Here’s a quick primer on upgrading your Classic ASP site Recaptcha V1 to V2.<\/p>\n

First, go to Google Recaptcha online and generate yourself a v2 pair of keys for your site’s domain.<\/p>\n

Next:<\/p>\n

On the page with the “FORM” on it on which you want to display the Recaptcha V2.<\/p>\n

Add to the HEADER (inside the HEAD TAGS):<\/strong><\/p>\n

<script src='https:\/\/www.google.com\/recaptcha\/api.js'><\/script><\/pre>\n
 <\/p>\n
Replace the existing code which renders your v1 recaptcha with this line:<\/strong><\/p>\n
<div class=\"g-recaptcha\" data-sitekey=\"put your google public v2 key here\" ><\/div><\/pre>\n
 <\/p>\n
on your FORM SUBMIT page (where the v2 form gets submitted to):<\/strong><\/p>\n
Inside ASP tags, place this line:<\/strong><\/p>\n
Response.LCID = 1033 ' USA LCID<\/pre>\n
It is a required element for the JSON Parser.<\/p>\n
Inside the HEAD:<\/strong><\/p>\n
<!--#include file=\"jsonObject.class.asp\" --><\/pre>\n
 <\/p>\n
you can get this file from my site HERE<\/a><\/p>\n
now the processing code to handle the Recaptcha JSON response:<\/p>\n
 <\/p>\n
If Request.ServerVariables(\"REQUEST_METHOD\") = \"POST\" Then\r\n\u00a0Dim recaptcha_secret, sendstring, objXML\r\n\u00a0\r\n\u00a0recaptcha_secret = \"your secret key goes here\"\r\n\r\n\u00a0sendstring = \"https:\/\/www.google.com\/recaptcha\/api\/siteverify?secret=\" & recaptcha_secret & \"&response=\" & Request.form(\"g-recaptcha-response\")\r\n\r\n\u00a0Set objXML = Server.CreateObject(\"MSXML2.ServerXMLHTTP\")\r\n\u00a0objXML.Open \"GET\", sendstring, False\r\n\r\n\u00a0objXML.Send\r\n\u00a0\r\n\u00a0set jsonObj = new JSONobject\r\n\u00a0set jsonArr = new jsonArray\r\n\r\n\r\n\u00a0jsonString = objXML.responseText\r\n\u00a0\r\n\u00a0set outputObj = jsonObj.parse(jsonString)\u00a0\u00a0\r\n\u00a0\r\n\u00a0\r\n\u00a0if jsonObj.value(\"success\") then\r\n\u00a0\u00a0Global_Msg=\"Captcha GOOD!\"\r\n\u00a0else\r\n\u00a0\u00a0Global_Msg=\"Invalid Recaptcha Response.\"\r\n\u00a0end if\r\n\u00a0\r\n\u00a0Set objXML = Nothing\r\nEnd If\r\n\r\nif Global_Msg<>\"Captcha GOOD!\" then\r\n%>\r\ninvalid RECAPTCHA response.\u00a0 Hit back and try again.\r\n<%\r\nresponse.end\r\n\r\nend if<\/pre>\n
