Description

Some users would like to decrypt their response with AES-128 by using the Scripting Tool. We should support it 👍

It's done with this BETA build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.15.0_Support_Crypto_Addon.dmg

Support Encryption/Decryption for AES, DES and Rabbit
It's a wrapper of Crypto-JS https://cryptojs.gitbook.io/docs/

Sample code:

// Addons List: https://docs.proxyman.io/scripting/addons
const { sayHello } = require("@addons/HelloWorld.js");
const { decryptAES } = require("@addons/CryptoJS.js")

function onRequest(context, url, request) {
  
  // Decrypt AES
  var ciphertext = 'U2FsdGVkX1+sCIKOY6nMXWAJtkZn9jSUA+/3g+HXuAdcyqKFHLlXkgPAR+lK5Xw4';
  var password = 'secret key 123';
  var originalText = decryptAES(ciphertext, password);
  console.log(originalText);

  // Done
  return request;
}

function onResponse(context, url, request, response) {

  // Done
  return response;
}

How the CryptJS.js (~/Library/Application Support/com.proxyman.NSProxy/addons/CryptoJS.js) looks like
