在 PHP 服务器上签署 .mobileconfig

谁能告诉我如何使用openssl smime -sign -signer cert.pem -inkey key.pem -certfile ca-bundle.pem -nodetach -outform der -in profile-uns.mobileconfig -out profile-sig.mobileconfigPHP 中的这个（这个工作正常！）？

I tried

$path = __DIR__ . DIRECTORY_SEPARATOR;  // my actual directory
$infilename = $path . 'profile.mobileconfig'; // my unsigned profile
$outfilename = $path . 'profile-sig.mobileconfig'; // my signed profile
$signcert = file_get_contents($path . 'cert.pem'); // my certificate to sign
$privkey = file_get_contents($path . 'key.pem'); // my private key of the certificate
$extracerts = $path . 'ca-bundle.pem'; // the cert chain of my CA

echo openssl_pkcs7_sign($infilename, $outfilename , $signcert, $privkey, array(), PKCS7_NOATTR,$extracerts);

没有成功。我还尝试了所有 PKCS7 属性...

Calling openssl smime with exec工作正常：

exec('openssl smime -sign -signer cert.pem -inkey key.pem -certfile ca-bundle.pem -nodetach -outform der -in profile.mobileconfig -out profile-sig.mobileconfig');
