Having gone though a PCI audit, this may be my own sensitivity, but you may
want
to consider using host-specific encryption tools when you save any sensitive
personal data on disk (unless it is only _your_ personal data :).
Here is the doc for what I use:

Thanks, Bill, I suspected that.
Component files not a bad idea, Rick. Not too hard for a preoccupied mind.
Or an ordinary file and apply a Caesar code (so crude!). Just thought
an encrypted script might be slicker & more general, and to-hand, but
doesn't seem so in practice.

Would using component files to store your data be enough. The scripts
would still be in clear text but would pull the sensitive personal
data from the component files.

jfiles and keyfiles are available in the data/jfiles addon
I think there
please also take inot account that lock script does not hide global nouns.
You may test with your class browser on lock scripts.

Not immediately clear how to use it, though. And not sure if it's what
I want. However I note the existence of:

Just today my imagination seems to have deserted me...
Has anyone got a neat well-tried method of saving/reloading a J script
in encrypted form? Just to hide lists of sensitive personal data from
casual prying. It doesn't have to be proof against someone who knows J
and knows what the script does.

You want 3!:6 . It's described lightly at

Dear J Forum:
Years ago I knew how to encrypt a script so that it could not be read; now
I've forgotten. Would someone please show me how to do it, or at least
direct me to the J literature on it. Thanks.
