openssl_spki_new
(PHP 5 >= 5.6.0, PHP 7)
openssl_spki_new — Generate a new signed public key and challenge
Description
&$privkey
, string &$challenge
[, int $algorithm = 0
] ) : stringGenerates a signed public key and challenge using specified hashing algorithm
Parameters
-
privkey -
privkeyshould 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().
Errors/Exceptions
Emits an E_WARNING level error if an unknown signature algorithm
is passed via the algorithm parameter.
Examples
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 above example will output something similar to:
