise and time required to do so, in my opinion, results in your documents being better secured against editing. Conclusion PDF security is limited and while this article provides some tips to better protect documents against editing, there is no guarantee against this when dealing with people with technical knowledge of Photoshop or other PDF editors.

So, always be mindful of who your recipient is and the risk of PDF editing when choosing to send your documents by PDF. If you have any other document security tips that you think would help firms, I would love to hear from you and I will provide updates in future articles as to the outcome of my testing of any other proposed solutions — you can contact me at lloyd gallagherandco.
