Adobe® PDF files can be created with or without security. Creating a secure PDF file allows you to restrict what can be done with the contents of the file. For instance, you can allow people to read and print the file but not be able to copy any of the text or images out of the file.

Supported security options consist of two different levels of encryption, the ability to control what the viewer can do with PDF file, and two levels of password protection.

Secure PDF files will take longer to create than non-secured files.

Encryption Level

There are two encryption options available. The encryption option chosen determines what version of Acrobat is needed to open and view the file.

40-bit Encryption:

The PDF file can be opened in Acrobat 3.0 and later versions.

128-bit Encryption:

The PDF file can be opened in Acrobat 5.0 and later versions.

Allow Users to

Depending on what you want viewers to be able to do with the PDF file you create, different permissions can be set to restrict what can and cannot be done.

Copy text and graphics:

Enable this check box to allow text and images in the file to be selectable and allow copying to the clipboard for use in other documents.

Print the document:

Enable this check box to allow the file to be printed. When this is not checked the document can only be viewed on screen.

Change the document:

Enable this check box to allow pages in the file to be inserted, removed and modified. This also allows document signing as well as adding or editing form fields.

Add or change comments and form fields:

Allows only form fields and comments to added, edited or removed; pages cannot be added or removed.

Password Settings

There are two levels of password protection that can be set – one for opening the PDF file (also known as the document open password), and one for making changes or modifying the file (also called the permissions password).

User password required to open document:

Enable this check box to require anyone opening this file to type in the password you specify.

Password - type in the password you want to use to open the file.

Confirm - type the same password in again to confirm.

Owner password required to change document:

Enable this check box to require anyone making changes to this file to type in the password you specify. When set, this password is required to change the security settings or to modify permissions on the document, such as whether content copying or form field editing is allowed.

Password - type in the password you want to use to change the file.

Confirm - type the same password in again to confirm.

If both the user password and the owner password are set, entering either password for the open document password prompt will open the PDF file.
