Recaptcha V2 under classic ASP

Here’s a quick primer on upgrading your Classic ASP site Recaptcha V1 to V2.

First, go to Google Recaptcha online and generate yourself a v2 pair of keys for your site’s domain.


On the page with the “FORM” on it on which you want to display the Recaptcha V2.

Add to the HEADER (inside the HEAD TAGS):

<script src='https://www.google.com/recaptcha/api.js'></script>


Replace the existing code which renders your v1 recaptcha with this line:

<div class="g-recaptcha" data-sitekey="put your google public v2 key here" ></div>


on your FORM SUBMIT page (where the v2 form gets submitted to):

Inside ASP tags, place this line:

Response.LCID = 1033 ' USA LCID

It is a required element for the JSON Parser.

Inside the HEAD:

<!--#include file="jsonObject.class.asp" -->


you can get this file from my site HERE

now the processing code to handle the Recaptcha JSON response:


If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
 Dim recaptcha_secret, sendstring, objXML
 recaptcha_secret = "your secret key goes here"

 sendstring = "https://www.google.com/recaptcha/api/siteverify?secret=" & recaptcha_secret & "&response=" & Request.form("g-recaptcha-response")

 Set objXML = Server.CreateObject("MSXML2.ServerXMLHTTP")
 objXML.Open "GET", sendstring, False

 set jsonObj = new JSONobject
 set jsonArr = new jsonArray

 jsonString = objXML.responseText
 set outputObj = jsonObj.parse(jsonString)  
 if jsonObj.value("success") then
  Global_Msg="Captcha GOOD!"
  Global_Msg="Invalid Recaptcha Response."
 end if
 Set objXML = Nothing
End If

if Global_Msg<>"Captcha GOOD!" then
invalid RECAPTCHA response.  Hit back and try again.

end if


For your convenience, here is all the code inside one ZIP file.

Slow rendering or display of CKFINDER directories

Have you installed CKFINDER (maybe on Classic ASP) and have a problem with very slow directory displays while the circular “wait” animation plays and eventually displays the directory?

Easy fix:

Within the config.asp file (located in the CKFINDER directory) while using the Classic ASP version of CKFINDER…

comment out this line

Images.Add “component”, “Auto”

just put an apostrophe in front of it like this (below)

‘ Images.Add “component”, “Auto”

Save your changes.  Refresh and reload CKFINDER and the directories should display instantly.
