No. You wrote that this possibility is mentioned somewhere. Where?
in the pdf specs
Hmmm. I can find only (p. 92 1.6spec): "The absence of this entry (/Encrypt) from the trailer dictionary means that the document is not encrypted."
It seems to me now that rights without passwords relies with /Perms in catalog (p.117, 699) and signatures (p.684). Something like:
----------------------------- \pdfcompresslevel=0
\immediate\pdfobj
{<< /Type /Sig
/Filter % something from Adobe.PPKLite Entrust.PPKEF CICI.SignIt VeriSign.PPKVS
/Contents % signature
/ByteRange %?? UR3 in /Perms
/P -4
>>}
\edef\DocMDPobj{\the\pdflastobj\space 0 R }
\immediate\pdfobj
{<< /Type /Sig
/Filter % something from Adobe.PPKLite Entrust.PPKEF CICI.SignIt VeriSign.PPKVS
/Contents % signature
/ByteRange %?? UR3 in /Perms
/P -4
>>}
\edef\URRRobj{\the\pdflastobj\space 0 R }
\pdfcatalog{/Perms << /DocMDP \DocMDPobj /UR3 \URRRobj >> }
Hallo \end ------------------------------
Sorry for uncomplete code, but I have not studied the signatures yet.
And sorry for a bit out of ConTeXt topic. Hans, is it time to move to the pdftex list?
