【问题描述】：

有什么方法可以用 pear Mail 发送数字签名的电子邮件吗？

我盗用了这段代码，但它没有运行。

    <?php
    require_once("Mail.php");
    require_once('Mail\mime.php');

    $recipients = "[e-mail]";

    $headers["From"] = "[e-mail]";
    $headers["To"]      = $recipients;
    $headers["Subject"] = "Zkouska";

    $params["host"] = "mail.xxx.cz";
    $params["username"] = "[e-mail]";
    $params["password"] = "xxx";

    $body = "Zkouska Spojeni !";

    $mime = new Mail_mime();

    $fp = fopen("./msg.txt", "w");
    fwrite($fp, $body );
    fclose($fp);

    echo "Sending mail:\n";
    echo "Headers:\n" . print_r($headers);
    echo "\n\nBody:\n$body";
    echo "\n---END OF MAIL BODY---\n";

    openssl_pkcs7_sign("C:/data/www/msg.txt", "C:/data/www/signed.txt", "file://C:/data/www/04.pem", "file://C:/data/www/newkey.pem", $headers);

    $data = file_get_contents("C:/data/www/signed.txt");

    $mime->setTXTBody($data);

    $body = $mime->get();
    $headers = $mime->headers($headers);

    $headers["Content-Type"] = "Multipart/signed; protocol=\"application/pkcs7-signature\"; micalg=sha1; boundary=\"------------ms070206070302000302000502\"";

    $mail_object =& Mail::factory("smtp", $params);
    $mail_object->send($recipients, $headers, $body);
    echo "Email sent";


    ?>

有人可以给我建议如何解决这个问题吗？谢谢。

** 我在互联网解决方案上找到了，在那里人们可以使用 openssl_pkcs7_sign 函数在文件中生成签名的电子邮件。我已经生成了这个文件，但我不知道如何为 $mail_object->send 函数 args 解析这个文件。特别是我不知道如何构造 headers 数组

感谢您的帮助

【问题讨论】：

您两次发布代码是否有原因。这是你想要运行的吗？

当然不是，重复代码已经修复。

为 PEAR 的使用点赞！

【参考方案1】：

openssl_pkcs7_sign("C:/data/www/msg.txt", "C:/data/www/signed.txt", "file://C:/data/www/04.pem", "file://C:/data/www/newkey.pem", $标头）；

我觉得你应该试试：

openssl_pkcs7_sign("C:/data/www/msg.txt", 
                   "C:/data/www/signed.txt", 
                   "file://C:/data/www/04.pem", 
                   array("file://C:/data/www/newkey.pem","CRT pass"), 
                   $headers);

并发送标头参数：

$data = file_get_contents("C:/data/www/signed.txt");
$parts = explode("\n\n", $data, 2);

// with mail() function you should
mail($to, $subject, $parts[1], $parts[0]);

// I suppose in the same way for Pear Mail
$mail_object =& Mail::factory("smtp", $params);
$mail_object->send($recipients, $parts[0], $parts[1]);
