how to secure private info on palms

Archived from groups: comp.sys.palmtops (More info?)

Hi,

This is for a Treo 180. I am looking for an application that will:

1) encrypt and hide private documents five (or whatever) minutes after
the system shuts down.

2) Then, if I need the docs, I will have to explicitly show them.

I am currently evaluating teallock which does 1), but then
*automatically* decripts them after turning the unit back on which
renders it irresponsive while the decryption is going on.

Thanks,

Mirko
