Description:
------------
openssl_seal always returns FALSE 

Returned sealed data and envelope keys are empty. 

There is no error returned by openssl_error_string

I also tried various certificates and key lengths.

config: 

php4.3.10 / openssl OpenSSL 0.9.7e / on BSD/OS 4.2 i386

'./configure' '--with-mysql' '--enable-ftp' '--enable-dbase' '--with-gd' '--enable-gd' '--with-apxs=/web/bin/apxs' '--with-openssl=/usr/local/ssl' '--with-zlib-dir=/usr/local' '--enable-curl' '--with-curl=/usr/local' '--enable-mhash' '--with-mhas=/usr/local'

The another config: '--with-openssl' , also produces this bug.

The same script runs ok on another computers (php4.3.9/macosx or php4.3.10/linux)



Reproduce code:
---------------
<?php
	
function seal($info,$key){

  if($pk = openssl_get_publickey($key)){
    echo openssl_error_string();echo '<br>';

    $res=openssl_seal($info, $sealed, $ekeys, array($pk));
    echo openssl_error_string();echo '<br>';
    var_dump($res);echo '<br>';

    openssl_free_key($pk);	
			
    return array('sealed'=>$sealed,'ekey'=>$ekeys[0]);
  }
  echo openssl_error_string();echo '<br>';
  return FALSE;
}

";

print_r(seal("Secret data",$key));echo '<br>';
?>


Expected result:
----------------
int(11)
Array ( [sealed] => ...here goes the encrypted string in binary ... [ekey] => ..here goes the envelope key in binary ...)

Actual result:
--------------
bool(false)
Array ( [sealed] => [ekey] => )
