# Introduction

Shoe lace cipher:

**Objective**  
- Using the shoe lacing pattern to create a symmetric cipher, using lacing techniques, digital encoding, and alphabets.

**Encoding techniques**  
This repo allows you to cipher texts using an algorithm derived from traditional shoe lacing methods.  
For the purpose of simplicity, we’d be focusing on three lacing patterns respectively:

- Criss cross

- Army

- Straight european

Lacing Technique Rules:
All letters are uppercase ASCII letters
Letters are placed in form of rows mapped side by side to their corresponding odds and evens index A-B,C-D… Y-Z forming a 13th row matrix.
The letters on the left sides are considered odds (letter % 2 != 0) while letters on the right are considered evens (letter % 2 ==0)

# Usage
1. Clone the repo with: `git clone https://github.com/NBGtega/shoelace-cipher.git`
2. cd to the repo name: `cd shoelace-cipher`
3. Example for criss-cross encryption:
   ```bash
   python3 main.py -m [your msg here] -e cc
   ```

Use help option for details: `python3 main.py -h`
