Hi All,

Can someone please tell me if the following scenario is doable with Adobe
Reader plug-in's:

- I provide encrypted pdf's (not Adobe encryption but custom one).
- When Reader opens the protected pdf, the plug-in starts, unprotects the
pdf (the whole document) and provides the Reader with the unprotected
version.
- The pdf is never saved on disk in cleartext


I started reading the plug-in SDK but there are so many new things for me so
I would appretiate if someone answers.

Which layer should I use for the decryption: AV, PD, cos...? Should I use
something similar as in UncompressPDF sample? I learned how to hook to
Reader events, just the decryption of the whole pdf document is unclear to
me.

Any help is welcomme!

Thanks a lot,
Sasha
