Description:
------------
---
From manual page: http://www.php.net/function.openssl-pkey-new#refsect1-function.openssl-pkey-new-description
---

The resulting resource cannot be used with openssl_pkey_get_public as stated.

At least not always.

Maybe that statement is only valid for some inputs for the config?

If so, clarification is needed, preferably identifying the sorts of keys where the statement is applicable.

See also: 25614 from 2009...


Test script:
---------------
$key_pair = openssl_pkey_new(array('digest_alg'=>'sha1', 'private_key_bits'=>1024, 'private_key_type'=>OPENSSL_KEYTYPE_RSA));

var_dump($key_pair);

$public = openssl_pkey_get_public($key_pair);
var_dump($public);


Expected result:
----------------
resource (4) of type (OpenSSL key)


Actual result:
--------------
PHP Warning:  openssl_pkey_get_public(): Don't know how to get public key from this private key in /var/www/vhost.d/zackstrade.dev/ib/keys/key_setup.php on line 8

The handling of bug #25614 was really suboptimal.  Despite the
last few comments, the documentation is still in error (see the
first comment from wez).
