File Encryption and Decryption Web Application

This web application provides a simple interface for encrypting and decrypting text using AES encryption. It consists of a Go backend server for handling encryption and decryption operations, and a frontend HTML/CSS/JavaScript interface for user interaction.

Features

  • Encryption: Encrypts input text using AES encryption and displays the encrypted result as a hex-encoded string.
  • Decryption: Decrypts hex-encoded encrypted text back to its original plaintext form.
  • User Interface: Clean and intuitive interface designed using HTML, CSS, and JavaScript for seamless user interaction.

Setup and Usage

Prerequisites

Installation and Running the Application

  1. Clone the Repository:

    git clone https://github.com/yourusername/Encryption-Decryption-GO.git
cd Encryption-Decryption-GO

  2. Start the Go Server:

    go run main.go

    This will start the Go server on http://localhost:8080.

  3. Access the Web Application:

    • Open your web browser and go to http://localhost:8080.
    • You should see the main page of the application with a textarea for input, radio buttons for selecting encryption or decryption, and a submit button.

Usage

  • Encrypting Data:

    1. Enter text into the textarea.
    2. Select the "Encrypt" radio button.
    3. Click the "Submit" button.
    4. The encrypted data will be displayed in the output area.

  • Decrypting Data:

    1. Paste the hex-encoded encrypted data into the textarea.
    2. Select the "Decrypt" radio button.
    3. Click the "Submit" button.
    4. The decrypted plaintext will be displayed in the output area.

Development and Customization

  • Adding Styles:

    • Modify style.css to customize the appearance of the web application.

  • Enhancing Functionality:

    • Expand functionality by modifying main.go to handle additional features or improve error handling and security measures.

Security Considerations

  • This application demonstrates basic AES encryption/decryption techniques and is suitable for learning purposes.
  • For production use, implement HTTPS to secure data transmission between the client and server.
  • Ensure proper handling and storage of encryption keys to maintain data security.
