Usage

Overview

-h, --help

Print help and exit

--full-help

Print help, including hidden options, and exit

-V, --version

Print version and exit

-v, --verbose[=INT]

Print more information (default=`0')

-r, --reader=STRING

Only use a matching reader (default=`Yubikey')

-k, --key[=STRING]

Management key to use, if no value is specified key will be asked for (default=`010203040506070801020304050607080102030405060708')

-a, --action=ENUM

Action to take (possible values="version", "generate", "set-mgm-key", "reset", "pin-retries", "import-key", "import-certificate", "set-chuid", "request-certificate", "verify-pin", "verify-bio", "change-pin", "change-puk", "unblock-pin", "selfsign-certificate", "delete-certificate", "read-certificate", "read-public-key", "status", "test-signature", "test-decipher", "list-readers", "set-ccc", "write-object", "read-object", "attest", "move-key", "delete-key")
