openssl_spki_new
(PHP 5 >= 5.6.0, PHP 7, PHP 8)
openssl_spki_new — Generate a new signed public key and challenge
Beschreibung
$private_key, string $challenge, int $digest_algo = OPENSSL_ALGO_MD5): string|falseGenerates a signed public key and challenge using specified hashing algorithm
Parameter-Liste
-
private_key -
private_keyshould 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
-
digest_algo -
The digest algorithm. See openssl_get_md_method().
Rückgabewerte
Returns a signed public key and challenge string or false on failure.
Fehler/Exceptions
Emits an E_WARNING level error if an unknown signature algorithm
is passed via the digest_algo parameter.
Changelog
| Version | Beschreibung |
|---|---|
| 8.0.0 |
private_key accepts an OpenSSLAsymmetricKey instance now;
previously, a Ressource of type OpenSSL key was accepted.

Beispiele
Beispiel #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";
}
?>
