<p class="Pp">The <code class="Nm">ubsec</code> driver registers itself to
accelerate DES, Triple-DES, MD5, SHA1, MD5-HMAC, and SHA1-HMAC operations
for <a class="Xr">opencrypto(9)</a>, and thus for <a class="Xr">ipsec(4)</a>
and <a class="Xr">crypto(4)</a>. The driver also supports acceleration of
AES-CBC with the BCM5823 or newer.</p>
<p class="Pp">On those models which contain a public key engine (almost all of
the more recent ones), this feature is registered with the
<a class="Xr">crypto(4)</a> subsystem.</p>
<p class="Pp">On all models except the Bluesteel 5501 and Broadcom 5801, the
driver registers itself to provide random data to the
<a class="Xr">rnd(4)</a> subsystem.</p>
