Ceasar Cipher Toolkit is a free, open-source CLI framework for encoding and decoding files using the classic Ceasar cipher. It also includes powerful tools to encrypt PDFs and folders — without compressing or modifying original file contents.

No command-line arguments required — just run and go. The interactive menu handles everything.

Features

  • Interactive menu-driven interface
  • Ceasar cipher encode/decode with header-based shift tracking
  • PDF file encryption and decryption with password
  • Folder encryption using encfs (no zipping or renaming)
  • Animated loading spinners for all actions
  • Colorized success/error messages with colorama

Example Use

python main.py

Then choose one of the options:

1. Ceasar Encode Text
2. Ceasar Decode Text
3. Encrypt PDF
4. Decrypt PDF
5. Encrypt Folder (EncFS)
6. Mount Encrypted Folder
7. Exit

Ceasar Cipher Usage

  • Encodes any text file with a shift you provide
  • Stores Shift:N at the top of the file for auto-decoding

Example

  • Input: document.txt
  • Output: document_enc.txt

Then decode → output: document_dec.txt

PDF Protection

  • Encrypts PDFs with a password using PyPDF2
  • Decrypts PDFs with the correct password

Example

  • Input: contract.pdf
  • Output: contract_enc.pdf
  • Then decrypt → contract_dec.pdf

Folder Encryption (EncFS)

  • Encrypts folders without changing contents
  • Does NOT zip, rename, or modify files
  • Uses encfs for true on-demand file encryption

Encrypt

  • Input: project/
  • Output: project_encrypted/

Decrypt

  • Input: project_encrypted/
  • Output: project_decrypted/ (automatically extracted)

Requirements

Python Modules

pip install PyPDF2 colorama

System Tools

sudo apt update
sudo apt install encfs

Installation

1. Simply install using the python pip package but first make sure you use Virtual Environment and source the activate:

python -v venv venv

# Bash / Zsh
source venv/bin/activate

# Fish shell
source venv/bin/activate.fish

# C shell (csh / tcsh)
source venv/bin/activate.csh

Install Ceasar-toolkit

pip install ceasar-toolkit

Then simply call ceasar in your commands.

2. Clone the project and run:

git clone https://github.com/parsabe/Ceasar-cipher-toolkit.git
cd Ceasar-cipher-toolkit
python main.py
