Thanks, presumably it uses crypt(3) (me fails to check...)

As I was browsing around the SUS, I noticed cpio and tar are
marked LEGACY. Presumably pax (which I've not tried) provides all
the functionality; but I see it uses rsh (rmt(8)) by default for
remote connections.  Any plans to change that to ssh? or stick to
using pipe to ssh?
