You may know that System.Security.Cryptography for Compact Framework lacks many cryptography algorithms compared to the desktop .Net Framework (2005 and later). In a project we have needed SHA512 encryption on Windows CE and we have found /cfAes library which provides almost all of the crypto functionality of .NET Framework. We are grateful to the author for sharing the class library.
The following table displays a comparison between the versions of .Net Framework with respect to the support for different crypyography algorithms (X means that it is supported, 0 means partially supported).

Can you share cfAes library? There is no http://www.mperfect.net site availiable.

Many many thanks for your library. It was very helpful for porting sha256 to a wince platform using .netCF which natively doesn’t support it.
Thankyou, Norm.
