Token Generator Online

This is an online token generator tool that allows you to generate secure, random tokens for a variety of use cases, such as:

• Authentication: Generate unique tokens for user authentication, password reset, or other security-sensitive operations.
• API Access: Create access tokens for authorizing and identifying API clients.
• Unique Identifiers: Generate random IDs for various applications, such as user accounts, transactions, or other entities.

The token generator utilizes the browser's cryptographic API to ensure the generated tokens are truly random and secure. You can customize the token length and character set (uppercase letters, lowercase letters, and numbers) to fit your specific requirements.

How to Use the Token Generator

• Select Token Length: Choose the desired length of the token, ranging from 20 to 100 characters.
• Choose Token Number: Set how many token you need to generate at one time. Our online service supports setting values from 10 to 100.
• Generate Token: Click the "Bulk Generate" button to create a new, secure token.
• Copy Token: The generated token will be displayed, and you can easily copy it to your clipboard for use in your application.

Features

• Secure Token Generation: Utilizes the browser's cryptographic API to generate truly random and secure tokens.
• Customizable Token Length: Choose token lengths from 8 to 64 characters.
• Flexible Character Set Selection: Include uppercase letters, lowercase letters, and/or numbers in the token.
• Easy to Use: Simple and intuitive interface for generating tokens quickly.
• No Server-side Dependencies: The token generator runs entirely in the browser, without the need for a backend server.

Use Cases

• Authentication: Generate unique tokens for user authentication, password reset, or other security-sensitive operations.
• API Access: Create access tokens for authorizing and identifying API clients.
• Unique Identifiers: Generate random IDs for various applications, such as user accounts, transactions, or other entities.
• Secure Communication: Use the generated tokens as part of a secure communication protocol, such as in headers or query parameters.

Typescript Token Generator

This TypeScript code implements a function generateToken that generates a secure token using the browser's crypto API.

/**
 * Generates a secure token using the browser's crypto API.
 * @param length - The desired length of the token.
 * @param options - Optional configuration options.
 * @param options.uppercase - Include uppercase letters. Default is true.
 * @param options.lowercase - Include lowercase letters. Default is true.
 * @param options.numbers - Include numbers. Default is true.
 * @returns A secure token.
 */
export function generateToken(
  length: number,
  options?: {
    uppercase?: boolean;
    lowercase?: boolean;
    numbers?: boolean;
  }
): string {
  const { uppercase = true, lowercase = true, numbers = true } = options || {};

  let charset = "";
  if (uppercase) charset += "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
  if (lowercase) charset += "abcdefghijklmnopqrstuvwxyz";
  if (numbers) charset += "0123456789";

  if (charset.length === 0) {
    throw new Error("At least one character set must be selected.");
  }

  const buffer = new Uint8Array(length);
  window.crypto.getRandomValues(buffer);

  let token = "";
  for (let i = 0; i < length; i++) {
    token += charset[buffer[i] % charset.length];
  }

  return token;
}

How to Use?

1. Import the function:

import { generateToken } from "./token-generator";

2. Generate a default 16-character token:

const token = generateToken(16);
console.log(token); // Output: 'a3Bh2Cd9Ef5Gh7Ij'

3. Generate a custom-length token with specific character sets:

const customToken = generateToken(20, {
  uppercase: true,
  lowercase: false,
  numbers: true,
});
console.log(customToken); // Output: '7892345678901234567'

4. Handle invalid configurations:

try {
  const invalidToken = generateToken(10, {
    uppercase: false,
    lowercase: false,
    numbers: false,
  });
} catch (error) {
  console.error(error); // Output: Error: At least one character set must be selected.
}

Handle Token Storage And Transmission Securely

To ensure the secure handling of tokens, adhere to the following guidelines:

• Store Tokens Securely: Utilize secure, server-side storage to maintain token confidentiality. Refrain from storing tokens in local storage or other client-side locations that can be accessed via client-side scripts.

• Use HTTPS: Transmit tokens exclusively over secure channels. Employ HTTPS to encrypt the communication between the client and the server, safeguarding tokens from interception during transmission.

• Access Controls: Ensure that tokens are accessible only to authorized systems and services. Implement strict access controls to prevent unauthorized access.

• Monitoring and Logging: Keep track of token usage and log access events to facilitate the detection and response to unauthorized use or potential security breaches.

By following these best practices, you can help guarantee that tokens are managed securely throughout their lifecycle.
