🔐 Message Encoder & Decoder

A simple yet effective Python tool that encodes and decodes text messages using character manipulation and random letter injection for basic encryption.

• 🔒 Encode messages with a custom algorithm
• 🔓 Decode previously encoded messages
• 🎨 Colorful terminal output for better readability
• 🔄 Option to continue encoding/decoding multiple messages
• 🛡️ Basic text scrambling for casual privacy

• Python 3.x
• termcolor library

# Clone the repository
git clone https://github.com/Naeem-360/message_encode_decode.git

# Navigate to the project directory
cd message_encode_decode

# Install required packages
pip install termcolor

Run the script using Python:

python encode_decode.py

1. Takes each word in your message
2. For words with 3 or more characters:
   • Swaps the first and last character
   • Adds 3 random letters at the beginning
   • Adds 3 random letters at the end
3. For words with fewer than 3 characters:
   • Simply reverses the word

1. Takes each encoded word
2. For words with random letters added:
   • Removes the first 3 random characters
   • Removes the last 3 random characters
   • Swaps the first and last character back to original position
3. For short words:
   • Reverses them back to original

The application features:

• Clear menu options for encoding or decoding
• Color-coded results (encoded messages in red, decoded messages in yellow)
• Divider lines for improved readability
• Friendly welcome and exit messages with emoji

Original message:

Hello World

Encoded message (random letters will vary):

abc oellHxyz def orlWdghi

Decoded message:

Hello World

• 📱 Send messages with basic privacy
• 🎮 Create simple puzzles or games
• 🎓 Educational tool for understanding basic text manipulation
• 🔍 Introduce beginners to the concept of encryption

This is a simple encoding algorithm for fun and is not suitable for securing sensitive information. It provides only very basic obfuscation, not true cryptographic security.
