.\" Hey, EMACS: -*- nroff -*- .TH cryptcat 1 "August 9, 2001" "Debian GNU/Linux" "Cryptcat" .SH NAME cryptcat \- twofish encryption enabled version of .B nc(1) .SH SYNOPSIS .B cryptcat .RI "-k \fIsecret\fP [-options] hostname port[s] [ports]" .br .B cryptcat .RI "-k \fIsecret\fP -l -p port [-options] [hostname] [port]" .SH DESCRIPTION This manual page documents briefly the \fBcryptcat\fP 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 \fBcryptcat\fP and not the features that are described at length in the manpage for \fBnc(1)\fP. .br If you do not know \fBnc\fP then the chances are you won't have much use for this manpage. .PP \fBcryptcat\fP can act as a \fBtcp\fP or \fBudp\fP client or server - connecting to or listening on a socket, while otherwise working as the standard Unix command \fBcat(1)\fP. .PP \fBcryptcat\fP takes a password as a salt to encrypt the data being sent over the connection. Without a specified password \fBcryptcat\fP will default to the hardcoded password ``\fImetallica\fP''. Needless to say, failure to specify a different password makes the connection as good as unencrypted. .PP .SH OPTIONS This programs \fIdoes not\fP 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. .TP .B \-h .br Show summary of options. .TP .B \-k \fIsecret password\fP .br Change the shared secret password to be used to establish a connection. .SH BUGS This version of \fBcryptcat\fP does not support the \fB-e\fP \fIcommand\fP command line option available in some versions of \fBnc\fP. .SH SEE ALSO .BR nc(1), .BR cat(1). .br /usr/share/doc/cryptcat/README.gz .br /usr/share/doc/cryptcat/README.cryptcat .br /usr/share/doc/cryptcat/README.Debian .SH AUTHOR The original \fBnetcat\fP was written by \fBhobbit@avian.org\fP. \fBcryptcat\fP is the work of \fBfarm9 \fP with the help of Dan F, Jeff Nathan, Matt W, Frank Knobbe, Dragos, Bill Weiss, Jimmy. This manual page was written by Lars Bahner for Debian.
