为假人在JS和C＃之间共享加密的数据

Question

My team must share data between a localnet html/js app, and a server in the same net listening on a websocket. The first idea was to simply send variables to the server with get

http://192.168.1.100:8080/var=hello

It's simple and works, but we must add a security level to the data exchange, encrypting all in Aes and then hexing the result to send it as plain string.

The best solution that we found is Crypto-JS https://code.google.com/p/crypto-js/ We are able to follow the examples and encrypting/decrypting data inside the same js block, but are unable to decrypt the data on another software.

we do:

var text = "Message";
var password = "Secret Passphrase";

var encrypted = CryptoJS.AES.encrypt(text, password);

var EnText = encrypted.ciphertext; //returns the hexed/encrypted text
var Key = encrypted.key;

It doesn't work with the c# code running on the server, so we tried an online decrypting tool http://aes.online-domain-tools.com/ passing both the password and the Key, but similarly returns unreadable text

JS generated value for reference

EnText: 5768c9b4d75e0cc32b610d9e6f518c36
Key: 005e316192f5162f7fd104ce2c9fe91de6c6f2977849dcd5878226022a7073be

What are we missing?

Answer 1

Ok i got it, the text is in hexadecimal. Try decyphering it there:
