Something sounds very wrong when you say RBAC is not an option.

comment Is there any reason someone wouldn't use a longer key?
That text sounds pretty good to include in your answer ;) Afraid I can't give you a second upvote though :(

Well if you can modify the file, you can also delete it or change the key it's encrypted with. That would work of course. Other than that... well I guess I'll let others answer, but I'm not aware of any such technique.

+1 for being the only one to mention elliptic curves. What I've always wondered though: is ECC also faster than RSA when using a key with roughly the same strength (e.g. 2048-bits RSA and 224-bits ECC)?

What about ECC? The question is about public-key cryptography, not necessarily only RSA. I know ECC has shorter keys for the same amount of entropy, but I've always wondered if en/decryption is also faster.

Quite a big text, I read through it pretty quickly... I think what you want is impossible. If the encryption 57d478bae748f2 with key 6a47ce decrypts to "attack at dusk" today, it will still do so tomorrow.
