Open document / Change security
A PDF file can have both an Open document password and a Change
security
password. When both passwords are applied, the document can
be opened using either one.
NOTE: When adding passwords the Open document and Change security passwords are not allowed to
be the same.
When the correct Open document password is provided, the document
is opened and decrypted. However, use of the document is limited by
whatever restrictions have been specified in the Security options and
Changes allowed panels.
The Change security password allows the recipient of the PDF file to
open the PDF and modify the security settings. When a file is opened
with a Change security password, unrestricted access to the document
is allowed. In effect, the security restrictions are temporarily disabled. If
you wish to limit access to your file, you should apply a Change security
password, otherwise anyone who opens the file is able to remove the
restrictions.
It is important to note that the PDF viewing application does not prompt
for a password if no Open document password is entered when creating
a secured PDF.
This means that when only a Change security password is used, the
document is opened without the user having to provide a password, and
use of the file is limited by whatever security restrictions have been
imposed.
With Encrypt PDF files selected, you can choose various options to
define the level of user actions allowed.
The Security options panel contains the following options:
Allow copying of text and graphics
When selected, the PDF user is able to copy and paste text and graphics
from the file.
Allow content access for accessibility
When selected, the PDF content is made available to assistive
technology such as screen readers even when the Allow copying of text
and graphics option is set to prevent copying content from the
document.
The Changes allowed panel lets you to define the level of changes you allow users to
make on the PDF document.
No options selected
With no options selected users are unable to do anything to the PDF
document, including filling in signature and form fields.
