Question

我已经浏览了Eric Vyncke的PHP dkim script，并复制了他为电子邮件中设置的DKIM标题做哈希的方式

   [value[0,0] for value in d.values()]

将被用作：

$DKIM_bh = base64_encode(pack('H*', sha1($body)));

然而，当我validate the email message它告诉我哈希不匹配时。

'bh='.$DKIM_bh.';'//...

我不确定我错过了什么？如何正确哈希主体和标题，以便我可以正确设置标题的DKIM值？

以下是如何使用dkim和php mail（）函数发送电子邮件的示例函数：

适用于Gmail.com和带附件的多部分/混合消息！

<?php
// Send simple email without DKIM SIgning
// YOUR E-MAIL
$name = 'Name Jony';
$sender = 'sdsdso@domain.pl';
$to = 'ffffu@gmail.com';
$subject = 'Simple html message with dkim';

$headers =
'MIME-Version: 1.0
From: "'.$name.'" <'.$sender.'>
Content-type: text/html; charset=utf8';

$message =
'<html>
    <header></header>
    <body>
        Hello, this a DKIM test e-mail
    </body>
</html>';

// NOW YOU WILL DO (after setting up the config file and your DNS records) :
// Make sure linefeeds are in CRLF format - it is essential for signing
$message = preg_replace('/(?<!\r)\n/', "\r\n", $message);
$headers = preg_replace('/(?<!\r)\n/', "\r\n", $headers);

require_once 'mail-signature.class.php';
require_once 'mail-signature.config.php';

$signature = new mail_signature(
    MAIL_RSA_PRIV,
    MAIL_RSA_PASSPHRASE,
    MAIL_DOMAIN,
    MAIL_SELECTOR
);
$signed_headers = $signature -> get_signed_headers($to, $subject, $message, $headers);

// Send email
ini_set('sendmail_from', $sender);
echo mail($to, $subject, $message, $signed_headers.$headers);
die();

如何使用PHP为dkim正确地散列正文和标题？
