[cobalt-users] [RaQ4] PHP/Gnupg question

["Andy Clyde, oxfordmusic.net" <cobalt-users@xxxxxxxxxxxxxxx>]

i have just installed Gnupg on the request of a client. this client wants to
use a combination of Gnupg and PHP to send secure emails.
in my PHP setup, i turned Safe_Mode on as there are multiple domains on the
server. obviously shell_exec won't work with safe mode on but i read on the
PHP site that you can use exec with safe mode if you copy the program
required to a special safe_mode_exec _dir.
my question is: can i create a php_exec directory and just copy gpg into it?
will gpg work like this? or will this break gpg?

TIA

andy
