You CAN make it difficult if you like... But remember the trade offs. The biggest advantage of doing offload in the first place is not having to doit to the backend... So the backend doesn't have to do the processing... Of course with longer keylengths you can trade off security with a shorter keylength for the server side... But generally in most environments you're not buying a lot when you re-encrypt... If an attacker can snoop your backend traffic (WHich is what serverside SSL is guarding against), you're already broken...
