Xamarin Studio breaks on Window systems that enforce FIPS compliant hashing (http://blogs.msdn.com/b/shawnfa/archive/2005/05/16/417975.aspx). System.Security.Cryptography.MD5.Create throws an exception, since MD5 is not FIPS compliant.

http://forums.xamarin.com/discussion/8633/xamarin-studio-not-getting-started#latest

We should make these features degrade gracefully, or bundle Mono's MD5 implementation.

Also, IKVM.Reflection is broken since it uses SHA1Managed, and this causes much more serious problems.

It may be possible to fix that by using SHA1CryptoServiceProvider.
