[JeelDobariya38]

Changes Made

• add a basic password generator.
• it supports character preference like letters, numbers, symbols & length.

Notes

thanks to @jainil63 for contributing the password generator code under the event of "Beginner Fest | Contribution Race" in discord.

@razorblade23 can pls suggest what can be done? Is ai correct or my version is just fine cuz, i thing we just generating password here so if the crypto is predictable it okay i guess

AI is right, you should never use basic random generator for something secure, like passwords.

In node, you can use randomInt from node.crypto module as in this example (generated with AI - use caution):

import { randomInt } from 'node:crypto';

/**
 * Generates a cryptographically secure random password.
 * @param {number} length - The length of the password (default: 16).
 * @returns {string} The generated password.
 */
export function generateSecurePassword(length = 16) {
  const lowercase = 'abcdefghijklmnopqrstuvwxyz';
  const uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  const numbers = '0123456789';
  const symbols = '!@#$%^&*()_+-=[]{}|;:,.<>?';
  
  const charset = lowercase + uppercase + numbers + symbols;
  let password = '';

  for (let i = 0; i < length; i++) {
    // randomInt securely picks an index between 0 (inclusive) and charset.length (exclusive)
    const randomIndex = randomInt(0, charset.length);
    password += charset.charAt(randomIndex);
  }

  return password;
}

// Example usage:
const securePassword = generateSecurePassword(18);
console.log(securePassword);
