determining if a stack is locked

[Richard Gaskin]

With v4, the engine now uses a more secure method to secure scripts, but 
in my testing it has also removed any way to determine when a stack is 
password-protected without using "try".

In versions prior to v4, you could do this:

    if the password <> the passkey then ...

The password and passkey returned an encrypted string which, while 
meaningless to the human reader, would at least allow comparisons of the 
password and passkey to determine if the passkey had been set in the 
current session, or if there is no password at all.

In v4 and later, asking for the password or passkey returns simply 
"true", which might be sufficient but here's the rub:

If you start a new session with a locked stack, asking for the password 
will return "true" which is correct, but asking for the passkey will 
also return "true" which is incorrect, since no passkey has yet been 
entered.

I would expect that asking for the passkey of a stack that has a 
password would return "false" until a passkey has been entered in the 
current session.


I discovered this with stacks in which the password had been set in a 
previous version, but I just confirmed it in v4 using this recipe:

1. Make a new stack
2. Set the stack's password
3. Run this in the Message Box:

    put the password of this stack && the passkey of this stack

You'll get "true true", which is appropriate because the stack's 
password was set in this current session and therefore its script is 
available.

So now continue this test:

4. Save your stack and quit
5. Re-launch Rev, and re-open the stack
6. Run that command again in the Message Box

RESULT: "true true", which seems inappropriate because the passkey has 
not been set and the stack's script cannot be accessed until it has.


So this leads me to two questions:

1. Can anyone here spare a moment to confirm this behavior, and does it 
seem inappropriate to you?

2. What method exists in v4.x to determine if a stack has its password 
set but no passkey has been entered?
