|

* Add several methods to query permissions controlled by the
|
||||
encryption dictionary. Note that qpdf does not enforce these
|
||||
permissions even though it allows the user to query them.
|
||||
|
||||
* The function QPDF::getUserPassword returned the user password
|
||||
with the required padding as specified by the PDF specification.
|
||||
This is seldom useful to users. This function has been replaced
