 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
 tag could be validated, leading to the usage of B<enc> in pipelines
 that begin processing untrusted data and are not capable of rolling
