[En-Nut-Discussion] Any Encryption available for Nut/OS?

[Ulrich Prinz]

Hi!

I only had time to take a very short view on it, but it looks 
interesting and promising. As fas as I can see, the polar is a spiinof 
from xyssl. The xyssl is maintained but only by one guy now. It is 
available as a GNU version and as a BSD version. So we could implement 
it in both options.
For me it is only an experiment if I have some time to spare. May be 
later it might become interesting for business too and then it is easier 
for me to know what I am talking about if I have to decide the platform 
for the new project.

Meanwhile, thnaks for the hint.

Best regards, Ulrich
