Hi,

When I run the "pdfinfo" command on some PDF files created with Acrobat 
software I get the following information:

...
Encrypted:    yes (print:yes copy:no change:no addNotes:no)
Linearized:   yes

If I run the same command on PDF files that I create with "ps2pdf" I get 
this info:

...
Encrypted:    no
Linearized:   no

I'm not sure what linearizing does to PDFs, but I think it would be 
pretty cool to encrypt PDF files so they can only be printed. Is there 
any command I can include in my .lyx file so the result of exporting to 
PDF is an encrypted file?

TIA,
Roberto
