yii2-email-obfuscator

Email obfuscatior plugin for Yii2., _(*1)

This plugin combines some Email obfuscation technics., _(*2)

The @ char is removed and only its index is passed on. It will be reinserted using the expression String.fromCharCode(422*4).
The address itself will be transmitted as a ROT13 transformed string which will be retransformed by Javascript.
The "mailto:" prefix is decoded as a reversed string which gets unreversed by Javascript.

The Email address "mail@example.com" will result in the following code:, _(*3)

<script type="text/javascript">
var action=":otliam".split("").reverse().join("");
var href="znvyrknzcyr.pbz".replace(/[a-zA-Z]/g, function(c){return String.fromCharCode((c<="Z"?90:122)>=(c=c.charCodeAt(0)+13)?c:c-26);});
href=href.substr(0, 4) + String.fromCharCode(4*2*2*4) + href.substr(4);
var a = "<a href=\""+action+href+"\">"+href+"</a>";
document.write(a);
</script>
