我想在 php 中解析 X.509 证书。

该证书采用 DER 编码的 X.509 格式。

我尝试openssl_x509_parse method在 php 中使用，但它不起作用。证书数据是在 mdm 中为 CertificateList 触发命令后收到的有效数据。

我正在使用以下代码：

那么您的证书缺少 PEM 附件。如果您将这些BEGIN CERTIFICATE和END CERTIFICATE标记添加到您的证书中，它应该可以工作：

<?php
$data = // ... your certificate

// Add the missing PEM-enclosing
$x509Data =
      "-----BEGIN CERTIFICATE-----\n"
    . $data
    . "\n-----END CERTIFICATE-----";

// this is the same but I've added "print_r" so it is nicely formated
$fp = fopen('cert.txt','w+');
fwrite($fp, 'data=>'.print_r(openssl_x509_parse($x509Data,true), true));
fclose($fp);

phpseclib 是一个纯 PHP X.509 解析器，可以处理您的字符串，而无需将其封装在任何东西中。例如。

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

$x509 = new File_X509();
$cert = $x509->loadX509('MIIDizCCAnMCCQDCpCAUbA2P4TANBgkqhkiG9w0BAQUFADBrMSIw

print_r($cert);
?>

它总体上也更加通用。与OpenSSL 一样，要求每行长度为 64 个字符且不再需要。phpseclib otoh 不在乎。
