## 🔐 **Encryption Methods**

```
🔐 ENCRYPTION METHODS USED
═══════════════════════════════════════════════════

CipherForge uses secure encryption methods:

1. KEY DERIVATION:
   • PBKDF2 with SHA-256
   • 100,000 iterations for brute force resistance
   • Unique 256-bit salt per file

2. ENCRYPTION ALGORITHM:
   • XOR-based stream cipher
   • 256-bit encryption keys
   • Chunk-by-chunk processing

3. INTEGRITY PROTECTION:
   • SHA-256 checksums
   • File size verification
   • Password verification

4. SECURITY FEATURES:
   • No password storage in files
   • No backdoors or recovery methods
   • Memory-safe operations

⚠️ IMPORTANT:
   • Without correct password, decryption is mathematically impossible
   • Each file has unique encryption parameters
   • Lost password = permanently encrypted data
```

## 🛠️ **Technical Details**

### **File Format**
```
[3 bytes]  Magic: "CF!"
[32 bytes] Salt
[8 bytes]  Original file size
[...]      Encrypted data
[32 bytes] SHA-256 checksum
```

### **Supported File Types**
- **Documents**: PDF, DOCX, XLSX, PPTX, TXT
- **Images**: JPG, PNG, GIF, BMP, SVG, TIFF
- **Videos**: MP4, AVI, MKV, MOV, WMV
- **Audio**: MP3, WAV, FLAC, AAC
- **Archives**: ZIP, RAR, 7Z, TAR
- **Executables**: EXE, MSI, APP, APK
- **Any binary file**

### **System Requirements**
- **Python 3.8+**
- **Operating System**: Windows, macOS, Linux
- **Storage**: Enough space for encrypted copies
- **Permissions**: Read/write access to target folders

## ⚠️ **Important Notes**

### **Security Warnings**
1. **NO PASSWORD RECOVERY** - Lost password = permanently encrypted data
2. **NO BACKDOORS** - Developer cannot help recover files
3. **TEST FIRST** - Always test with non-critical files
4. **BACKUP IMPORTANT FILES** - Keep copies before encryption

### **Best Practices**
1. **Save passwords** in a secure password manager
2. **Test encryption/decryption** with sample files first
3. **Keep original files** until confirming decryption works
4. **Use strong passwords** (minimum 12 characters)

## ❓ **Troubleshooting**

### **Common Issues & Solutions**

| Issue | Solution |
|-------|----------|
| "File not found" error | Use full paths or drag & drop |
| Permission errors | Run as administrator (Windows) or use sudo (Linux/macOS) |
| Decryption fails | Check password accuracy, ensure file wasn't modified |
| Large file slow processing | Normal - uses chunk-based encryption |
| Clipboard not working | Install pyperclip: `pip install pyperclip` |

### **Error Messages**
- **"ERROR: Wrong password or file corrupted"** → Check password, ensure file wasn't modified
- **"Not a CipherForge encrypted file"** → File wasn't encrypted with this tool
- **"File header corrupted"** → File was modified or damaged
- **"Size mismatch"** → Encryption/decryption process interrupted

## 🔧 **Advanced Usage**

### **Command Line Arguments (Future Feature)**
```bash
# Encrypt file
python cipherforge.py -e input.pdf -p "MyPassword123!"

# Decrypt file  
python cipherforge.py -d input.pdf.encrypted -p "MyPassword123!"

# Batch encrypt folder
python cipherforge.py -e folder/ -p "MyPassword123!"
```

### **Custom Configuration**
Edit these constants in the script:
```python
# Change chunk size for performance
self.chunk_size = 65536  # 64KB chunks

# Change key derivation iterations
iterations = 100000  # PBKDF2 iterations

# Change output extension
output_file = file_path + '.encrypted'  # Default extension
```
