Title: OPNsense on Atom Processor and encryption
Post by: sweetfoxxy on January 11, 2021, 10:54:30 am

Hi

I need a bit of your experience and help
Q1: Does OPNsense support Intel Atom processors?
Q2: Is it possible to use hardware-based encryption with OPNsense?

Hi Nadzya,

Atom CPU's are supported as long as they have an Intel 64-bit instruction set. For crypto hardware-assist, check that they support Intel AES New Instructions.

The Ark is your friend: https://ark.intel.com/content/www/us/en/ark.html and search for the model number.

Performance is of course another matter - especially for IDS, VPN, web proxy, etc.

Hi,
It must support Atom but, it no enough power for firewall usage
It is possible to use hardware encryption, but, Atom processor don't have AES-NI   IMHO

Nonsense, sorry...

Nonsense again, e.g.

I'm sorry but, in first post, this in no infos about atom reference.
The C3558 has AES-NI but olders Atom no ...

No context in demande, no contexte in response  ;)

Thank you for your replies!

I have one follow-up question
How to enable hardware encryption on OPNsense? And also, can OPNsense use, for instance, Intel QAT API for cryptographic hw acceleration?
Please, share your knowledge

That's the (generic) Atom AES-NI acceleration.

_Some_ Atom SoC's have an extra dedicated QAT engine (encryption / compression), so you can (partly) offload the Atom offloading ;-).

There's a FreeBSD driver available and provided by Intel: https://01.org/intel-quickassist-technology

This isn't (yet) supported by OPNsense, is it ?
