Thanks for all the welcomes.
OK, I ran PHP Info and found mcrypt is there as an installed extension (Thanks again for great hosting)
I understand that I need to set a whole bunch of items for this type of encrytion($key, $cipher_alg, etc) so Ill let you know how I go.
I may even add a tutorial of how to do this to your forums so you can check Ive done it right an others can use it.
Thanks
