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

问题

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.

回答1:

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

回答2:

Mono has an implementation you could probably use, provided you are happy with the OS license.

回答3:

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.

As there is no support for SHA512, we have to use our own or 3rd party implementations. (Check msdn here..)

Chilkat's implementation worked for me. It is very simple & straight-forward to use. Check it out here..
