Cyphers

Let's build some Cyphers in C#

What is a Cipher?

An algorithm for performing encryption or decryption. It is one of the many facinating areas of study in classical cryptography. https://en.wikipedia.org/wiki/Cipher for more information!

Cipher.CLI

This is a console application build with System.CommandLine that allows to use the implemented ciphers.

To list the available ciphers:

$cyphers

To encode and decode morse code:

$cyphers morse-code -e hello
.... . .-.. .-.. ---

$cyphers morse-code -d ".... . .-.. .-.. ---"
hello

Some command may require extra options. Use them as follows:

$cyphers keyword
You must specify either the 'decode' or 'encode' option.
Option '-k' is required.

keyword
  Keyword sipher.

Usage:
  cyphers [options] keyword

Options:
  -d, --decode <decode>
  -e, --encode <encode>
  -k, --keyword <keyword> (REQUIRED)  Keyword.
  -?, -h, --help                      Show help and usage information

$cyphers keyword -k c -e abc
cab

$cyphers keyword -k c -d cab
abc
