Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

padlock_load="YES"

The padlock driver registers itself to accelerate AES operations and, if available, HMAC/SHA1 and HMAC/SHA256 for crypto(4). It also registers itself to accelerate other HMAC algorithms, although there is no hardware acceleration for those algorithms. This is only needed so padlock can work with ipsec(4).

The hardware random number generator supplies data for the kernel random(4) subsystem.
