[Vm-dev] [Cryptography Team] Porting the Cryptography library to use libsodium

[rabbit]

I took a look at SqueakSSL and there is a SqueakVM Plugin built, with 
platform code, a Cross header for the Plugin and source generated from 
the image. This plugin has a tight interface (only about 8 methods) 
which call the SSL OS library.

As the protocol interface for libsodium is likely quite sizeable, I 
think I would prefer adapting to use FFI to talk to the shared object 
lib, libsodium.so. I cannot find an example using FFI, in fadct I do not 
think it is loaded.

Is it possible, you can point me to an example of using FFI to talk to a 
shared lib?

Thanks!

Have a good one; keep it, light.
