openssl_spki_new — Generate a new signed public key and challenge

설명

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

Generates a signed public key and challenge using specified hashing algorithm

인수

privkey: privkey should be set to a private key that was previously generated by openssl_pkey_new() (or otherwise obtained from the other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR.
challenge: The challenge associated to associate with the SPKAC
algorithm: The digest algorithm. See openssl_get_md_method().

반환값

Returns a signed public key and challenge string or NULL on failure.

오류/예외

Emits an E_WARNING level error if an unknown signature algorithm is passed via the algorithm parameter.

예제

Example #1 openssl_spki_new() example

Generate a new SPKAC with the default digest (MD5)


<?php
$pkey = openssl_pkey_new('secret password');
$spkac = openssl_spki_new($pkey, 'testing');

if ($spkac !== NULL) {
    echo $spkac;
} else {
    echo "SPKAC generation failed";
}
?>

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():
