You could download the .NET 4 beta and use <code>System.Numerics.dll</code>, then just distribute that DLL with your code. As to the rest of your question, there is already <a href="http://msdn.microsoft.com/en-us/library/system.security.cryptography.rsa.aspx" rel="nofollow">support for RSA built into the .NET framework</a>, or are you trying to write your own implementation as an exercise? Robin,

I use Visual Studio 2008 for Visual Basic .. I can add the BigNum dll as reference (include the dll~) but at runtime it says it can't use gmp.dll because it's not a valid assembly or COM component :S I need BigNum for Visual Basic to handle RSA cryptography Hi Porges, I hope you’re still active?

Thanks! Hi Bart,

Currently I am trying to write a program which will calculate large amounts of Pi digits and find any pattern in it. I would be very thankful, since I don't remember when I last wrote something in C++ (recently only c#). In my case time is a key issue. Please excuse me if I wrote something unpleasant. My English is not on a high level. If you are interested I am a Polish Warsaw University of Technology student. Regards -- Dawid Rutyna Hello,

I hope this works. I've been looking for something like this for a long time. I'm initially planning to use it with the Boo .net programming language, exploring the Collatz problem. Great!
