cryptr

cryptr is a simple aes-256-gcm encrypt and decrypt module for node.js

It is for doing simple encryption of values UTF-8 strings that need to be decrypted at a later time.

If you require anything more than that you probably want to use something more advanced or crypto directly.

The Cryptr constructor takes 1 required argument.

Cryptr(secret)

The salt and iv are randomly generated and prepended to the result

DO NOT USE THIS MODULE FOR ENCRYPTING PASSWORDS!

Passwords should be a one way hash. Use bcrypt for that.

Install

npm install cryptr

Usage

const Cryptr = require('cryptr');
const cryptr = new Cryptr('myTotalySecretKey');

const encryptedString = cryptr.encrypt('bacon');
const decryptedString = cryptr.decrypt(encryptedString);

console.log(encryptedString); // e7b75a472b65bc4a42e7b3f78833a4d00040beba796062bf7c13d9533b149e5ec3784813dc20348fdf248d28a2982df85b83d1109623bce45f08238f6ea9bd9bb5f406427b2a40f969802635b8907a0a57944f2c12f334bd081d5143a357c173a611e1b64a
console.log(decryptedString); // bacon
