PLX7820 hardware security engine support?

[firefoxPL]

Hi, I was wondering whether ALARM takes advantage of hardware security engine built into the SoC, it is supposed to support hardware acceleration of AES128, AES256 and some hash function (probably SHA1) calucations. For me it would be really great if those engines were used by openssl. My Pogo sometimes needs to handle some 5-6 Mbps encrypted traffic and it seems to handle the load, but during that time (tens of minutes sometimes few hours) I can't do anything with the pogo, not even ssh into it or view a simple web page that runs on it. Seems to me that openssl is completely taking over CPU (and possibly RAM) therefore I'm afraid that it does all the crypto calculations with CPU instead of using dedicated resources.
Could anyone confirm (built-in or lack of) support for the cryptographic resources of PLX7820?

We're working on the driver for it for 3.1, as it was essentially missing.

Despite that: openssl has to be compiled to make use of the logic.

Thanks for quick reply, in that case I have one more feature to look forward to in 3.1

openssl will still have to be compiled to use it.

Ok I get it , that shouldn't be a problem, I'd just compile it on the pogo or cross-compile on my laptop

I am hoping that rsync will be able to take advantage of this module for its file-block digesting/hashing needs. That's where my PPPro is spending the most cycles at present.

Good to know, for personal use AES128+SHA1 is sufficient, and should get best performance, SHA2 has some drawbacks to its algorithm that make it harder to implement in hardware where all calculations are parellel.
