Hi Jonathan,

about your question to execute 'openssl speed' command on my
environment, it is not possible because now I am in pre-doctoral stay in
Switzerland :(

About your problem SSH, I had some problems too, but nothing important.

My last work was the same that you proposed. I implemented a hardware
accelerated version of SSH using MicroBlaze-uClinux. The connection
between MicroBlaze and the cipher cores was made using the FSL
interface. I tested only the AES-128 and 3DES, but I have implemented
the IDEA, Blowfish, DES, RC4, MD5 and SHA-128/256 algorithms. In this
work I measured the performance obtained using the pure-software version
and the hardware-based version using the scp application. Also, the
different cipher cores are partial reconfigured at run-time, that is,
the MicroBlaze downloads from Internet the negotiated cipher core
(partial bitstream), configures the FPGA (self-reconfiguration) and uses
it. If the next time the algorithm changes, then MicroBlaze can
reconfigure the core again with the new cipher :P
If you are interested, we can talk about it out of the mailing-list
(because I think that it is an off-topic). I can give some suggestions
in order to improve my results :)

Regards,

Ivan
