How can we encrypt http get query parameters before sending to another site?

Question

I am sending a http get request from server side to another site. How can I encrypt all data before sending the request? How can I decrypt the parameters in the second site to read them back? What encryption do we generally use for this?

var response = HttpContext.Current.Response;
response.Redirect(string.Format("http://localhost:58372/Testsite?type={0}&requestxml={1}", type, requestXML));

Don't do HTTP GET but HTTP POST via SSL instead. Put the sensitive data into the body payload, not into the URL. — Uwe Keim, May 19 '19 at 15:13

Convert the parameters into base64 encode / decode. Make sure u convert your all parameters to string.

Encode

 var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(stringtoencode);
  return System.Convert.ToBase64String(plainTextBytes);

Decode

  var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
  return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
