purecrypt

Ultralight string encryption, decryption, and validation package.

Description

Use Purecrypt to quickly encrypt, decrypt, or validate any string on your Node.js project.

How to Use

Set up your .env...

// Can be any statement
CRYPTO_KEY=Super secret key

// See supported ciphers below
ALGO=aes-256-cbc

Encrypt any string...

require('dotenv').config()
const purecrypt = require('purecrypt')

...

let encryptedSample = purecrypt.encrypt('example');

Decrypt any previously encrypted string... Note: CRYPTO_KEY and ALGO in .env must match what was used to encrypt the string.

purecrypt.decrypt(encryptedSample)

Validate any previously encrypted string with an incoming string. Useful for password validation. Accepts existing encrypted string, then incoming string to validate.

router.post('login', async (req, res) => {
  let { username, password } = req.body;
  try {
    const user = await Users.findBy({ username });
    if ( user && purecrypt.validate(user.password, password) ){
      ...
    } else {
      ...
    }
  } catch(e) {
    res.status(500).json({ error: e.message })
  }
})
