# 🔐 DES Encryption Web App (Flask)
A simple web application built with **Python** and **Flask** that enables users to perform text encryption using the **Data Encryption Standard (DES)** algorithm. The app provides a user-friendly interface to input plaintext and an 8-character key, and displays the encrypted result in hexadecimal format.
## 🚀 Features
- Encrypt text using the DES algorithm (ECB mode)
- User-friendly web interface built with HTML and Flask
- Key validation to ensure exactly 8 characters
- Displays encrypted output in hexadecimal format
## 🛠 Technologies Used
- Python 3.10
- Flask
- PyCryptodome (for cryptographic operations)
