Decryption middleware for express.

At the moment library decrypts only body from requests.

Install

yarn add express-request-decrypt

or

npm i -S express-request-decrypt

Usage

Code example:

import compareVersion from 'compare-versions'
import CryptoJS from 'crypto-js'
import express from 'express'
import { createDecryptMiddleWare } from 'express-request-decrypt'

const app = express.Router()

app.use(createDecryptMiddleWare({
  allowNotEncrypted: process.env.NODE_ENV === 'test',
  onDecrypt(encTxt) {
    return CryptoJS.AES.decrypt(encTxt, 'secret').toString(CryptoJS.enc.Utf8)
  },
  isEncryptionRequired(req) {
    // (optional) if you need to disable for some requests
    const appVersion = req.headers['app-version']
    const diff = compareVersion(appVersion, '1.0')
    return diff >= 0 // starting from 1.0
  },
}))
