How to Obfuscate Email on Your Website with JavaScript?

When you’re looking to protect your email address from spam bots and other malicious actors, one of the best ways to do so is by obfuscating it. By obscuring your email address, you make it much harder for these bad actors to find and abuse your information.

HOW TO OBFUSCATE EMAIL ON YOUR WEBSITE WITH JAVASCRIPT

One of the most common ways to obfuscate an email address is by using JavaScript. By using a few lines of code, you can make it so that your email address is only visible to humans and not to bots.

Let’s take a look at how you can obfuscate your email address with JavaScript.

The first thing you’ll need to do is create a function that will take your email address and output it in a way that is difficult for bots to read.

You can do this by using a series of characters that are not commonly used in email addresses, such as the number “1” instead of the letter “l”.

You can also use other symbols, such as the “@” symbol, to make your email address more difficult to read.

Once you have your function, you’ll need to use it to display your email address on your website. You can do this by using the “innerHTML” property of an HTML element.

For example, if you wanted to display your email address in a paragraph tag, you would use the following code:

<p id=”email”>my_email@domain.com</p>

<script>

function obfuscate(email) {

// your code here

}

document.getElementById(“email”).innerHTML = obfuscate(“my_email@domain.com”);

</script>

This code will output your email address as a series of characters that are difficult for bots to read. However, it will still be visible to humans who view the source code of your page.

If you want to take things a step further, you can use JavaScript to encrypt your email address. This will make it even more difficult for bots to read, but it will also make it more difficult for humans to read as well.

Encrypting your email address can be done with the “btoa” function. This function takes a string and outputs it as a base-64 encoded string.

For example, the following code will encrypt the email address “my_email@domain.com”:

<script>

function encrypt(email) {

return btoa(email);

}

document.getElementById(“email”).innerHTML = encrypt(“my_email@domain.com”);

</script>

This code will output your email address as a base-64 encoded string. This string will be difficult for both bots and humans to read.

If you want to make things even more secure, you can combine obfuscation and encryption. This will make it very difficult for anyone, bot or human, to read your email address.

To do this, you’ll need to first obfuscate your email address with the method described above. Once you have your obfuscated email address, you can then encrypt it with the “btoa” function.

For example, the following code will first obfuscate and then encrypt the email address “my_email@domain.com”:

<script>

function obfuscate(email) {

// your code here

}

function encrypt(email) {

return btoa(email);

}

document.getElementById(“email”).innerHTML = encrypt(obfuscate(“my_email@domain.com”));

</script>

This code will output your email address as an encrypted and obfuscated string. This string will be very difficult for anyone, bot or human, to read.

There are a few other methods you can use to obfuscate your email address. For example, you can use CSS to hide your email address from bots.

You can also use HTML entities to encode your email address. This will make it more difficult for bots to read, but it will still be visible to humans.

Finally, you can use a web service such as “Email Obfuscator” to obfuscate your email address. This service will take your email address and output it in a way that is difficult for bots to read.

Using one of these methods, or a combination of them will make it much more difficult for bots to find and read your email address. This will help to protect your privacy and prevent spam.
