    While Silverlight is a powerful tool for rich client applications, it lacks the ability to perform asymmetric encryption out of the box. In this article, I'm going to share a cryptography class library I've been working on and show you how to use it to perform standards compliant RSA Encryption in Silverlight that is cross compatible with .NET's built in RSACryptoServiceProvider, allowing you to encrypt from Silverlight using my library and decrypt on your website using the RSACryptoServiceProvider. For brevity, only examples using my class library will be shown except for a few examples that show equivelant functionality from the RSACryptoServiceProvider (RSACSP).


  • Encryption in Silverlight and .NET Applications

    Sergey Barskiy posted the code for a solution allowing encryption in a Silverlight client.

    Today I would like to cover a specific use case that came up a few times in Silverlight applications I wrote.  For example, I wand a user to enter some sensitive information, encrypt it in Silverlight client, transfer it over to the server, then decrypt it and perforation some operations on that data.

    First step of course is to find sufficiently strong encryption protocol that can be implemented in both Silverlight and .NET and be completely compatible between both run times.  I am going to go for AES encryption.  AES stands for “Advanced Encryption Standard”.  This standard is widely used and approved by US government and standard bodies.  See this article for details.
