Password Generator

A simpel command line utility for generating passwords.
The program is designed to be used in a terminal via manual user input or via a command line interface.

About

This program was created during an evening of four hours as part of a coding challenge called Projlett, which is a hackathon designed as a way to learn and improve programming skills and expand my knowledge of the TypeScript programming language and it’s ecosystem.

In Projlett, you submit a small set of simpel ideas and concepts that you think are unique and that somebody else might be able to implement. In return, you get a random idea that you shall implement in the best way you possible can during a limited time. This is a great way to learn new things and to get a sense of how to implement something in a real world scenario.

CLI Installation

You can install the CLI tool by running the following command:

deno install -A -f -n pass https://deno.land/x/pass/cli.ts

Or run it without installing it, using land:

land pass

CLI Usage

Manual User Input

Run the password generator through the interactive user interface by typing pass in the terminal.

Library Usage

The library is also designed to be used in a Deno environment. Not only as a command line utility. Import the password generator library and use it as follows:

import { generatePassword } from "https://deno.land/x/pass/mod.ts";

const length = 20;
const numbers = true;
const specials = true;
const password = generatePassword(length, numbers, specials);
console.log(`Generated password: ${password}`);

Use with JavaScript

The library is bundled to a JavaScript file that can be used in a browser. Link to the script file using:

<script src="https://cdn.deno.land/pass/versions/1.2.2/raw/dist/pass.bundle.js"></script>

This will load the library and provide global functions called generatePassword and generateCharset.
