The B<enc> program does not support authenticated encryption modes
like CCM and GCM, and will not support such modes in the future.
The B<enc> interface by necessity must begin streaming output (e.g.,
to standard output when B<-out> is not used before the authentication
to standard output when B<-out> is not used) before the authentication
tag could be validated, leading to the usage of B<enc> in pipelines
that begin processing untrusted data and are not capable of rolling
back upon authentication failure. The AEAD modes currently in common
