Security Utilities

Overview

This folder provides essential utilities to enhance web application security:

1. Sanitize User Input: Prevent injection attacks by sanitizing user inputs.
2. CSRF Token Generator: Generate secure tokens to prevent CSRF attacks.
3. Simple Hash Function for Obfuscation: Lightweight hashing function for quick obfuscation of strings.

Usage Examples

Sanitize User Input

import { sanitizeInput } from './Sanitize_User_Input.js';

const unsafeInput = "<script>alert('hack!')</script>";
const safeInput = sanitizeInput(unsafeInput);
console.log(safeInput); // Output: &lt;script&gt;alert('hack!')&lt;/script&gt;

CSRF Token Generator

import { generateCSRFToken } from './CSRF_Token_Generator.js';

const csrfToken = generateCSRFToken();
console.log(csrfToken); // Example: "MTIzNDU2Nzg5MGFiY2RlZg=="

Simple Hash Function

import { simpleHash } from './Simple_Hash_Function.js';

const input = "example";
const hashValue = simpleHash(input);
console.log(hashValue); // Example: 123456789

Features

• Sanitize User Input: Uses DOM manipulation for effective input sanitization.
• CSRF Token Generator: Leverages crypto API for secure, random token generation.
• Simple Hash Function: Provides a quick, easy-to-implement hashing mechanism.

Future Enhancements

• Add support for advanced sanitization based on HTML5 specifications.
• Introduce a cryptographically secure hash function.
