No certificate in certmgr despite it being present on the key #42

I've followed the documentation with a yubikey 5 nano. I think I got the key+cert generated properly:

PS C:\Program Files\Yubico\YubiKey Manager> .\ykman.exe piv info

but despite re-plugging the key, windows doesn't see the cert: image

I'm not all that familiar with win10's plumbing involved here - anything that I might have missed?

Thanks!

Please try to use RSA2048 instead of ECCP384 to generate key pairs and certificates. Some settings may cause the ECC certificate to be unusable. See also:

Ran into this today as well, created a PR #44 to add a note about this in the documentation. After enabling ECC keys it worked.

kipters commented 3 years ago

It didn't work for me (even after enabling the policy and rebooting)

dschaper commented 3 years ago

Are you using the Yubico MiniDriver for your key or the default Windows card services driver? Check your Device Manager and see how the key is listed.

kipters commented 3 years ago

@dschaper The default I think, I didn't install anything from Yubico, except ykman (it's a fresh Windows install)

Same Issue here.

PS C:\Users\GottZ> ssh-add -s "C:\Program Files\Yubico\Yubico PIV Tool\bin\libykcs11.dll"
Enter passphrase for PKCS#11:
Could not add card "C:\Program Files\Yubico\Yubico PIV Tool\bin\libykcs11.dll": agent refused operation

certmgr.msc doesn't list the key either.

EnumerateECCCerts is set to 1

device manager lists it properly as smartcard image

I'm on Windows 11 Pro OpenSSH is not started. I can't get libykcs11.dll to work with it either.

I have no problems using this key with PIV on a native Archlinux installation.

ssh-add -L should spit out my ecdsa-sha2-nistp384 key from the yubikey but does not.

I do have gpg4win installed but no daemon is running right now.
