Summary: OpenSSL: signing function for spkac
Status: Feedback
Type: Feature/Change Request
Package: OpenSSL related
Operating System: Irrilevant
PHP Version: trunk
Block user comment: N
Private report: N
New Comment:
One other question about using SPKAC's when creating a x509. It seems the
current method using openssl_csr_new() which in turn calls the
php_openssl_make_REQ() to assign the specified DN attributes has no method of
adding the SPKAC field.
After digging around it seems logical to use the OBJ_create() and OBJ_* family
of functions to add NID. Please forgive me if I am way off here but any
direction you could point me in using the existing functions to output and sign
a certificate similar to the following command?
openssl ca -config /path/to/openssl.conf -days 180 -notext -batch \
-spkac /path/to/cert.pem -out /path/to/signed.pem -passin pass:'random'
My assumption is that I will need to create one specifically for this purpose
but would like your insight.

This will test all five new functions unless you would like one test case per
function?
--TEST--
openssl_spki_new(), openssl_spki_verify(), openssl_spki_export(),
openssl_spki_export_challenge(), openssl_spki_details()
--SKIPIF--
<?php
if (!extension_loaded("openssl")) die("skip");
if (!@openssl_pkey_new()) die("skip cannot create private key");
?>
--FILE--
<?php
echo "Creating private key\n";
$key = openssl_pkey_new();
if ($key === false)
die("failed to create private key\n");
echo "Creating new SPKAC\n";
if (!function_exists("openssl_spki_new"))
die("openssl_spki_new() does not exist\n");
$spki = openssl_spki_new($key, "sample_challenge_string");
if ($spki === false)
die("could not create spkac\n");
echo "Verifying SPKAC\n";
if (!function_exists("openssl_spki_verify"))
die("openssl_spki_verify() does not exist\n");
$x = openssl_spki_verify(preg_replace("/SPKAC=/", "", $spki));
if ($x === false)
die("could not verify spkac\n");
echo "Exporting challenge\n";
if (!function_exists("openssl_spki_export_challenge"))
die("openssl_spki_export_challenge() does not exist\n");
$y = openssl_spki_export_challenge(preg_replace("/SPKAC=/", "", $spki));
if ($y !== "sample_challenge_string")
die("could not verify challenge string from spkac\n");
echo "Exporting public key from SPKAC\n";
if (!function_exists("openssl_spki_export"))
die("openssl_spki_export() does not exist\n");
$z = openssl_spki_export(preg_replace("/SPKAC=/", '', $spki));
if ($z === "")
die("could not export public key from spkac\n");
echo "Generating details of SPKAC structure\n";
if (!function_exists("openssl_spki_details"))
die("openssl_spki_details() does not exist\n");
$w = openssl_spki_details(preg_replace('/SPKAC=/', '', $spki));
if ($w === "")
die("could not obtain details from spkac\n");
echo "OK!\n";
openssl_free_key($key);
?>
--EXPECT--
Creating private key
Creating new SPKAC
Verifying SPKAC
Exporting challenge
Exporting public key from SPKAC
Generating details of SPKAC structure
OK!

Please see the phpt files in ext/openssl/tests/
this is how tests should be written.
Further explanations are available here: http://qa.php.net/
Thanks!

Hi!
Thanks for the patch, please add some test cases as well (phpt format) so we
can
easily valid the new functions.
Also be sure that the patched ssl can still be built against older openssl
version
as we still support them (0.9.x serie for trunk and 5.4).

Since I have not seen any changes on this I am going to post the patch to php-
internals list.
