openssl_spki_new

(PHP 5 >= 5.6.0, PHP 7, PHP 8)

openssl_spki_new — Generate a new signed public key and challenge

Beschreibung

openssl_spki_new(OpenSSLAsymmetricKey $private_key, string $challenge, int $digest_algo = OPENSSL_ALGO_MD5): string|false

Generates a signed public key and challenge using specified hashing algorithm

Parameter-Liste

private_key: private_key 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
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";
}
?>

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():
