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('myTotallySecretKey');

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

console.log(encryptedString); // 2a3260f5ac4754b8ee3021ad413ddbc11f04138d01fe0c5889a0dd7b4a97e342a4f43bb43f3c83033626a76f7ace2479705ec7579e4c151f2e2196455be09b29bfc9055f82cdc92a1fe735825af1f75cfb9c94ad765c06a8abe9668fca5c42d45a7ec233f0
console.log(decryptedString); // bacon
