🛡️ Ethical Guidelines

Before You Start

1. Get Written Authorization: Always obtain explicit written permission before testing
2. Understand the Scope: Know exactly what you're allowed to test
3. Follow Responsible Disclosure: Report findings appropriately
4. Respect Rate Limits: Don't overwhelm target systems
5. Document Everything: Keep detailed records of your testing

Best Practices

# Good: Respectful testing with delays
config = ScanConfig(
    url="https://your-app.com/test",
    delay=1.0,  # 1 second between requests
    max_payloads_per_type=5,  # Limited payloads
    timeout=10.0  # Reasonable timeout
)

# Good: Targeting specific parameters
config = ScanConfig(
    url="https://your-app.com/search",
    test_parameters=["q"],  # Only test the search parameter
    injection_types=[InjectionType.BOOLEAN_BLIND]  # Less intrusive
)

Reporting Vulnerabilities

When you find vulnerabilities:

1. Document Thoroughly: Include payload, response, and impact
2. Provide Remediation: Suggest fixes and best practices
3. Follow Disclosure Timeline: Give developers time to fix issues
4. Be Professional: Communicate clearly and respectfully

🔬 Advanced Features

Database Fingerprinting

from sqlinjector.payloads import PayloadManager

# Get database-specific payloads
manager = PayloadManager()
mysql_payloads = manager.get_detection_payloads()["mysql"]

Custom Payload Development

from sqlinjector.payloads import PayloadManager
from sqlinjector.models import InjectionType

# Add custom payloads
manager = PayloadManager()
custom_payloads = [
    "' AND (SELECT COUNT(*) FROM information_schema.tables)>0--",
    "' AND (SELECT SUBSTRING(@@version,1,1))='5'--"
]

manager.add_custom_payloads(InjectionType.BOOLEAN_BLIND, custom_payloads)

Integration with Security Tools

# Integration example for security scanners
import asyncio
from sqlinjector import VulnerabilityScanner
from sqlinjector.models import ScanConfig

class SecurityScanner:
    def __init__(self):
        self.sql_scanner = None
    
    async def scan_for_sql_injection(self, target_url, **kwargs):
        config = ScanConfig(url=target_url, **kwargs)
        scanner = VulnerabilityScanner(config)
        return await scanner.scan()
    
    def format_findings(self, result):
        return {
            "tool": "SQLInjector",
            "vulnerabilities": len(result.vulnerabilities),
            "severity": "high" if result.get_critical_vulnerabilities() else "medium",
