-===== JSON Decryption =====
-This code works with a JSON stream encrypted with CryptoJS. You can use PHP with openSSL support to decrypt the data stream using your password.

-    $jsondata = json_decode($jsonString, true);
-    $salt = hex2bin($jsondata["s"]);
-    $ct = base64_decode($jsondata["ct"]);
