Dev Kit is a library that provides utilities for developers, facilitating the implementation of common functionalities.

🚀 Main Features

• ✅ Password Generation:
  • ✅ Simple Generation.
  • ✅ Generation with Crypto.

📦 Installation

You can install it using NPM:

npm install craft-kit

Or using Yarn:

yarn add craft-kit

Requirements

• NestJS (v9 or higher recommended).
• Node.js 16+

📌 Basic Usage in NestJS

Import the module:

import { Module } from "@nestjs/common";
import { UtilsModule } from "craft-kit";

@Module({
  imports: [UtilsModule],
})
export class AppModule {}

Password Generation

The library allows you to generate passwords using two main strategies.

SIMPLE Strategy

Use the SIMPLE strategy to generate a password with random characters:

import { PasswordFacade } from "craft-kit";
import type { ISimplePasswordParams } from "craft-kit";

const passwordFacade = new PasswordFacade(/* dependency injection in NestJS */);
const simpleParams: ISimplePasswordParams = {
  length: 12,
  useUppercase: true,
  useLowercase: true,
  useDigits: true,
  useSymbols: false,
};

const passwordSimple = passwordFacade.generatePassword("SIMPLE", simpleParams);
console.log("SIMPLE Password:", passwordSimple);

PBKDF2 Strategy

Use the PBKDF2 strategy for secure password generation, relying on a key derivation algorithm:

import { PasswordFacade } from "craft-kit";
import type { IPBKDF2PasswordParams } from "craft-kit";

const pbkdf2Params: IPBKDF2PasswordParams = {
  password: "miPasswordSecreto",
  salt: "salAleatoria",
  iterations: 100000,
  keylen: 64,
  digest: "sha512",
  encoding: "hex",
};

const passwordPBKDF2 = passwordFacade.generatePassword("PBKDF2", pbkdf2Params);
console.log("PBKDF2 Password:", passwordPBKDF2);

Registering New Strategies

If you want to extend the functionality, you can register custom strategies using the registerStrategy method:

passwordFacade.registerStrategy("CUSTOM", myCustomPasswordStrategy);

Direct Use of the Password Service

You can also use the PasswordService to dynamically switch strategies:

import { PasswordService } from "craft-kit";
import { SimplePassword } from "craft-kit";

const passwordService = new PasswordService(new SimplePassword());
const generated = passwordService.generatePassword({
  length: 10,
  useUppercase: true,
  useLowercase: true,
  useDigits: true,
  useSymbols: true,
});
console.log("Generated Password:", generated);
