ios - CryptoSwift + CryptoJS Swift -

i need here decrypting server response encrypted cryptojs.

i use cryptoswift decrypt response.

here sample of server response data get.

simple string parsing clears encrypted string , gives me following data:

let iv = "d6d6bd8ee407bc25a7b23d8d36b7bce9"  let salt = "b8e72892c801c87c" 

and key formend other data

let key = "8aa1ec1e6948b481d1ee450c94ffb2edc774877325df4d05aca2e5827497ed33" 

here peace of code use decrypt response:

// transforming key [uint8]     let keychars = array(key.characters)     let keybytes = 0.stride(to: keychars.count, by: 2).map {         uint8(string(keychars[$0 ..< $0+2]), radix: 16) ?? 0     }      // transforming iv [uint8]     let ivchars = array(iv.characters)     let ivbytes = 0.stride(to: ivchars.count, by: 2).map {         uint8(string(ivchars[$0 ..< $0+2]), radix: 16) ?? 0     }      // transforming encrypteddata [uint8]     let messagedata = encrypted.datafromhexadecimalstring()     let bytearray = messagedata!.arrayofbytes()       {         let decryptedbytes: [uint8] = try aes(key: keybytes, iv: ivbytes, blockmode: .cfb).decrypt(bytearray)         let data = nsdata.withbytes(decryptedbytes)         let decrypted = data.base64encodedstringwithoptions([])         let json = try nsjsonserialization.jsonobjectwithdata(data, options: nsjsonreadingoptions())         print("decrypted = \(json)")     } catch {         print("error = \(error)")     } 

what ever either error = decrypt or base64 string not decode json suppose to.

p.s.: did try cryptojs.swift result "undefined"

upd

sample project how data encrypted on end:

cryptojs.aes.encrypt(json.stringify(options.params), key, { format: jsonformatter }).tostring() 

this how data decrypted on end:

json.parse(cryptojs.enc.utf8.stringify(cryptojs.aes.decrypt(raw, key, { format: jsonformatter }))) 

i tried to similar in sample project reason did not work me.

upd2

update end

// nodejs import var node_cryptojs   = require('node-cryptojs-aes'); var cryptojs        = node_cryptojs.cryptojs; var jsonformatter   = node_cryptojs.jsonformatter; // data encrypt , encryption key var data            = {'hello':'world'}; var key             = '8aa1ec1e6948b481d1ee450c94ffb2edc774877325df4d05aca2e5827497ed33'; // encryption of data var encrypted       = cryptojs.aes.encry  var decrypted       = json.parse(cryptojs.enc.utf8.stringify(cryptojs.aes.decrypt(encrypted, key, { format: jsonformatter }))) 

upd3

no, name similar api different. used npmjs.com/package/node-cryptojs-aes on server-side (encryption+ decryption) , code.google.com/archive/p/crypto-js client-side on our site (also encryption+decryption)
