ASA - crypto hardware processing

When implementing DH groups for Phase 1 key exchange of a VPN connection on a Cisco ASA device, it is best practice to enable hardware processing instead of software processing.

This can be achieved using the following command:

crypto engine large-mod-accel

The command was introduced in ASA version 8.3(2) and is available on the ASA 5510, 5520, 5540, and 5550 platforms.
