Neos MailObfuscator

In order to make life for spammers more difficult, this package provides an obfuscation of email addresses. The email address is obfuscated by a rot13 like algorithm with random offsets.

When the link is clicked, the email address is unobfuscated by the same algorithm in JavaScript:

<a href="mailto:[email protected]">[email protected]</a>

will become

<a href="javascript:linkTo_UnCryptMailto('obfuscatedEmail', -randomNumber)">foo (at) example.com</a>

The replacement is done in 2 steps, thus it is possible to have a link label that is different from the email address:

<a href="mailto:[email protected]">Contact us</a>

will become

<a href="javascript:linkTo_UnCryptMailto('obfuscatedEmail', -randomNumber)">Contact us</a>

Installation

Install the composer package in your site package or distribution:

$ composer require networkteam/neos-mailobfuscator

There is no need for configuration, as a Fusion processor is attached to body of Neos.Neos:Page. That means, that the complete content of body tag is obfuscated.

Compatibility

See the following table for the correct plugin version to choose:

Neos CMS Plugin version
>= 3.0 2.x
< 3.0 1.x

Configuration

Obfuscation can be disabled for specific node types by unsetting the processor:

prototype(Neos.Neos:Page) {
    @process.networkteamNeosMailObfuscator >
}

The JavaScript include can be disabled for custom minification:

prototype(Neos.Neos:Page) {
    networkteamNeosMailObfuscator >
}

The replacement string for the at-sign (@) can be configured. It will be inserted as HTML without escaping, so it's possible to replace it with something like an image:

# Settings.yaml
Networkteam:
  Neos:
    MailObfuscator:
      atCharReplacementString: '<img src="https://example.com/at-icon.png" alt="at" />'
