openssl_spki_new — Generate a new signed public key and challenge
&$privkey
, string &$challenge
[, int $algorithm = 0
] )Generates a signed public key and challenge using specified hashing algorithm
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.
challengeThe challenge associated to associate with the SPKAC
algorithmThe digest algorithm. See openssl_get_md_method().
Returns a signed public key and challenge string or NULL on failure.
Emits an E_WARNING level error if an unknown signature algorithm
is passed via the algorithm parameter.
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:
