First argument must be a Buffer (msgpack + forge aes encryption)

[carlosjpr-collab]

I am trying to excute this code that do

• read json file

• change json to message pack

• encrypt the new json

• decypt the new json

• change json message pack to normal json (here is my error)

• var fs = require('fs'); var forge = require('node-forge'); var msgpack = require('msgpack');

  file = [] x= null fs.readFile(process.cwd() + "/test.json", function(err, data) { file = data // json = JSON.stringify(JSON.parse(file),null,2); packedFile = msgpack.pack(file) key = 'SdI6qAn1602f942'

  // encrypt some bytes using ECB mode var cipher = forge.cipher.createCipher('AES-ECB', key); cipher.start(); cipher.update(forge.util.createBuffer(packedFile)); cipher.finish(); var encrypted = cipher.output;

  // decrypt some bytes using ECB mode var decipher = forge.cipher.createDecipher('AES-ECB', key); decipher.start(); decipher.update(encrypted); decipher.finish(); // check 'result' for true/false // outputs decrypted console.log(msgpack.unpack(decipher.output.data)) });

  But I am getting this error in this line:

  console.log(msgpack.unpack(decipher.output.data)) Uncaught TypeError: First argument must be a Buffer

My test file is any json file

{ "testin": "test" }

Hello @carlosjpr-collab ,

did you try decipher.update(forge.util.createBuffer(encrypted)) instead of decipher.update(encrypted); ?
