cryptcat

A lightweight version netcat extended with twofish encryption

NAME

cryptcat - twofish encryption enabled version of nc(1)

SYNOPSIS

cryptcat -k secret [-options] hostname port[s] [ports]
cryptcat -k secret -l -p port [-options] [hostname] [port]

DESCRIPTION

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.

OPTIONS

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 below.
-h Show summary of options.
-k secret password
Change the shared secret password to be used to establish a connection.

BUGS This version of cryptcat does not support the -e command command line option available in some versions of nc.
