# CipherBox 🔒
CipherBox is a secure file encryption system that uses RSA and AES hybrid encryption to protect your files. Built with Python and Streamlit, it provides a user-friendly interface for file encryption and decryption while maintaining high security standards.
## 🌐 Live Demo
[](https://cipherbox.streamlit.app/)
## Features
### 🛡️ Security
- Hybrid encryption (RSA + AES) for optimal security and performance
- Unique encryption keys for each user
- Secure password hashing with salt
- Protected private keys
- Session-based authentication
### 📁 File Management
- Support for all file types
- File size limit: 10MB (configurable)
- Encrypted file tracking
- Secure file storage
- Multi-user support
### 🎯 Key Features
- User registration and authentication
- File encryption with personal keys
- File decryption for authorized users
- File history tracking
- Data clearing option
## Installation
### Prerequisites
```bash
- Python 3.8 or higher
- pip (Python package manager)
```
### Setup
1. Clone the repository:
```bash
git clone https://github.com/clueNA/cipherbox.git
cd cipherbox
```
2. Install required packages:
```bash
pip install -r requirements.txt
```
3. Initialize the database:
```bash
python create_database.py
```
4. Run the application:
```bash
streamlit run app.py
```
## Usage
### 👤 User Management
1. **Registration**
- Click the "Register" tab
- Enter username and password
- System generates encryption keys automatically
2. **Login**
- Use the "Login" tab
- Enter credentials
- Access your encrypted files
### 🔒 File Encryption
1. Select "Encrypt File" tab
2. Upload file (up to 100MB)
3. Click "Encrypt"
4. Download encrypted file (*.encrypted)
### 🔓 File Decryption
1. Select "Decrypt File" tab
2. Upload encrypted file (*.encrypted)
3. Click "Decrypt"
4. Download original file
### 📋 File Management
- View all encrypted files in "File List" tab
- Track encryption dates
- Manage file access
## Technical Details
### Security Implementation
```python
# Encryption Process
- RSA 2048-bit key pair generation
- AES-256 for file encryption
- PBKDF2 for password hashing
- Secure random salt generation
```
### Database Structure
- Users Table
- Username
- Password hash
- Public/Private keys
- Salt
- FileKeys Table
- Filename
- File hash
- Encrypted key
- Owner reference
## File Support
### Supported File Types
- Documents (.pdf, .doc, .txt, etc.)
- Images (.jpg, .png, .gif, etc.)
- Media files (.mp3, .mp4, etc.)
- Archives (.zip, .rar, etc.)
- Any other file type
### Size Limitations
- Default: 100MB
- Configurable in config.py
## Security Considerations
### Best Practices
- Keep encrypted files backed up
- Store passwords securely
- Don't share private keys
- Log out after usage
- Regular password updates
### Data Protection
- Files encrypted with personal keys
- Only file owner can decrypt
- Secure key storage
- Protected user sessions
## Troubleshooting
### Common Issues
1. **Registration Fails**
- Check username availability
- Ensure password meets requirements
2. **Encryption Fails**
- Verify file size limits
- Check file permissions
3. **Decryption Fails**
- Confirm file ownership
- Verify correct user login
- Check file integrity
