推荐答案

你可以使用 XOR （带随机密钥）和base64 / atob。

You could use a combination of XOR (w/ random key) and base64/atob.

虽然它不会停止专门用于刮擦论坛的机器人，但请参见下文。

<?php
$email = '<a href="mailto:[e-mail]">[e-mail]</a>';

function xor_email($str) {
    $key = mt_rand(1, 192);
    for ($i = 0; $i < strlen($str); $i++) {
        $str[$i] = chr(ord($str[$i]) ^ $key);
    }
    return $key.'.'.base64_encode($str);
}
$enc = xor_email($email);
?>

<e data-enc='<?= $enc ?>'/>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>

<script>
var decode = function(key, hash) {
    var salt = parseInt(key);
    var result = '';
    for (var i=0; i<hash.length; i++) {
        result += String.fromCharCode(salt ^ hash.charCodeAt(i));
    }
    return result;
}
$(document).find('e').each(function(){
    var data = $(this).data('enc').split(".");
    $(this).replaceWith(decode(data[0], atob(data[1])));
});
</script>

会生成以下内容。

<e data-enc='102.WgdGDhQDAFtECwcPChIJXAsHFA8HBBMUDQ0DUVAmAQsHDwpIBQkLRFgLBxQPBwQTFA0NA1FQJgELBw8KSAUJC1pJB1g='/>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>

<script>
var decode = function(key, hash) {
    var salt = parseInt(key);
    var result = '';
    for (var i=0; i<hash.length; i++) {
        result += String.fromCharCode(salt ^ hash.charCodeAt(i));
    }
    return result;
}
$(document).find('e').each(function(){
    var data = $(this).data('enc').split(".");
    $(this).replaceWith(decode(data[0], atob(data[1])));
});
</script>

从收割机的角度来看，一旦确定了保护方法，就可以轻松地抓取电子邮件，如下所示。因此，您不会幻想通过默默无闻的安全措施无法保护您免受定制的电子邮件机器人/刮刀/收割机的侵害。

From a harvesters point of view, once determined the method of protection one could easily scrape out the email as followed. Just so you're under no illusions that security through obscurity will not protect you from a custom-made email bot/scraper/harvester.

<?php
$html = '<e data-enc=\'102.WgdGDhQDAFtECwcPChIJXAsHFA8HBBMUDQ0DUVAmAQsHDwpIBQkLRFgLBxQPBwQTFA0NA1FQJgELBw8KSAUJC1pJB1g=\'/>

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>

<script>
var decode = function(key, hash) {
    var salt = parseInt(key);
    var result = \'\';
    for (var i=0; i<hash.length; i++) {
        result += String.fromCharCode(salt ^ hash.charCodeAt(i));
    }
    return result;
}
$(document).find(\'e\').each(function(){
    var data = $(this).data(\'enc\').split("-");
    $(this).replaceWith(decode(data[0], atob(data[1])));
});
</script>';

function xor_email($str, $key) {
    for ($i = 0; $i < strlen($str); $i++) {
        $str[$i] = chr(ord($str[$i]) ^ $key);
    }
    return $str;
}

$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html);

//
foreach ($doc->getElementsByTagName('e') as $e) {
    // parse out XORed string
    $enc = $e->getAttribute('data-enc');
    $enc = explode('.', $enc);
    $decoded = xor_email(base64_decode($enc[1]), $enc[0]);

    // parse out email
    $sub_doc = new DOMDocument();
    $sub_doc->loadHTML($decoded);
    foreach ($sub_doc->getElementsByTagName('a') as $a) {
        echo $a->nodeValue;
    }
}
