Installation

npm i @eli.richardson/pass-js

Usage

Word generator mode:

Note: await or .then is only needed for loading the dictionary for word generator mode

With await

import PassJS from "@eli.richardson/pass-js";

const password = new PassJS();

await password.init();
console.log(password.make(options));

With .then

import PassJS from "@eli.richardson/pass-js";

const password = new PassJS();

password.init().then(() =>
    console.log(password.make(options))
    );

"Traditional" mode:

import PassJS from "@eli.richardson/pass-js";

const options = {traditional: true};
const password = new PassJS();

console.log(password.make(options));

Examples:

Word generator:

import PassJS from "@eli.richardson/pass-js";
const password = new PassJS();
await password.init();
console.log(password.make({
    words: 3,
    separator: "-",
    amount: 2
}));

Output:

[ 'jesuits-chest-hope', 'split-earring-bury' ]

Traditional:

import PassJS from "@eli.richardson/pass-js";
const password = new PassJS();
console.log(password.make({
    traditional: true,
    min: 8,
    lower: true,
    upper: true,
    number: true,
    symbol: true,
    amount: 2
}));

Output:

[ 'J*SH7ObM', 'eb%fhbl1' ]

Using a custom dictionary

PassJS comes preinstalled with a GZIP'd dictionary of popular.txt (words < 4 characters are removed).

PassJS can load a custom dictionary file, with each word separated by a newline \n

The dictionary file must be either plaintext or GZIP. I recommend GZIPing any large dictionaries to save space.

Creating a GZIP:

import { createGzip } from "zlib";
import fs from "fs";

const gzip = createGzip();
/*
uppers.txt.gz:
A
B
C
D
.
.
.
Z
*/

const read = fs.createReadStream("./uppers.txt");
const write = fs.createWriteStream("./uppers.txt.gz");

read.pipe(gzip).pipe(write);
// Creates "./uppers.txt.gz"

import PassJS from "@eli.richardson/pass-js";

const password = new PassJS();
await password.init("./uppers.txt");
// OR: "./uppers.txt.gz"
console.log(password.make({
    words: 4,
    amount: 2,
    separator: "-"
}));

Example output:

[ 'O_H_E_V', 'L_Z_P_Q' ]

PassJS Validator

PassJS comes with a password validator.

Usage

import PassJS from "@eli.richardson/pass-js";

const password = new PassJS();
const options = {
    number: true,
    lower: true,
    min: 4
}
password.validate("h3llo-world-maker", options);
// true
password.validate("hello-word-maker", options);
// false

Options

.make(<options>)

traditional - default: false

/*
Enables traditional mode.
Generates a password of specified min value.

Note: you can also set the words property to 0 for traditional mode.
*/
password.make({
    traditional: true
});
// Example value: "lnzdi9fp"

min - default: 8

/*
Resulting password length.

Note: only applied in traditional mode.
*/
password.make({
    traditional: true, 
    lower: true
    min: 30
});
// Example value: "aoajuovysrtxhuubdfsuvqxciwzymp"

words - default: 4

/*
Specifies the number of words in resulting password.

*/
password.make({

separator - default: _

/*
Set the separator for word mode.
Ex: If value is set to `!` result would be `<word>!<word>`

*/
password.make({

password.make({
    traditional: true,
    upper: true,
    number: true
});
// Example value: "Q0VOBLIY"
password.make({
    words: 3,
    upper: true
});
// Example value: "Breakwater_canary_racial"

number - default: false

/*
Inserts a number into a random position in the password.

*/
password.make({
    traditional: true,
    lower: true,
    number: true

// Example value: "4aihgnyl"
password.make({
    words: 2,

});
// Example value: "fpbcc^fj"
password.make({
    words: 2,
    symbol: true
});
// Example value: "accusation_infantile&"

space - default: false

/*
Inserts a space into a random position in the password.

Note: in word mode, this adds a space to a random word.
*/
password.make({
    words: 0,
    lower: true,
    space: true
});
// Example value: "ctxow ng"
password.make({
    words: 3,
    space: true

password.make({

password.make({
    words: 0,
    amount: 2,
    lower: true
});
// Example value: [ 'cuzwxpin', 'lcxalhsa' ]

Validation Options

The validator has the following boolean options:

• symbol - default: false
• upper - default: false
• lower - default: false
• number - default: false
• space - default: false

If enabled, it will return true if it is found at least once within the password.

The validator has the following numerical options:

• max - default: Infinity
• min - default: 0

If specified, the validator will return true if it is within the boundries.
