 connections.  Examples are all over.  [This post][DB] by Dustin Breese
 seems good.
 
+Also note that with the `crypt` USE flag, Gentoo will install netcat
+with an [AES][] patch by [Mixter][], which allows

+    $ nc -k <password> -l -p <port> <host>

+AES is a symmetric-key encryption standard, so you don't have to go
