GCIPHER

NAME

SYNOPSIS

gcipher [CIPHEROPTIONS]... [INPUT] [OUTPUT]

gcipher [CIPHEROPTIONS]... -p PROXIEDHOST PROXIEDPORT LISTENINGPORT

CIPHEROPTIONS:

(-c | -C) CIPHER [-k KEY]

"-" may be used for either INPUT or OUTPUT to represent STDIN or STDOUT respectively.  

EXAMPLES

Show the GUI:

gcipher

Encrypt a file using the Gie cipher:

gcipher -c Gie inputfile outputfile

Decrypt STDIN and output to STDOUT using Rot13:

gcipher -C Rot -k 13

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 Vigenere with key linux:

gcipher -c Vigenere -k linux -p gnu.org 1028 1027

DESCRIPTION

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.

-c CIPHER

encrypt using the given cipher

-C CIPHER

decrypt using the given cipher

-k KEY

set the key for the previous cipher

-p PROXIEDHOST PROXIEDPORT LISTENINGPORT

act as a network proxy

CIPHERS

Gie

a simple cipher doable by hand; no key is required

Ceasar

Julius Ceasar's code; no key is required

Rot

linear rotation; the amount of the rotation is given by the key which must be a number in the range [0, 25]

Vigenere

a version of ROT that uses a private key; the key must be made of lower-case letters
