Where can I find a C# class for "Shamir's Secret Sharing"?

I am trying to find a class or something that would allow me to do Shamir's Secret Sharing.

I found a program in C# that allows you to do it but it does not supply source code. I was just wondering if anyone has a class that already does what I need.

From stackoverflow

• Why not use ILDASM or Reflector to get the source from the application you have?

• SecretSharp (linked from the wikipedia article) is GPL - you can browse the code here.
