About this tag
Discussions about private key management in Windows environments cover issues with CNG API retrieval, certificate renewal resetting permissions, and PKCS#12 import/export problems where the private key is missing from the PFX file.

These threads focus on Windows 7, Windows Server 2008 R2, and related tools like Certificate Manager and Visual Studio 2008, highlighting practical troubleshooting for private key operations.
