Caesar Cipher CLI Toolkit for encryption, PDF, and folder protection

🔐 Caesar Cipher Toolkit

Caesar Cipher Toolkit is a free, open-source CLI framework for encoding and decoding files using the classic Caesar 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
• Caesar 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. Caesar Encode Text
2. Caesar Decode Text
3. Encrypt PDF
4. Decrypt PDF
5. Encrypt Folder (EncFS)
6. Mount Encrypted Folder
7. Exit

🧠 Caesar 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
