Decode/Decrypt string using jQuery or JavaScript that was originally encoded in C#

I have a string that is encoded/encrypted using the following C# code:

public static string Encode(string text)
    {
        if (!Enabled)
            return text;

        return "~/Enc/" + System.Convert.ToBase64String(
                            System.Text.ASCIIEncoding.ASCII.GetBytes(text));
    }

How can I decode/decrypt it on the client side and get the original string before it was encoded/encrypted?

I've already tried atob(encodedString) and it doesn't return the original value.

you could always pass the client Url as a parameter in the viewmodel - ie.

 public sting AjaxUrl {get;set;}

etc. ,then in model in the javascript

 var link = '@Model.AjaxUrl'

(This may defeat the purpose of encryping the link though.)

atob works fine if all you're doing is base-64 encoding something.

You're not, though.

atob isn't going to work because you wouldn't be getting the encoded string, you'd be getting ascii bytes of the string + the "~/Enc" text you're placing before it.
