I am trying to generate ed25519-sk and ecdsa-sk keys using ssh-keygen on my Windows computer. I have OpenSSH OpenSSH_for_Windows_8.6p1, LibreSSL 3.4.3 installed and Yubikey Firmware version: 5.4.3. But, when I do ssh-keygen.exe -t ed25519-sk -C "[email protected]" I get below error
Generating public/private ed25519-sk key pair.
You may need to touch your authenticator to authorize key generation.
Key enrollment failed: unknown or unsupported key type
However, generating ecdsa key works fine.
Can anyone please let me know how generate ed25519-sk or ecdsa-sk keys to use with Yubikey and Gitlab?
Thanks in advance
