I do have a separate stack built as a standalone so it has the engine
which opens the stack with the code and data that I want to protect.

Bill,
1. I have heard that the 2.5 pswd is OK
2. I would have a separate stack as the start up and link to another
locked stack for the "Full stack protection".
3. Others here would know this. sorry.
4. ditto

I have a project where the data is stored in custom properties of
multiple cards in a stack that also has the UI for the user. Access
to the data by the user can be restricted by a password the user can
set. I want to protect my code in the stack as well.
What are the options in 2.5 to keep the data and stack structure
secure?
1. Will the password mechanism in 2.5 be sufficient to protect my
code?
If not, what are the options?
2. I want to allow the user to access the initial card of the stack
but require a password (that they can set) to access any other cards.
Access should be granted for as long as the user has the stack open
(like a lot of web pages). Once the stack is closed, or on an
openStack, or the user wishes to lock it again, the lock should be
in place.
Would it work to check the value of a variable, field contents on a
card that is not the initial card, or some custom property somewhere
to grant access to the destination card?
3. How strong is the encryption that is built into the locking stack
password?
If it isn't strong enough, what other options are there?
The product has to work without requiring access to the Internet for
public key/private key exchanges and the program needs to be able to
save changes in a way that leaves the data file always protected.
4. Is doing this in a stack the right approach or would it be better
to have a binary data file like more traditional programs? If a data
file is the right way to go, how can that be protected?
Please let me know what you think.
Thanks,
Bill Vlahos
