HTTP Toolkit UI Pro takes security seriously and is committed to protecting our users and maintaining a secure development ecosystem. This document outlines our security practices and procedures.

• Content Security Policy (CSP): Prevents XSS attacks by restricting resource loading
• Input Sanitization: All user inputs are sanitized using DOMPurify
• HTTPS Enforcement: Automatic redirection to secure connections
• Secure Headers: Implementation of security-focused HTTP headers
• Dependency Scanning: Automated vulnerability scanning of dependencies

• Local Storage: Sensitive data is stored securely in browser's local storage
• Encryption: Client-side encryption for sensitive configuration data
• No Data Collection: No personal data is collected without explicit consent
• Privacy by Design: Privacy considerations built into all features

Please do not report security vulnerabilities through public GitHub issues.

Instead, send your report to:

• Email: security@httptoolkit.com
• PGP Key: Available on our website for encrypted communications

// ✅ Secure: Validate and sanitize all inputs
import DOMPurify from 'dompurify';

export const sanitizeUserInput = (input: string): string => {
    return DOMPurify.sanitize(input, {
        ALLOWED_TAGS: ['b', 'i', 'em', 'strong'],
        ALLOWED_ATTR: ['class'],
        ALLOW_DATA_ATTR: false
    });
};

// ❌ Insecure: Direct use of user input
export const insecureExample = (input: string) => {
    return <div dangerouslySetInnerHTML={{ __html: input }} />;
};

// ✅ Secure: Proper session management
export const secureAuth = {
    login: async (credentials: Credentials) => {
        const response = await api.login(credentials);
        if (response.token) {
            // Store token securely
            await secureStorage.setItem('authToken', response.token);
            return true;
        }
        return false;
    },
    
    logout: async () => {
        await secureStorage.removeItem('authToken');
        await api.logout();
    }
};

// ❌ Insecure: Storing tokens in localStorage
export const insecureAuth = {
    login: async (credentials: Credentials) => {
        const token = await api.login(credentials);
        localStorage.setItem('token', token); // Vulnerable to XSS
    }
};

// ✅ Secure: Proper error handling
export const secureApiCall = async (endpoint: string) => {
    try {
        const response = await fetch(endpoint, {
            headers: {
                'Content-Type': 'application/json',
                'X-CSRF-Token': getCsrfToken()
            }
        });
        
        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }
        
        return await response.json();
    } catch (error) {
        // Log error without exposing sensitive information
        console.error('API call failed:', error.message);
        throw new Error('Request failed');
    }
};
