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 a client that wants to
retreive, decrypt (with his private key) and read the PDF document ?

I would like to distribute PDF documents 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 (the public key) to encrypt the
document at the
server side and to allow (with the private key) to decrypt it at the client
side .

Many thanks in advance for you help

Steph
