+      <p>FOP supports encryption of PDF output, thanks to Patrick C. Lankswert.
+      This feature is commonly used to prevent unauthorized viewing, printing, editing, copying text
+      from the document and doing annotations. It is also possible to ask the user for a password in
+      order to view the contents. Note that there already exist third party applications which can
+      decrypt an encrypted PDF without effort and allow the aforementioned operations, therefore the
+      degree of protection is limited.  For further information about features and restrictions
+      regarding PDF encryption, look at the documentation coming with Adobe Acrobat or the technical
+      documentation on the Adobe web site.</p>
