php - PHP openssl_open 开封失败

Question

我一直在尝试在 PHP 中设置一个简单的 openssl_seal 和 openssl_open 脚本（8.0.8 是我安装的版本），我没有收到任何错误，但 openssl_open 总是返回 FALSE。

如果我做错了什么，谁能告诉我？

$algo = 'aes-256-gcm';
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length($algo));
$data = "Data to Seal";

$res = openssl_pkey_new(array(
    'digest_alg'        => 'sha256',
    'private_key_bits'  => 2048,
    'private_key_type'  => OPENSSL_KEYTYPE_RSA
));

openssl_pkey_export($res, $privkey); 
    
$pubkey = openssl_pkey_get_details($res);
$pubkey = $pubkey["key"];

openssl_seal($data, $sealed, $envelope, array($pubkey), $algo, $iv);

$openKey = openssl_pkey_get_private($privkey);

if (openssl_open($sealed, $open, $envelope[0], $openKey, $algo, $iv)) {
    echo "OPENED: ".$open;
} else {
    echo "Failed to open Data!";
}
