are properties safe?

Are properties stored in a run-only script “safe” (for storing passwords etc) or somehow accessible from “the outside”?

No!!!
Not at all.

I’ll add that you can use the standard Keychain to store sensitive info (check “Keychain Scripting”'s dictionary, in your “/System/Library/ScriptingAdditions” dir, or search for “Keychain AND Scripting” in this bbs).

Thank you!
