Hello,

I have an interesting issue with the .Net Framework 2.0. We developed a
VS6 C++ COM dll that incorporates all of our security related
operations including encryption/decryption. We are using the CryptoAPI
and have had great success with it so far. All of our .Net Applications
were initially written and compiled against .Net 1.1. All of the
applications work correctly with the security com objects when running
under 1.1.

The issue is when we upgrade the c# code to .net framework 2.0. Now all
of the security objects do not operate correctly. All of the
decryptions do not work for encrypted strings that were encrypted using
1.1. Since we still have portions of our software running as native C++
or .Net framework 1.1, we can not just encrypt everything with 2.0.

Has anyone encountered this issue at all?

Jim
