openssl ext sm2 compatibility

Description

The following code:

<?php
$public_key = openssl_pkey_get_public(file_get_contents('sm2pubkey.pem'));
$d1 = openssl_pkey_get_details($public_key);
var_dump($d1);

Resulted in this output:

  ["dh"]=>
  array(1) {
    ["p"]=> 
  }
  ["type"]=>
  int(2)

But I expected this output instead:

  ["ec"]=>
  array(5) {
    ["curve_name"]=>
    string(9) "sm2"
    ["curve_oid"]=>
    ["x"]=> 
    ["y"]=> 
    ["d"]=> 
  }
  ["type"]=> int(3)

the sm2pubkey.pem generate command

Operating System

Ubuntu 22.04.1 LTS

使用 PHP 8.1.2、OpenSSL 3.0.2 以及提供的 openssl ecparam 和 openssl ec 命令复现该报告。从 openssl_pkey_get_public() 和 openssl_pkey_get_details() 入口点开始，然后将返回的结构与预期的 SM2 EC 详细信息进行比较。当 SM2 公钥被报告为具有预期曲线信息的 EC 密钥时，即表示完成。
