byteskode-keygen

byteskode key generator utility

Installation

$ npm install --save byteskode-keygen

Usage

var keygen = require('byteskode-keygen');

//generate key
keygen.generate(<payload>, function(error, key){
    ...
});

//verify key
keygen.verify(<key>, <payload>, function(error, isValid){
    ...
});

Options

Internal configuration of byteskode-keygen can be altered by set a value to a specific options. The structure of the options is

{
    encryption: 'md5', //encryption algorithm
    encoding: 'hex', //encoding format
    keyLength: 20, //default key length
    chunkSize: 4, //chuck of keys to be formatted
    format: true, //format generated key
    separator: '-', //key separator 
    secret: undefined //encyption key default to machine id
}

To alter any configuration just pass your option overrides as

var keygen = require('byteskode-keygen');

//change encryption algorithm
keygen.options.encryption = 'sha256';

To restore default settings

var keygen = require('byteskode-keygen');

keygen.restore();

{ 
  prefix: 'E43427',

  suffix: 'D2639D',
  secret: 'be9d373a4e73de831216c228cb729c71' 
}

Where

• prefix - Part of the key extracted to be used as prefix in verification
• key - The actual key with default length of 20 characters
• suffix - Part of the key extracted to be used as suffix in verification
• secret - A secret key used in generating a key
