I’ve been working on organizing the code for my old custom Symmetric
Encryption Pipeline Components for BizTalk Server 2006 and I’ve posted the updated
code on a new GitHub repository.
Be aware that I renamed things a little bit and cleaned other parts of the code.

The code includes both the encryption and decryption component, some basic tests using PipelineTesting,
and the Windows Forms Configuration Utility that stores the crypto keys used by the
components in a custom Configuration Application in Enterprise Single Sign-On.
