You should really consider using Prawn instead of FPDF, even though it  
also does not support this feature.

I am still waiting for someone to create a prawn-crypt (or  
prawn-secure) extension, but so far all people do is ask for this  
feature rather than work on it. It’s not a need of mine.

If everything else fails, you could run pdftk over the pdf on disk.
