comment Time Capsule cryptography?
I suspect most things encrypted with a scheme such as this will be opened late or never, because nobody is prepared to put that much effort into opening it (eg, nobody cares).

comment How do I construct a 256-bit hash function from 128-bit AES?
@joeforker Do you really anticipate generating on the order of 2^64 messages anyway? That's a lot of messages. As in, if you generated 1 million messages a second, it would still take you half a million years.

Requiring a certain amount of computation isn't the same as requiring a certain amount of time to pass, though.

I think you're completely missing the point here. The OP is trying to build a system to generate per-site passwords from a master user password, like SuperGenPass does. He's not asking about password storage on a server.
