RedHat Setting Password For PDF File--Linux

Hi,

I am in need of help. My requirements are :
1) To convert the existing files (irrespective of their format) in a directory to PDF format
2) To make the converted files password protected.

I did the attempt to do the same. Though the existing files (irrespective of their format) are getting converted to pdf, but when I take the the to local desktop, it is not opening as its pops "format not supported".
I did as " mv $i* $i.pdf " (variable i which holds the existing file name alone).
I have no idea how to make it password protected.

Please help me asap.
