openssl_spki_new - Generate a new signed public key and challenge
SYNOPSIS
string openssl_spki_new (resource &$privkey, string &$challenge, [int $algorithm])
DESCRIPTION
Generates a signed public key and challenge using specified hashing algorithm
PARAMETERS
o $privkey
-$privkey should be set to a private key that was previously generated by openssl_pkey_new(3) (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.
o $challenge
- The challenge associated to associate with the SPKAC
o $algorithm
- The digest algorithm. See openssl_get_md_method().
RETURN VALUES
Returns a signed public key and challenge string or NULL on failure.
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(3) 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:
