Implement configuration file for default settings and preferences

[BhoomiAgrawal12]

Description

Allow users to configure default behaviors through a configuration file rather than requiring command-line arguments or menu selections each time.

Use Cases

• IT departments wiping multiple devices with same settings
• Default operator ID for certificate generation
• Preferred wipe algorithm
• Automatic verification enable/disable
• Certificate storage location
• Log verbosity level

Proposed Solution

1. Configuration File Format

   • Use INI or YAML format
   • Location: /etc/securewipe/config or ~/.securewipe/config
   • Example:

     [general]
     operator_id = IT-DEPT-001
     certificate_path = /media/usb/certificates/
     
     [wipe]
     default_algorithm = ata_secure_erase
     enable_verification = true
     
     [ui]
     confirm_operations = true
     show_warnings = true

2. Implementation

   • Parse config file at startup
   • Override with command-line arguments
   • Validate configuration values
   • Provide sample config file

3. Documentation

   • Document all available options
   • Provide example configurations
   • Explain override priority

Acceptance Criteria

• Config file parser implemented
• All major settings configurable
• Sample config file provided
• Documentation complete
• Graceful handling of missing/invalid config
