Hi Matthieu,

I do not know about the native mono lib, its at a standstill as far as I 
know. However I have successfully used the SecureBlackBox from Eldos 
under mono 2.6.x/2.10.x

It is not that well documentated, but the support is very helpfull and 
the price is within a reasonable level in my mind.

Have a look at this link: http://eldos.com/sbb/desc-pki.php

You can get a trial key for testing..
