继续补充。

经过测试，这样只是生成了 CRT 证书，还需要把对应的 SSH 密钥写入 Yubikey 才 OK 。

# 生成的私钥要转换成 PEM 格式的文件，尽量不要设置密码
# 如果有密码，请在后面加上-p 参数取消即可
ssh-keygen -f private.key -m pem

#导入证书文件
C:\>yubico-piv-tool -s 9a -a import-certificate -i mykey.crt
Successfully imported a new certificate.
#导入密钥文件，触摸策略是每次都 touch，可选 never 、cached
C:\>yubico-piv-tool -s 9a -a import-key --touch-policy=always -i private.key
Successfully imported a new private key.

感谢，已经用 gpgsm 命令生成了自签名证书并写入 YubiKey
```
根据 OpenPGP 密钥生成自签发的证书

用 YubiKey Manage 导入刚才生成的 client.crt 文件
打卡 YubiKey Manage->Application->PIV->Configure Certificates->Authentication(Slot 9a)->Import
