Encrypter-Decrypter

This Python-based tool allows you to encrypt and decrypt text files using a Caesar cipher method. It provides a simple interface for securing your text data by shifting characters based on a secret key.

Features

  • Text Encryption: Encrypts plain text files by shifting characters using a randomly generated key.
  • Text Decryption: Decrypts previously encrypted text files using the provided secret key.
  • Clipboard Integration: Optionally copies decrypted text directly to your clipboard for easy access.
  • Local File Management: Handles files within local directories, avoiding the need for absolute paths.

Prerequisites

  • Python 3.x: Ensure Python is installed on your system.

  • Required Libraries: Install the necessary Python libraries using the following command:

    pip install pyperclip

Setup

  1. Clone the Repository:

    git clone https://github.com/ArielBaron/encrypter-Decrypter.git
cd encrypter-Decrypter

  2. Directory Structure:

    The project uses the following local directories:

    • ./FileForDorE: Main directory containing files to be encrypted.
    • ./Encrypted Files: Directory where encrypted files are stored.
    • ./Decrypted Files: Directory where decrypted files are stored.

    Ensure these directories exist or create them as needed.

Usage

  1. Run the Script:

    python Encrypter.py

  2. Follow the Prompts:

    • Select Folder: Choose the folder containing the file you wish to process:

      • 0 for Main Directory (./FileForDorE)
      • 1 for Encrypted Directory (./Encrypted Files)

    • Enter File Name: Provide the name of the file to encrypt or decrypt.

    • Choose Mode:

      • 1 or E for Encryption
      • 2 or D for Decryption

    • Encryption:

      • A random key between 1 and 110,000 is generated.
      • The file is encrypted and saved in the ./Encrypted Files directory.
      • The encryption key is displayed; store it securely for decryption.

    • Decryption:

      • Enter the secret key used during encryption.
      • The file is decrypted and saved in the ./Decrypted Files directory.
      • Optionally, copy the decrypted text to your clipboard by responding with y when prompted.

Notes

  • File Paths: The script uses relative paths for file operations, ensuring compatibility across different systems.
  • Clipboard Functionality: The pyperclip library is used for clipboard operations. Ensure it is installed and functioning on your system.
  • Security: The Caesar cipher is a basic encryption method and may not provide strong security for sensitive data. Use with caution and consider more robust encryption methods for critical information.
