Protect your PDF
I often send document to customers document created from OpenOffice in PDF format. To protect your hardwork add a PDF password. PDFTK from Stewart Sid is excellent and has many functions as detailed on the website but I use it for protecting PDF documents. Windows and Linux versions available. Windows Install. Download PDFTK and copy pdftk.exe into c:/windows/system32 To password protect and allow printing (unable to change or copy/paste document) pdftk inputfile.pdf output output.pdf owner_pw password allow printing
