In lieu of a formal definition, for me it means at a minimum not clear text,
but also goes further to be not merely binhexed or other common algorithm.

In the the case of password-protected stacks it means whatever level of
security is provided by the engine's password encryption.

I'm imagining tucking data into a stack file as a custom property,
effectively using the stack file as a form of security wrapper.  The
additional ovehead of the stack structure is just a few k, and the mechanism
simple-to-use and fast.

Have you successfully cracked MC's password protection (please don't post
the algorithm if you have)?

PGP would be ideal, but while we wait for that I'm wondering what markets
would be satisied with merely "hard to crack" data as opposed to "extremely
had to crack".
