I am trying to setup a PHP encrypt/decrypt system and...

[Mike Dunlop]

I am trying to implement a php mechanism that will use GNUPG to 
encode a password which will then be stored in a MySQL database. I 
don't quite understand the keys (public vs private), so I am 
wondering what is the most simple way to decode the password? Do I 
need a key for that?
NOTE: We have root access on our server and only the admin (me) needs 
decyption ability (end-users don't need decyption ability...)]

Any help is much appreciated.

Thanks
