SHA512 within Silverlight is not available, is there a managed library available?

Question

SHA512Managed is missing in Silverlight (for Windows Phone 7 CTP SDK), only upto SHA256 is available for use. Does anyone know a .NET class that I could use that offers a self-contained C# or VB.net SHA512 implementation?

I need to use this for authentication to a HTTP web service.

Thank you

Silverlight does not contain the System.Security.Cryptogray namespace. However, you could always port the open source BeeCrypt Cryptography Library (written in C), and use it directly in Silverlight.

Using HashLib from http://hashlib.codeplex.com/ will work fine. There is methods within HashLib.HashFactory.HashCryptoNotBuildIn that do not require System.Crytography
