Adam thanks for your reply.

i know that security is much decreased since the
phisical file is going to be copied into the
clients' machines.

i also know that anyone with the time and interest in
can make a reverse ingeniering into the APP and try
to find the key for decryptation.

it is a balance of cost/benefit

we think that encrypting (ofuscating) the data is
enought. the problem is how to do it with FB.

any idea ?

thanks in advance,
