I'm using Yubikey4 as my smart card with my StartCom Class 1 login certificate. My problem is: windows don't want to use this card.
Windows credential manager: "No valid certificates were found on this smart card".
Microsoft office doesn't see this card.
Windows VPN: "A certificate could not be found that can be used with this Extensible Authentication Protocol."
Keepass2 (RSA Certificate Key Provider plugin - uses windows security): "No cerficiate available. No certificates meets the application criteria." (of course tested with RSA certificate too).
My certificate details:
Key Usage: Digital Signature, Key Encipherment, Data Encipherment (b0)
Enhanced Key Usage: Client Authentication (1.3.6.1.5.5.7.3.2), Secure Email (1.3.6.1.5.5.7.3.4)
Public key parameters: ECDH_P384
From device manager:
Smart card name: "Identity Device (NIST SP 800-73 [PIV])"
Smart card reader name: "Microsoft Usbccid Smartcard Reader (WUDF)"
Is there any key usage required for smart card usage?
