Question

Encoding an URL with btoa and atob

Forms

Updated December 14, 2017

asked on December 5, 2017

Good afternoon,

I'm working on a project in which I'd like to encode a URL coming from a Workflow email to look something like:

https://myurl.com?encode=dGVzdA==

and then I'd be doing the decoding from the form. The form does not have to be as secure, it's just for mormatting purposes that I don't want the actual information in the URL.

Problem is that I don't know how to decode it when coming from Workflow. I don't want to create additional hidden fields just to encode the parts that I need.

Any ideas or suggestions?

Thank you,

Raul Gonzalez

So the way id do this is use the SDK Script activity with the following code.

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using System.Net;


    public class Script1 : RAScriptClass100
    {
        /// <summary>
        /// 64 bit encode method
        /// </summary>
        ///
        static public string EncodeTo64(string toEncode) {
            byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
            string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);
            return returnValue;
        }

        protected override void Execute()
        {
            string baseVal = GetTokenValue("baseValue").ToString();
            string encodeVal = EncodeTo64(baseVal);
            SetTokenValue("encodeValue",WebUtility.UrlEncode(encodeVal));
        }
    }

To make this work create 2 tokens called baseValue and encodeValue. Add the value you want to encode into baseValue then call the SDK activity.

What method are you using to encrypt the parameters, its pretty easy to write a decryption algorithm in JavaScript that pulls the parameter value from the url.

Thanks Aaron,

For the decryption part I was thinking in using the example as shown below, I just can't think of a way to encrypt it coming from the Workflow.

The workflow sends out an email using an Email Activity that says:

URL: http://www.something.com?parameter=test

I want for it to send it like:

URL: URL: http://www.something.com?parameter=dGVzdA==

and I can do the decription in the form. Again, this is not for anything secure, it's just to keep things in a certain format.

$( document ).ready(function() {

  alert(btoa("test"));
  
  alert(atob('dGVzdA=='));
  
});

Aaron,

We are delaying the part of the project for which I wanted to use the encoding so I wasn't able to fully try it. Thanks for sharing and I'll give your code a try as soon as I get back into that piece of the project.

Thanks again,

Raul Gonzalez
