php - 为什么 phpseclib 生成不兼容的证书？

Question

为什么当我尝试使用从 phpseclib 生成的证书/ key 对时，OpenSSL 服务器代码会出错？从 OpenSSL 生成的证书/ key 工作正常。我该如何解决这个问题？

直接取自 phpseclib documentation 的证书/ key 生成:

<?php
include('File/X509.php');
include('Crypt/RSA.php');

// create private key / x.509 cert for stunnel / website
$privKey = new Crypt_RSA();
extract($privKey->createKey());
$privKey->loadKey($privatekey);

$pubKey = new Crypt_RSA();
$pubKey->loadKey($publickey);
$pubKey->setPublicKey();

$subject = new File_X509();
$subject->setDNProp('id-at-organizationName', 'phpseclib demo cert');
//$subject->removeDNProp('id-at-organizationName');
$subject->setPublicKey($pubKey);

$issuer = new File_X509();
$issuer->setPrivateKey($privKey);
$issuer->setDN($subject->getDN());

$x509 = new File_X509();
//$x509->setStartDate('-1 month'); // default: now
//$x509->setEndDate('+1 year'); // default: +1 year

$result = $x509->sign($issuer, $subject);
echo "the stunnel.pem contents are as follows:\r\n\r\n";
echo $privKey->getPrivateKey();
echo "\r\n";
echo $x509->saveX509($result);
echo "\r\n";
?>

Phpseclib 要求您调用 $x509->setSerialNumber("0") 否则它将生成无效的证书。
