You ought to be able to put bdes(1) in the pipeline, like:
tar czplf - / | bdes -k BigSeCreT >/dev/???
See the man page for bdes. I would imagine that any cipher that
reads from stdin and writes on stdout will fill the bill.
I'm guessing here, and the pipe is just a suggestion for a starting
point for experimentation. There may be issues with streaming speed
and/or blocking. Maybe adding a dd after the bdes could help that?
Just guessing...
It might be a useful and clever hack to add a switch to dump/restore
to incorporate encryption.
Note, in the example, BigSeCreT may appear in ps listings, etc. There
are ways around that.
