Project Objective:

To create a user-friendly web interface using Bootstrap that allows users to encrypt and decrypt files securely. The goal is to help protect sensitive data by converting files into unreadable formats and restoring them only with the correct key or password.

???? Core Features:

1. File Upload Interface:

• A clean and responsive Bootstrap-based UI
• Users can:
• Upload a file (PDF, TXT, DOC, etc.)
• Choose to encrypt or decrypt
• Enter a password or key

2. Encryption & Decryption:

• Once the file is uploaded:
• Encryption: Converts the file content into an unreadable format using a cryptographic algorithm
• Decryption: Restores the original content using the correct key
• Common encryption algorithms used:
• AES (Advanced Encryption Standard)
• RSA (optional for public/private key encryption)

3. Download Option:

• After processing, the encrypted or decrypted file is available for download

????️ Technology Stack:

1. Frontend (User Interface):
2. HTML + Bootstrap – for responsive and modern UI
3. Forms and buttons styled using Bootstrap classes
4. Optional: Use JavaScript for real-time feedback (e.g., file selected, loading status)

Backend (Logic):

• Typically handled using:
• Python (Flask/Django) or PHP – for encryption/decryption logic
• Cryptography libraries (e.g., pycryptodome in Python or openssl in PHP)

✅ Project Outcome:

• A sleek, mobile-friendly web app that lets users:
• Securely encrypt files before sharing or storage
• Decrypt files when needed using the correct key
• Demonstrates:
• Bootstrap for front-end design
• Basic cybersecurity concepts
• Frontend-backend integration
