Detokenization Configuration

The TokenEx iFrame also allows you to securely display detokenized sensitive data on a web page, while keeping the webserver out of PCI scope. For example, a booking engine could enable their customers to view detokenized data in a web portal. Using the Detokenization iFrame to present detokenized data in a web page allows TokenEx to host the PCI or other sensitive data, while you maintain complete control over the other content on the page.

Generating the Authentication Key for the Detokenization Iframe

In order to generate the Authentication Key for the Detokenization Iframe, you will need to provide an existing token value in place of the tokenScheme required when generating the Authentication Key for the tokenization modes of the iFrame.

warning

The Authentication Key is only valid with a timestamp less than 20 seconds old.

Name	Type	Description
tokenExId	string	Your TokenEx ID
origin	string	The fully qualified Origin of your application
timestamp	string	The timestamp (UTC) when the hash is generated, in yyyyMMddHHmmss format
token	string	The existing token to be detokenized

Sample Code

TokenEx ID: 123456789
Origin: https://mysite.com
Timestamp: 20180109161437 (January 9th, 2018 4:14:37 PM UTC, formatted in yyyyMMddHHmmss format)
Token: 5454545454545454
Template: tokenExID|origin|timestamp|token
Concatenated String for generating HMAC: 123456789|https://mysite.com|20180109161437|5454545454545454

Using the Detokenize Iframe

JavaScript

//create the config object
var iframeConfig = {
  origin: "https://mysite.com",
  timestamp: "20200109161437",
  tokenExID: "123456789",
  authenticationKey: "QmFzZTY0KEhNQRNTSEEyNTYoIlRva2VuRXhJRHxPcmlnaW58VGltZXN0YW1wfFRva2VuU2NoZW1lKSk=",
  token: "5454545454545454",
};

//create a new instance of the detokenize iframe, and add the container ID and config object
var iframe = new TokenEx.DetokenizeIframe("tokenExIframeDiv", iframeConfig);

//calling the iframe's load function adds the iframe to the DOM.
iframe.load();
