Hi,
load for update (and using WriteUpdate()) means that you keep the file
as is and only add your changes at the end. Having new values encrypted
and old values not, or using different encryption method, or even
trying to use old encryption on the new content, doesn't sound right to
me.
Doing sign & encrypt at the same time sounds the way to go, as you
figured out yourself.
Bye,
zyx
