compression AND encryption

[stephen barncard]

Hello again, list friends.

I know milage varies on file compression, especially that MP3s are basically
already compressed and gain no advantage.
Still I have a project where the client is asking for encryption AND
compression.

I've been pondering this. At first, I didn't think this would make any
difference which came first. However, all kinds of files could be in the
Que., and the client wants 'em all pushed through the process.

So
on encode - (reverse order on decode)

1 compression, then encryption  <--my guess
2 encrypting, then compression
3 no difference or downside??


thanks
