crypter-url-safe

Crypter - URL Safe

Description

Simple URL safe encryption and decryption. Uses AES-256-GCM with a random IV.

Use Cases

Encrypting and decrypting data in for a URL. Instead of having login?email=email you can have it be the encrypted version of the email. This is just a simple example but more secure than just having the email in the URL.

Warning Don't use for passwords

Use bcrypt for hashing passwords instead. Encrypting passwords is not the same as hashing them. This is not a password manager.

Secret Key

The secret key must be 32 bytes long. You can generate a random key with the following command.

openssl rand -hex 32

Usage

const Crypter = require('crypter-url-safe');
const crypter = new Crypter('db6a3d91aeaea2d91f69e91a6c033854b91d55e86393044bc9e7efb6e5bf5b2c');

const encrypted = crypter.encrypt('hello world'); // DB0Y5C38i32VVu9xk1nWY9qQ_YHo7V9UTF5hOecxHBDg57ibE7QvfGYk8p7EHo-jGv94_0iXyYEGDGPRDsrjv9z0iwHLWlT_t1PfcpC8SWGb6sXW64yblAiGOA
const decrypted = crypter.decrypt(encrypted);// hello world
