Hi,

We distribute data updates to our dotnet client apps in form of Access
files. We want to protect the content of these files from unauthorized
readers but we cannot figure how to do this...

Our thoughts are:

1) Access database passwords can easily be broken and are therefore
not enough.
2) The client app is C# and can therefore be reverse-compiled to
reveal the tricks we use to camouflage the file content.
3) If we encrypt the file the client app must have the key to decrypt
the file. But it can be revealed due to 2).
4) We can "obfuscate" our code but all passwords and keys will still
be present and somewhat visible.

We may be missing some important points and/or technologies here - so
please advise on what approach to take here!

Thanks in advance!
