Traversing JSON data in a recursive manner without definite knowledge of its size or nesting levels

Question

Traversing JSON data in a recursive manner without definite knowledge of its size or nesting levels

Currently, I'm working on a chrome app that utilizes local storage. The backend returns JSON data which I then save locally and encrypt all the items within the JSON. I have multiple sets of JSON with different encryption functions for each set.

I attempted to create a dynamic function that can return a copy of these JSON sets with each item encrypted, but I couldn't get it to work properly. My JSON includes both arrays and objects.

My question is, is it possible to create such a dynamic function? If yes, could someone provide me with a working sample?

Just so you know, I'm using angularJS and here is the code snippet I am currently working with:

// This function returns a copy of JSON with encrypted values.
fac.encryptData = function(param) {
    // Encryption logic goes here
};

In essence, I have separate functions for encrypting different JSON structures, and I want to consolidate them into a single dynamic function to handle encryption for various types of JSON data.

Here is a suggestion:

function encryptData(data) {
    var encryptedData = null;
    if (typeof data == 'object') {
        encryptedData = {};
        angular.forEach(data, function (value, key) {
            encryptedData[key] = encryptData(value);
        }
    } else if (data instanceof Array) {
        encryptedData = [];
        for (var i = 0; i < data.length; i++) {
            encryptedData.push(encryptData(data[i]));
        }
    } else {
        encryptedData = base64.encode(data.toString());
    }
    return encryptedData;
}
