How about having a "wrap" method that just sets up everything for you? That
avoids having the callers in a bunch of places call both `wrapForEncryption`
and `wrapForCompression` and have to worry about doing it in the right order.
I'd prefer if the existing `wrapFor...` methods became private or went
away, but if they make testing easier, then you can keep them.
