I have a Json let obj = {"a": "1", "b" : "2"} which contain whitespaces. I want to serialize the obj without removing the whitspaces, So that when i deserialize (EX: using JSON.parse()), i should be able to get the obj in same format.

let obj = {"a":   "1",  "b" :    "2"};
let serialized_obj = JSON.stringify(obj);
//then we get  serialized_obj  = "{"a":"1","b":"2"}" , this shouldn't happen.

What is Expected?

let obj = {"a":   "1",  "b" :    "2"};
let serialized_obj = serializationMethod(obj);
// expected to get serialized_obj  = "{"a":   "1",  "b" :    "2"}"
let deserialized_obj = deserializationMethod(serialized_obj);
//expected to get serialized_obj  = {"a":   "1",  "b" :    "2"}

Require the methods serializationMethod() and deserializationMethod()

More Details For security reasons i get the JSON object and the digital signature of the serialized object. i have to verify the both. I can get these from any of the technology user. But the problem i faced is, in python serialization the json is beautified with whitespaces. So when i get them, i am not able to keep the format i got and verificaton fails.
