说明
ykinfo queries a connected YubiKey device and displays its identification information. It can report the serial number, firmware version, and supported capabilities of the hardware token. The -a flag shows all available information at once. Individual flags like -s (serial), -v (version), and -c (capabilities) display specific details. Quiet mode (-q) outputs values without labels for use in scripts. When multiple YubiKeys are connected, the tool can select a specific device by serial number. It is part of the yubikey-personalization package and is useful for diagnostics, inventory, and scripting around YubiKey management.
