Hostapd with AES-capable WiFi card = hardware AES or software AES?



  • I've seeking over the internet but no answers found.

    I have a board with Atom N2800 (with no AES-NI), and a high-end 802.11n wifi card (AR9590) with AES encryption/decryption offload support.

    Now I'd like to build a pfSense router, and with this configuration. The question is,

    Will hostapd offload the AES encryption/decryption to the wifi card? or use openSSL + CPU?

    The FreeBSD 802.11 driver page claims that it does support hardware offload for that, but it doesn't give details that I've spotted yet.

    It may be supported in 9-stable/10.x but not FreeBSD 8.3, but at the moment the only way to know would be to try.
