如何正确使用PHP为dkim散列正文和标题？ [英] How to properly hash body and headers with PHP for dkim?
问题描述
我已经浏览了Eric Vyncke的PHP dkim脚本并复制了他为电子邮件中设置的DKIM标头设置了哈希值。
$ pre $ $ DKIM_bh = base64_encode（pack（'H *'，sha1（$ body）））;
可以这样使用：
'bh ='。$ DKIM_bh。';'// ...
然而，当我验证电子邮件时，它告诉我该散列没有'
$ headers。='DKIM-Signature：v = 1; A = RSA-SHA1; C =轻松/简单; Q = DNS / TXT; bh ='; // ...
$ body ='测试PHP + SMTP认证邮件，3。';
bh ='。base64_encode（pack（'H *'，sha1（$ body）））。';'; // ...
我不确定我错过了什么？ 以下是使用dkim和php mail（）函数发送电子邮件的示例函数： https://github.com/breakermind/PHP-DKIM 适用于Gmail.com和多部分/带有附件的混合信息！ I've gone through Eric Vyncke's PHP dkim script and copied how he was doing hashes for DKIM headers set in emails Would be used as so: However when I validate the email message it tells me that the hash doesn't match. I'm not sure what I'm missing? How do I properly hash the body and headers so I can set the DKIM values for the header properly? Here is example functions how to send emails with dkim and php mail() function: https://github.com/breakermind/PHP-DKIM Works on Gmail.com and multipart/mixed messages with attachments!
