This manual page documents briefly the cryptcat command. This manual page was written for
the Debian GNU/Linux distribution because the original program does not have a manual
page. It only documents the features specific to cryptcat and not the features that are
described at length in the manpage for nc(1).
If you do not know nc then the chances are you won't have much use for this manpage.

cryptcat can act as a tcp or udp client or server - connecting to or listening on a
socket, while otherwise working as the standard Unix command cat(1).

cryptcat takes a password as a salt to encrypt the data being sent over the connection.
Without a specified password cryptcat will default to the hardcoded password
``metallica''. Needless to say, failure to specify a different password makes the
connection as good as unencrypted.


This programs does not follow the usual GNU command line syntax, with long options
starting with two dashes (`-'). A summary of the options specific to cryptcat is included

Show summary of options.

-k secret password
Change the shared secret password to be used to establish a connection.
