what will replace info xHead ?

I have been very happy using for a number of years the info .xHead software for encrypting important data ( bank, credit card, registration info etc etc etc )

they were great with on going support and updates

now i have a small problem that i can not edit a category ( the window does not appear )

but they seem to have disappeared/ vanished ( no more website ) xheadsoftware.com

does any one have a solution of how to fix this problem

and does anyone have a suggestion for a software to replace info.xHead

that works well on a Mac ?

many thankyuuus
