NAME

       yhsm-generate-keys ‐ Generate AEADs with secrets for YubiKeys using a YubiHSM

SYNOPSIS

       yhsm-generate-keys --key-handles KEY_HANDLES --start-public-id START_ID [options]

DESCRIPTION

       With this tool, a YubiHSM can generate random secrets (using it's internal true random number generator),
       and these secrets protected in AEAD files can be stored on the host computer.

       The AEADs will be ready to be used by for example yhsm-yubikey-ksm(1) ), as  a  part  of  a  YubiKey  OTP
       validation service.

       To program YubiKeys with the generated secrets, it is possible to decrypt the AEADs (knowledge of the AES
       key used inside the YubiHSM is required) using yhsm-decrypt-aead(1)

OPTIONS

       -D, --device
              Device file name (default: /dev/ttyACM0).

       -v, --verbose
              Enable verbose operation.

       --debug
              Enable debug printout, including all data sent to/from YubiHSM.

       -O dir Base output directory (default: /var/cache/yubikey-ksm/aeads).

       -c integer
              Number of AEADs to generate.

       --public-id-chars integer
              Number of chars in generated public ids (default: 12). Changing this might not work well.

       --key-handles kh [kh ...]
              Key handles to encrypt the generated secrets with. Examples : "1", "0xabcd".

       --start-public-id id
              Public id of the first generated secret, in modhex.

       --random-nonce
              Use random nonce generated from YubiHSM.

EXIT STATUS

       0   Secrets generated successfully.

       1   Failed to generate secrets.
