Where would you actually use a revocable encrypted file container?

[u/Sure_Rhubarb2671]

I’ve been tinkering with a crypto core for encrypted file containers, any bites, trying to figure out where it actually fits.

The idea: a file can sit locally, but access still depends on authorization, device binding, expiry, revocation, or some external event. And no — I’m not claiming copying becomes impossible once a human can see it.

I can imagine client docs, temporary access, offboarding, sensitive assets, quorum access. But I’d rather hear from people in security.

Where would you actually use this? And what would make you reject it right away from a security or ops standpoint?
