This won't help you much on Centos 6, but I use Libreoffice 5.0.3.2 on Centos 7 and it works fine. I just checked and the "Digital Signatures" tab exists and appears to be active on the PDF Export menu option, though I've not actually tried to use it myself. Does Libreoffice 5 not work on Centos 6? I've never tried that, either. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
