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.
