-/*
- * Demo on how to use OpenBSD /dev/crypto device.
- *
- * Author: Michal Ludvig <michal@logix.cz>
- *         http://www.logix.cz/michal
- *
- * Note: by default OpenBSD doesn't allow using
- *       /dev/crypto if there is no hardware accelerator
- *       for a given algorithm. To change this you'll have to
- *       set cryptodevallowsoft=1 in 
- *       /usr/src/sys/crypto/cryptodev.c and rebuild your kernel.
