put a password into the file using the command line

Hello there
I can use pdfcreator.exe to create the file from the command line as follows, but again I want to put a password into the file using the command line.
If you could help with this situation, I would greatly appreciate it.

pdfcreator /printfile="c:\scan\3.tif "/outputfile="c:\scan\3.pdf"

Hi,

sorry this isn't possible, you will need to use the COM interface for this.

Best regards

Robin
