What the n-krypta package does

n-krypta is an npm package that runs on the nodejs environment . It allows you to encrypt and decrypt sensitive data using a key. It is based on a strong algorithm. This library is available on npm and it is compatible with nodejs on both the client and server side. It can run on any javascript or typescript project (Nodejs, Reactjs, Vuejs, Angularjs etc). It allows encryption and decryption of strings, numbers, booleans, objects, arrays, null and undefined.


npm install n-krypta  //for npm


yarn add n-krypta //for yarn


It can be used on nodejs, react, angular, vue, and any other javascript or typescript project.

Data types supported

  • string
  • number
  • boolean
  • object
  • array
  • null
  • undefined
const { encrypt, decrypt, compare } = require('n-krypta'); //For commonjs


import { encrypt, decrypt, compare } from 'n-krypta'; //For es6

Encryption and Decryption of strings

const secret = 'my-secret'; // secret key for encryption
const sampleString =
  'I am not sure where you are getting your information, but good topic. I needs to spend some time learning more or understanding more. Thanks for excellent info I was looking for this info for my mission.';

const encryptedString = encrypt(sampleString, secret); // #Iblankartan!not!svreblankartwhfreblankartzpublankartase!gettiogblankartypvrblankartiofprmatipn,blankartcvtblankartgpoeblankarttopid.blankartI!oeedtblankartuoblankartspeodblankartspneblankarttjmfblankartlearoing!nore!osblankartundesstaoeing!mpre.blankartTiankt!for!eycelleotblankartiogoblankartI!wbsblankartlooling!gorblankartuhjsblankartinfpblankartfos!myblankartnitsion.#

console.log(encryptedString); // This prints out the encrypted string

const decryptedString = decrypt(encryptedString, secret); // decrypts the string

console.log(decryptedString); // This prints out the decrypted string

Encryption and Decryption of objects

const secret = 'my-secret'; // secret key for encryption
const sampleObject = {
  name: 'Samuel Egbajie',
  age: infinity,
  address: 'earth, Universe',
  email: '[email protected]',
  phone: '08012345678',
  password: 'my-password',

const encryptedObject = encrypt(sampleObject, secret); //|killernanfkiller:killerTanuelblankartEhbajjfkiller,killerbgfkiller:nulm,killeraeerestkiller;alphakillerstrfetkiller;#MaioblankartTtreet#,killernvnber#:223mega,killerfmaim#:[email protected],#pionekiller:#08023345779killer,killerpatswosekiller:killerny.passwprdkiller-#lanhubgeskiller:blacardkillerMbvcekiller,#NbijablankartPjdgio#,killerJbvbScripukiller,killero.kryqtbkiller,killerEnhlisi#,killerAsacickiller,killerEeuttdhekiller^mega

console.log(encryptedObject); // This prints out the encrypted object as string

const decryptedObject = decrypt(encryptedObject, secret); // decrypts the string

console.log(decryptedObject); // This prints out the decrypted object

Encryption and Decryption of arrays

const secret = 'my-secret'; // secret key for encryption
const sampleArray = [

const encryptedArray = (encryptedArray = encrypt(sampleArray, secret)); //blacardkillerOrboges#,#Appletkiller,killerCbnanbs#,killerGraqeskiller-#Peass#,killerPinfappmfskiller,#Wbtermemons#-killerMaogpeskiller],killerPinfappmfskiller,#Wbtermemons#-killerMaogpeskiller]

console.log(encryptedArray); // This prints out the encrypted array as string

const decryptedArray = decrypt(encryptedArray, secret); // decrypts the string

console.log(decryptedArray); // This prints out the decrypted array

Comparing encrypted strings (example for password comparison)

const secret = 'Secret'; // secret key for encryption
const samplePassword = '[email protected]';

const encryptedPassword = encrypt(samplePassword, secret); // #Nz.qatsword1:11A#

// This returns true if the password matches the encrypted password
const passwordMatch = compare(samplePassword, encryptedPassword, secret); // true

console.log(passwordMatch); // This prints out true

// This returns false if the password does not match the encrypted password
const passwordMatch = compare('wrong-password', encryptedPassword, secret); // false

console.log(passwordMatch); // This prints out false
