Text Encryption and Decryption with Image-Based Key

Overview

This Python application provides functionalities for encrypting and decrypting text using a symmetric encryption scheme. The key for the encryption is derived from an image file chosen by the user. The application uses the cryptography library for encryption and decryption, and the Pillow library for image processing.

Features

• Encrypt Text: Enter text and encrypt it using a key derived from an image.
• Decrypt Text: Enter encrypted text and decrypt it using the same image-derived key.
• Copy to Clipboard: Copy the encrypted text to the clipboard for easy sharing.
• Paste from Clipboard: Paste text from the clipboard to decrypt.
• Upload Image: Upload an image file to generate a fixed hash and encryption key from it.

Requirements

• Python 3.x
• cryptography library
• Pillow library
• numpy library

You can install the required libraries using pip:

pip install cryptography Pillow numpy
