Hi Everybody,

Does anybody know whether it is possible to encrypt AUTOMATICALLY in PHP
(at the server side) an Adobe PDF document (also stored at the server side)
by using a public key coming from a certificat of the client that want to
retreive, decrypt (with his private key) and read the PDF document ?

I would like to distribute PDF document to certified clients for which they
could only read the document on their PC that owns the certificat
(public/private keys) that has been used to encrypt the document at the
server side and allow to decrypt it at the client side.

Many thanks in advance for you help

Steph
