.SH NAME
gcipher \- a simple encryption tool
.SH SYNOPSIS
.B gcipher
.PP
\fBgcipher\fR [\fICIPHEROPTIONS\fR]... [\fIINPUT\fR] [\fIOUTPUT\fR]
.PP
\fBgcipher\fR [\fICIPHEROPTIONS\fR]... \fB-p 
\fIPROXIEDHOST PROXIEDPORT LISTENINGPORT\fR
.TP
\fICIPHEROPTIONS\fR: 
(\fB-c\fR | \fB-C\fR) \fICIPHER\fR [\fB-k\fR \fIKEY\fR]
.PP
"-" may be used for either \fIINPUT\fR or \fIOUTPUT\fR to represent 
\fISTDIN\fR or \fISTDOUT\fR respectively.
.SH EXAMPLES
.TP
Show the GUI:
.B gcipher
.TP
Encrypt a file using the \fIGie\fR cipher:
\fBgcipher -c Gie inputfile outputfile\fR
.TP
Decrypt STDIN and output to STDOUT using Rot13:
\fBgcipher -C Rot -k 13\fR
.TP
Listen on port 1027 and act as a proxy for port 1028 on gnu.org.  Decrypt the data coming from gnu.org and encrypt data going to gnu.org using \fIVigenere\fR with key \fIlinux\fR:
\fBgcipher -c Vigenere -k linux -p gnu.org 1028 1027\fR
.SH DESCRIPTION
.PP
This is a simple encryption tool to work with home-grown encryption algorithms.
It can run as either a GUI, a command-line application, or a network proxy.
.TP
\fB\-c \fICIPHER\fR
encrypt using the given cipher
.TP
\fB\-C \fICIPHER\fR
decrypt using the given cipher
.TP
\fB\-k \fIKEY\fR
set the key for the previous cipher
.TP
\fB\-p \fIPROXIEDHOST PROXIEDPORT LISTENINGPORT\fR
act as a network proxy
.SH CIPHERS
.TP
\fBGie\fR
a simple cipher doable by hand; no key is required
.TP
\fBCeasar\fR
Julius Ceasar's code; no key is required
.TP
\fBRot\fR
linear rotation; the amount of the rotation is given by the key which must be a
number in the range [0, 25]
.TP
\fBVigenere\fR
a version of ROT that uses a private key; the key must be made of lower-case
letters
