How to Remove Password from PDF Files with Google Chrome

Safeguard PDF Security does what it says — it provides a manageable, cost effective uncomplicated way to secure PDF documents, your investment. While PDF encryption is used to secure PDF documents so they can be securely sent to others, you may need to enforce other controls over the use of your documents to prevent authorized users using documents inappropriately.

For example, you may want to stop users copying text or printing PDFs. So PDF file security is delivered by of a combination of different features — encryption, controls digital rights management controls , etc. Underpinning the controls is the strength of the PDF encryption and the implementation method.

If it is weak or can easily be subverted then it adds no value. PDF Restrictions give you limited controls over what an authorized user can do with a document.

To encrypt a PDF you need to use a key. The most common method is using a password as the key. Public Key Technology is much more secure than password protection — the key is not exposed to the user so cannot be attacked.

In addition there are no passwords to manage or for users to forget. Licensing controls allow you to establish policies, watermarks, and restrictions that are unique to each user.

You can distribute a single document that has different license conditions depending on the user. For example:. The main reason however is that you need protection for your PDF documents beyond what encryption provides.

The most likely reason being is that you want to have some control of your PDF documents once they have been decrypted for example whether a recipient can copy text from your document.

This may be because the information is privileged for a certain group of people or you are selling information that you do not want to be distributed at your cost.

Unlock PDF

Well, at the basic level you could use a product like Adobe Acrobat. However, it is wise to bear in mind that there are tools freely available on the Internet that remove the copy controls you have applied literally within seconds. If you are serious about protecting your documents then you will probably want to download a PDF file security product that is not password based — read PDF password protection to see why — and uses US Government strength encryption.

Download PDF file security software that uses US Government strength encryption, digital rights management controls, and does not use either passwords or plug-ins to secure your PDF documents. PDF password protection has been the traditional way to impose PDF digital rights management controls on PDF document users, but it has a number of drawbacks.

The weaker the password the sooner it is broken. In Adobe Acrobat, a number of additional controls PDF permissions such as stopping printing, editing, and copying text, can be added when you secure a PDF file with a password. So reliance on some of the controls being provided may not be as wise at it seems — they are totally useless. However, plug-ins may and often do act in conflict with each other, and other plug-ins may be used to compromise the security of the PDF security plug-in.

Also, the Adobe PDF Reader was not designed to operate in a secure manner, and it is not possible, as a plug-in, to control what the application can do, so any ability to compromise the application will also compromise the security.

PDF file security is achieved when the different components work together correctly. So if some of the controls are implemented by one supplier and others by another you need to make sure that the combinations work together. We supply and control the environment so that no vulnerabilities can be introduced.
