Security page of PDF Options dialog box
PDF export includes options to encrypt the PDF (so it cannot be opened without a
password) and apply some digital rights management (DRM) features.
• With an open password set, the PDF can only be opened with the password.
Once opened, there are no restrictions on what the user can do with the
document (for example, print, copy, or change it).
• With a permissions password set, the PDF can be opened by anyone, but its
permissions can be restricted. See Figure 174.
• With both the open password and permission password set, the PDF can only
be opened with the correct password, and its permissions can be restricted.
Note
Permissions settings are effective only if the user’s PDF viewer respects
the settings.
Figure 175 shows the pop-up dialog box displayed when you click the Set open
password button on the Security page of the PDF Options dialog box.
After you set a password for permissions, the other choices on the Security page
(shown in Figure 174) become available. These selections should be self-explanatory.
