Encode/decode a text message using various ciphers

Cipher Suite

The output of an exercise in learning how various ciphers work; an application that has the ability to encode/decode a text message using various ciphers.

Current ciphers supported:

• Caesar cipher
• Vigenère cipher

Getting Started

First build the app:

make

An executable named cipher will be created in the bin/ directory.

From there, use the help command to see the list of options available.

cipher --help

Tests

Build the tests with

make test

An executable named run-tests will be created in the bin/ directory.

Run the tests by executing run-tests

run-tests

Static Analysis

Static analysis can be run on the codebase using Cppcheck and/or Infer.

I've made Makefile rules to run these tools with some suitable arguments.

make check-cppcheck

make check-infer

To-Do

• Add autokey mode to Vigenère cipher
• Add Vigenère cipher variation: Variant Beaufort
• Add ability to read/write input/output files
• Start finding ways to create a tool to help decipher Vigenère ciphers
