Project Overview:
Our product – a passwordless MFA system. It provides strong protection for all login dialogs, services, and network protocols by eliminating Windows passwords completely from the network. By using the native Windows PKI functionality, logging into Microsoft Windows-based environments is done without additional up-streaming and without Azure. All digital certificates are managed on the server and are not saved on client devices.
The Windows client and some VPN parts are written entirely in C++ and will have to stay that way (Microsoft’s requirement). The server is written in C#. Other components are written in C#, but some of them have constraints or special requirements, i.e., COM-connectors, WinForms usage, MMC snapin-model, etc.
All components, including native ones, communicate with each other via WCF.
