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

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)

-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.

0

Secrets generated successfully.

1

Failed to generate secrets.
