csprpg

csprpg

basic cryptographically secure pseudo-random password generator based on node crypto's randombytes or webCrypto.getRandomValues in the browser.

Example

import csprpg from 'csprpg'
const log = label => console.log.bind(console, label)

const spec = {
  length: 16, // characters, default 12, min 4, max 4096
  lowercase: true, // default
  numbers: true, // default
  symbols: '!$?#@+-=', // default true = `^!$%&/{([)]=}?\\+*~#<>|,;.:-_`
  uppercase: true // default
}

log('sync')(csprpg(spec))

csprpg(spec, log('async'))

API v1

export default function csprpg (
  opts?: Partial<CsprpgSpec> | CsprpgCallback,
  cb?: Partial<CsprpgSpec> | CsprpgCallback
): string

export interface CsprpgSpec {
  randombytes: typeof randombytes
  length: number
  lowercase: boolean | string
  uppercase: boolean | string
  numbers: boolean | string
  symbols: boolean | string
}

export interface CsprpgCallback {
  (err?: any, rnd?: string): void
}

TypeScript

although this library is written in TypeScript, it may also be imported into plain JavaScript code: code editors will still benefit from the available type definition, e.g. for helpful code completion.
