But Steve, isn't this bulk-rate encryption speed? I.e. key setup
is done once, and then you pipe your data in as fast as you can?
While during cryptanalysis you must perform a new key setup with
every encryption (thus slowing down considerably)?
Any numbers on how many key schedule setups per second can one do?
