I don't understand exactly the explications in PDF Reference.
To protect my PDF file, I must add an object like :
6 0 Object << /Filter /standard /R2 /O ??? /U ??? /P ??? /V1 /Lenght ??? >> endobject
and I must add in the trailer :
/Encrypt 6 0 R
If it's ok, what sort of data do I write in place of ???
