openssl_spki_new

(PHP 5 >= 5.6.0, PHP 7)

openssl_spki_new生成一个新的签名公钥和挑战

说明

string openssl_spki_new ( resource &$privkey , string &$challenge [, int $algorithm = 0 ] )

使用指定的哈希算法生成一个新的签名公钥和挑战。

参数

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。

返回值

成功,返回一个签名的公钥和挑战,失败返回 NULL .

错误/异常

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。

范例

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:

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():
