The cryptography services in Silverlight today only include the SH1 algorithm. That’s quite useful, but throughout the web there is still a significant use of the MD5 algorithm today. This is a re-post of a managed code implementation of MD5 that has been working great for my Flickr API work.

To use this component in your own Silverlight 2 Beta 1 project, you can grab the bits either way:
Download Md5.cs
Download JeffWilcox.Md5.dll (zip, referenced component can be used by C# and VB Silverlight 2 beta 1 apps)

The MD5 types are in the namespace JeffWilcox.Utilities.Silverlight, so that it doesn’t *** with anything. Feel free to rename the namespace to suit your project’s needs. The easiest way to use these bits is just to add a reference to the assembly to your project, the MD5 assembly will then be included in your finished app’s .Xap file.

While working on implementing the Flickr web services API within a .NET-enabled Silverlight sample application, I needed to use the MD5 algorithm that isn’t available within the cryptography APIs. Like many REST-based web services, the simple Flickr API uses MD5 along with a form of “signing” with a known secret.

The excellent MD5 implementation was created by the GL Conseil/Flow Group SAS; they did this work to enable MD5 within the Compact Framework 2.0.

Calling the function is very simple. In C#:

And in VB:

Hope this helps!
