Question

Inspired by http://devzone.zend.com/1278/using-gnupg-with-php/ and with help @ PHP ASCII Armored PGP encrypted string

I was able to GnuPG-encrypt a string with a 3rd party public key when running in CLI.

• set GNUPGHOME to world-readable location
• chmod keyring files to 666
• cli php encrypts the string just fine

PHP 5.2.10 (cli) (built: Nov 13 2009 11:44:05)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies

but…

I get “exit signal Segmentation fault (11)” when invoking addencryptkey running the same script through the webserver (Apache on CentOS).

apache errorl log

[notice] child pid 30682 exit signal Segmentation fault (11)

nothing of value in syslog…

any pointers? thanks!

code (nothing earth shattering):

// GnuPG code
putenv("GNUPGHOME=/opt/.gnupg/");

$gpg = new gnupg();
$gpg->seterrormode(gnupg::ERROR_EXCEPTION); 
$gpg -> setarmor(1);

try 
{
    $info = $gpg -> addencryptkey("KEY");
    var_dump($info);
    $enc = $gpg -> encrypt($token);
    var_dump($enc);
} 
catch (Exception $e) {
    echo 'ERROR: ' . $e->getMessage();
}

Answer 1

oh well – my fault – as soon as I did

chmod -R 777 

on my GNUPGHOME – it all worked

thought it was happy with 666 (and CLI was happy with just rw)
