MetaWalletGen CLI is designed with security as a top priority. This document outlines our security features, best practices, and responsible disclosure policy.

• AES-256 Encryption: All sensitive data is encrypted using industry-standard AES-256 encryption
• PBKDF2 Key Derivation: Password-based key derivation with configurable iterations (default: 100,000)
• Secure Random Generation: Uses cryptographically secure random number generation via secrets module
• Memory Protection: Sensitive data is cleared from memory after use
• No Persistent Storage: Private keys and mnemonics are never stored in plain text

• Comprehensive Validation: All user inputs are validated before processing
• Type Safety: Strong type checking and validation for all parameters
• Range Validation: Ensures all numeric values are within safe ranges
• Format Validation: Validates addresses, private keys, and mnemonic phrases
• Network Validation: Restricts operations to supported networks only

• Password Strength Requirements: Configurable minimum password length (default: 8 characters)
• Environment Variable Support: Secure password injection for automation
• No Password Logging: Passwords are never logged or displayed
• Confirmation Prompts: Password confirmation for critical operations

• No Sensitive Data Logging: Private keys, mnemonics, and passwords are never logged
• Secure File Handling: All file operations use secure encoding and error handling
• Temporary Data: Sensitive data is only held in memory temporarily
• Cleanup Procedures: Automatic cleanup of sensitive data after operations

1. Never share private keys or mnemonic phrases
2. Use strong, unique passwords for encrypted files
3. Store encrypted files in secure locations
4. Regularly backup wallet data securely
5. Use environment variables for automation passwords
6. Verify file integrity after operations
7. Keep the tool and dependencies updated

1. Never log sensitive information
2. Always validate user inputs
3. Use secure random number generation
4. Implement proper error handling
5. Follow secure coding practices
6. Regular security audits of dependencies
7. Test security features thoroughly

1. Restrict access to wallet files
2. Use secure file permissions
3. Monitor for unauthorized access
4. Implement logging for security events
5. Regular security updates
6. Backup security policies

• Encryption Tests: Verify encryption/decryption functionality
• Validation Tests: Test input validation and sanitization
• Memory Tests: Ensure sensitive data is properly cleared
• Error Handling Tests: Verify secure error handling
• Integration Tests: Test complete security workflows

• Code Review: Regular security-focused code reviews
• Dependency Audits: Regular security audits of third-party libraries
• Penetration Testing: Periodic security testing by qualified professionals
• Vulnerability Assessment: Regular assessment of potential security issues

If you discover a security vulnerability in MetaWalletGen CLI, please follow these steps:

1. DO NOT create a public issue on GitHub
2. DO NOT discuss the vulnerability publicly
3. Email security details to: security@metawalletgen-cli.com
4. Include detailed description of the vulnerability
5. Provide steps to reproduce the issue
6. Wait for acknowledgment and response

• Initial Response: Within 48 hours
