The usage of openssl_pkey_new() in the example above is wrong.
openssl_pkey_new() requires an array as first parameter
Working example for openssl_pkey_new():
http://php.net/manual/de/function.openssl-pkey-new.php#111769
(PHP 5 >= 5.6.0, PHP 7, PHP 8)
openssl_spki_new — 生成一个新的签名公钥和挑战
&$privkey
, string &$challenge
, int $algorithm = 0
) : string使用指定的哈希算法生成一个新的签名公钥和挑战。
privkey
privkey 应该被设置为由openssl_pkey_new()函数预先生成(或者以其他方式从openssl_pkey函数集中获得)的私钥。该密钥的相应公共部分将用于签署CSR.
challenge与SPKAC有关的挑战。
algorithm摘要算法。参见 openssl_get_md_method()函数。
成功，返回一个签名的公钥和挑战，失败返回 NULL .
如果 algorithm 参数是一个未知的签名算法，将会抛出一个 E_WARNING 级的错误。
Example #1 openssl_spki_new() 范例：
使用默认的摘要算法(MD5)生成一个新的SPKAC
<?php
$pkey = openssl_pkey_new('secret password');
$spkac = openssl_spki_new($pkey, 'testing');
if ($spkac !== NULL) {
echo $spkac;
} else {
echo "SPKAC generation failed";
}
?>
以上例程的输出类似于：
