thanks for the info ... it was usefull but it didn't help me too much, because I have to do everything by hand.
Step 1: save OO document as .ps
Step 2: open in scribus and save copy as .sca (scribus format) file
Step 3: export as pdf with all encryption settings
as said beforem, it is pretty usefull to know that there is such a tool, but I am looking for something which can do this automaticaly ... scribus does not have any usefull command line options ...
I'll try to compile it myself, there are maybe some configure options for turning this on.
