Jacques,
Since your client has the requirement of no externals, I think there is
still one way to encrypt the data, using nothing but the engine.
Isn't it the case that if you store data as custom properties in

There is no harm in using SHA1 in a scrambling/encrypting function of this
type. The longer key might make it harder to crack. (Redoing the key based on
the previous key every so-many characters might also help.)
However, there is a tiny way in which MD5 is better. It is faster. That might

It's even harder if you offset those by 2: A=3, B=4.

I'm not sure how it's done exactly. Mark Waddingham mentioned it to me at the

Swaps into and out of an SSD take about a tenth the time.

A commercial desktop app doesn't have any control over that, unfortunately.

Jacque,
For as long as I can remember, the developer has been able to specify the OS
Version, the amount of RAM, and the amount of disk space required for a
program. If the program really requires 16 G of RAM or an SSD, the developer
should specify that as well.
Small SSDs (60 G) are less than
I just can't remember what it was, but I recently saw an app that would not run
at all unless it could perform well.
Short of that, you can list system requirements.
But maybe (eventually) a commercial app should run well even in typical RAM.
Now, what is typical RAM?

It's for students and they will run the app on their own machines. My

Now, I'm being (half) goofy.
You can have a student and homeschool version which limits the student to some
number of things being worked on and has a requirement of 4G. You can have a
school or teacher or government institution version that has no such limit and
has a requirement of 8G.

Perhaps school districts have guidelines for memory requirements of
