从 MIME 创建 S/MIME？
我不完全理解，如果有一些文档或帮助，我们将不胜感激:)
使用 PHP，我通过使用 ezcomponents Mail 对象创建一个 MIME。但我不明白的是：
您是否通过使用 openssl_pkcs7_sign ?或者您从头开始创建 S/MIME 并在完成后对其进行签名？
当我尝试理解正确的做事方式时，请耐心等待。
编辑：找到这段代码可以更好地说明我的问题
<?
// Setup mail headers.
$headers = array("To" => "[email protected]",
"From" => "[email protected]",
"Subject" => "A signed and encrypted message.");
// Sign the message first
openssl_pkcs7_sign("msg.txt","signed.txt",
"signing_cert.pem",array("private_key.pem",
"password"),array());
// Get the public key certificate.
$pubkey = file_get_contents("cert.pem");
//encrypt the message, now put in the headers.
openssl_pkcs7_encrypt("signed.txt", "enc.txt",
$pubkey,$headers,0,1);
$data = file_get_contents("enc.txt");
// separate header and body, to use with mail function
// unfortunate but required, else we have two sets of headers
// and the email client doesn't decode the attachment
$parts = explode("\n\n", $data, 2);
// send mail (headers in the Headers parameter will override those
// generated for the To & Subject parameters)
mail($mail, $subject, $parts[1], $parts[0]);
?>
I don't completely understand and some documentation or help would be appreciated greatly :)
Using PHP I create a MIME by using ezcomponents Mail object. But what I do not understand is:
Do you create an S/MIME message from a original MIME by signing it with openssl_pkcs7_sign ? or do you create an S/MIME from scratch and sign it when its done?
Please bear with me as I try to understand the correct way of doing things.
EDIT: Found this piece of code to illustrate my question better
<?
// Setup mail headers.
$headers = array("To" => "[email protected]",
"From" => "[email protected]",
"Subject" => "A signed and encrypted message.");
// Sign the message first
openssl_pkcs7_sign("msg.txt","signed.txt",
"signing_cert.pem",array("private_key.pem",
"password"),array());
// Get the public key certificate.
$pubkey = file_get_contents("cert.pem");
//encrypt the message, now put in the headers.
openssl_pkcs7_encrypt("signed.txt", "enc.txt",
$pubkey,$headers,0,1);
$data = file_get_contents("enc.txt");
// separate header and body, to use with mail function
// unfortunate but required, else we have two sets of headers
// and the email client doesn't decode the attachment
$parts = explode("\n\n", $data, 2);
// send mail (headers in the Headers parameter will override those
// generated for the To & Subject parameters)
mail($mail, $subject, $parts[1], $parts[0]);
?>
