Hello @AllenTs2 ,
I can propose the following two methods, and you can choose any one of the below based on the flexibility and compatibility.
………
Method 1:
Hashing at the dataLayer level hashes the email before it is actually sent to Adobe Data collection, and improves the privacy and security of the data.
Step 1: Include the CryptoJS library in your HTML, which can be from the CDN URL. Below example is:
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.1.1/crypto-js.min.js"></script>
Step 2: Modify the current dataLayer push to include hashing the email with CryptoJS:
<script>
function hashEmail(email) {
return CryptoJS.SHA256(email).toString();
}
// Example code to collect email
var userEmail = “test1@gmail.com”;
dataLayer.push({
event: “pageLoad”,
user: {
email: hashEmail(userEmail),
authenticatedState: “Authenticated”
}
});
</script>
Method 2:
If you cannot change the website code, or if you prefer to keep data transformation in Adobe Data Collection, you can use a custom code data element to hash the email.
Step 1: Ensure CryptoJS is available in Adobe Data Collection. You can include it through a custom HTML tag.
Step 2: Create a new Data Element in Adobe Data collection.
Navigate to the Data Elements section and click "Add Data Element."
Select "Custom Code" under the type options. Enter the following code in the editor:
(function() {
var userEmail = _satellite.getVar('Email'); // Retrieve the email using another Data Element
return CryptoJS.SHA256(userEmail).toString();
})();
Name the Data Element something like “Hashed Email” and save.
Note: I have just used CryptoJS in the above examples. You can use any encryption library as per your convenience.
