There are a number of hardware solutions for performing AES-CTR in 
hardware - for example the broadcom BCM5825, which is supported by the 
ubsec driver.

The problem is that OpenSSL does not currently support hardware 
acceleration of AES-CTR.  The solution on a Sun system is to use the Sun 
crypto framework APIs (PKCS#11) which does support AES-CTR in hardware.

Is there an analagous API in FreeBSD that I could implement in my code so 
as to use the hardware AES-CTR of devices supported by ubsec ?

Or do I need to directly manipulate ubsec with my actual application in 
order to do this ?
