BTW: Since parts of the OpenSSL library are already written in Ruby (see 
ruby-1.8.6p368\lib\ruby\1.8\openssl directory) it might be easier to write the 
rest in Ruby as well. With calls to .NET implementation of the cryptographic 
algorithms, of course. 
If you chose to go that way you can add the scripts to 
Merlin\Main\Languages\Ruby\Libs.

It depends whether the method is supposed to invoke Digest's methods 
dynamically or not. Does pkcs5_keyivgen method accept any Ruby object that 
implements the methods pkcs5_keyivgen calls? Or does it need to be an instance 
of Digest class?
If the former is true than you need to use "object" as the parameter type and 
use dynamic call sites to invoke those methods. An example of such dynamic 
behavior would be MutableStringOps.Compare. If the latter is true you can just 
type the parameter to Digest CLR type and call its methods directly.

Subject: [Ironruby-core] handling ruby types and CallSiteStorage in std library

I'm working on adding code to the OpenSSL extension of the standard library and 
I need to understand the design for invoking and typing Ruby code.  I read the 
'Modifying the sources' github page and it mentions using CallSiteStorage to 
call into Ruby code.

Specifically, the Cipher ruby class has a dependency on the Digest ruby classes 
for the pkcs5_keyivgen method.  An optional parameter for this method is an 
instance of the Ruby class Digest::Base.  How would the type look, maybe 
Digest.Digest.Base digest/*optional*/? Or would it be an object and I'd also 
need to pass in CallSiteStorage to call methods on the object?

An example in the standard library of such behavior would be much appreciated, 
thanks for any help.
