Hi
There is experimental extension for gnupg for php:
http://es2.php.net/manual/en/ref.gnupg.php http://pecl.php.net/package/gnupg
I dont know if its a good idea implement experimental extension, but it would work on more installations instead of using exec()
There is also a JS only implementation of the GnuPG encryption scheme available at http://www.hanewin.net/encrypt/. I haven't played with it but if it really works it's a safe solution. The problems are performance and that attachments will not be encrypted.
