Generating Bcrypt in TypeScript

TypeScript is an open-source programming language developed by Microsoft. It is a superset of JavaScript, which means that any valid JavaScript code is also valid TypeScript code. The main feature of TypeScript is that it adds a static type system to JavaScript, enabling developers to catch potential type errors during the coding phase, thereby improving code quality and development efficiency.

The design goal of TypeScript is to provide an optional type system for JavaScript to support the development of large-scale applications and to assist in maintaining and understanding the code. It allows developers to define interfaces, classes, enums, and type aliases, which are features not present in JavaScript. These features make TypeScript highly suitable for large-scale projects and enterprise-level development.

1: Using the bcryptjs library

bcryptjs is a library written purely in JavaScript and can be used in both Node.js and browsers. Here is an example of how to use the bcryptjs library:

Install the bcryptjs library:

npm install bcryptjs

Generate a Bcrypt hash:

import * as bcrypt from "bcryptjs";

// Synchronization method
const saltRounds = 10;
const password = "mySecurePassword";
const hash = bcrypt.hashSync(password, saltRounds);
console.log("Hashed password:", hash);

// Asynchronous method
bcrypt.hash(password, saltRounds, (err, hash) => {
  if (err) {
    console.error("Error hashing password:", err);
  } else {
    console.log("Hashed password:", hash);
  }
});
import * as bcrypt from "bcryptjs";

// Synchronization method
const saltRounds = 10;
const password = "mySecurePassword";
const hash = bcrypt.hashSync(password, saltRounds);
console.log("Hashed password:", hash);

// Asynchronous method
bcrypt.hash(password, saltRounds, (err, hash) => {
  if (err) {
    console.error("Error hashing password:", err);
  } else {
    console.log("Hashed password:", hash);
  }
});

Verify a password:

import * as bcrypt from 'bcryptjs';

const password = 'mySecurePassword';
const hash = '$2a$10$...', // Replace this with the actual hash value.

bcrypt.compare(password, hash, (err, result) => {
  if (err) {
    console.error('Error verifying password:', err);
  } else {
    console.log('Password match:', result); // true if matched
  }
});

2. Using the bcrypt-ts library

bcrypt-ts is an optimized Bcrypt library written in TypeScript, suitable for both Node.js and browser environments. Here is an example of how to use the bcrypt-ts library:

Install the bcrypt-ts library:

npm install bcrypt-ts

Generate a Bcrypt hash:

import { genSaltSync, hashSync } from "bcrypt-ts";

const salt = genSaltSync(10);
const hash = hashSync("B4c0//", salt);
console.log("Hashed Password:", hash);

Verify a password:

import { compareSync } from "bcrypt-ts";

const password = "B4c0//";
const hash = "$2a$10$..."; // Replace this with the actual hash value.
const result = compareSync(password, hash); // true
console.log("Password match:", result);

3. Using the bcrypt library

bcrypt is another popular password hashing library suitable for the Node.js environment. Here is an example of how to use the bcrypt library:

Install the bcrypt library:

npm install bcrypt

Generate a Bcrypt hash:

import * as bcrypt from "bcrypt";

const saltRounds = 10;
const password = "mySecurePassword";
const hash = bcrypt.hashSync(password, saltRounds);
console.log("Hashed password:", hash);

Verify a password:

import * as bcrypt from "bcrypt";

const password = "mySecurePassword";
const hash = "$2a$10$..."; // Replace this with the actual hash value.
const result = bcrypt.compareSync(password, hash); // true
console.log("Password match:", result);

These are several methods for generating Bcrypt hashes in TypeScript. Each method has its characteristics and applicable scenarios. You can choose the appropriate library for password hashing based on your project's needs.
